Occupancy calendar for small stays

The calendar is free.
Forever.

InnGrid keeps your rooms and bookings on one clear board — guesthouses, B&Bs, cottages, agritourism. Day guests fit too: dog day care, day rooms, breakfast guests. Built to read one-handed, in the doorway, with no signal.

  • Zero double bookings
  • Works offline
  • No account
  • No per-room fees

Free booking calendar for small stays. Premium adds Booking.com and Airbnb import, private iCloud sync across iPhone, iPad and Mac, multiple buildings, and calendar sharing.

Download on the App Store

iPhone · iPad · Apple Silicon Mac · 14-day free Premium trial

No fine print

A complete booking calendar for free. Upgrade to import Booking.com and Airbnb, sync every device, manage multiple buildings, and share a calendar with your team.

The reservation calendar costs nothing and works fully offline — no stripped-down version, no charge per room. Premium automates the rest: bookings imported from Booking.com and Airbnb, the same calendar on iPhone, iPad and Mac through your own private iCloud, several buildings on one board, a calendar you can share with a co-host, and a staff link that shows the person who cleans what to clean and nothing else — neither of them pays a thing. Try it free for 14 days.

At a glance

A whole month, one screen.

Rooms down the side, nights across the top. Scroll the season and zoom from a week to a month — instant, offline, all on your device.

No double bookings

Overlaps you can’t miss.

InnGrid refuses two confirmed bookings on the same night. When stays do overlap they stack in plain sight, with a warning — never hidden behind each other.

Yours alone

No InnGrid account. No developer-hosted booking server.

Your bookings stay on your device. Premium can sync them through your private iCloud, and calendar import connects directly to the feed you provide.

Fast to log

A booking in three taps.

Tap a night, name the guest, save. Track who’s paid, who arrives today, and what the month earns.

Meals, counted

Who eats what, without a second list.

Mark Breakfast, Lunch or Dinner on a booking — InnGrid works out from the dates which day each one falls on. The kitchen sees today’s count, the cleaner’s list carries the meals, and the guest’s confirmation names them too. Free, like the rest of the calendar.

Work together

One calendar, your whole team.

Share a building’s calendar with a co-host (Premium) — they see it, or even edit it, on their own Apple Account, free of charge. For the person who cleans, “Invite staff” sends a narrower link: the rooms and what needs doing there, never your bookings, guest names or prices. They tick a room off with one tap, and you see the time and who did it.

Thirty seconds

See it work.

The real app, unedited: the board with calendars shared with you, today’s arrivals, calendar import — and a booking typed in seconds.

Straight from the app

Everything you need to run the calendar is free. Premium automates the busywork.

No locked buttons: the calendar below is the full product. Premium automates your work — import OTA bookings, keep iPhone, iPad and Mac in sync, manage multiple buildings, share a calendar with a co-host, and send the person who cleans a staff link — all without per-room fees.

Premium is a small yearly plan with a 14-day free trial, or a one-time lifetime purchase — current pricing is in the app. Only the calendar’s owner needs Premium — the person you share with uses the free InnGrid and pays nothing. Your data is never deleted if Premium ends: every reservation and building stays on your board and stays editable, and calendars you already connected keep refreshing — iCloud sync pauses, calendars you shared stop updating for the people you shared them with, and adding new buildings or calendar feeds needs Premium again.

Comparing tools?

Honest comparisons, including where the other one wins.

Alternative to BedBooking

No per-room tiers.

BedBooking prices by room count — its smallest paid plan is €194.99 a year for 1–3 rooms on the German App Store. InnGrid’s calendar is free forever for any number of rooms; Premium is optional at €22.99 a year.

Alternative to Smoobu

The calendar, not the platform.

Smoobu starts at €29 a month for one unit, plus a 0.9% booking fee on that plan and from €9.60 a month for each extra unit. InnGrid has no monthly fee for the calendar and no commission — but also no two-way channel manager, which is Smoobu’s whole point.

Questions

Fair questions, straight answers.

Is the calendar really free?

Yes. The board, bookings, guests, stats, housekeeping, backup and exports are free forever — no per-room pricing, no ads. Premium adds Booking.com & Airbnb import, sync across iPhone, iPad and Mac, multiple buildings and calendar sharing — with a 14-day free trial.

Do I need an account?

No. There is nothing to sign up for — every booking lives on your device. Premium sync uses your own iCloud; we never see your data.

Does it work offline?

Fully. The calendar needs no signal at all — in the doorway, in the basement, in the mountains. Only iCloud sync and calendar import touch the network.

Can I see my Booking.com or Airbnb reservations?

Yes — paste the calendar (iCal) link from your listing and those bookings appear on the board, read-only, refreshed in the background even when the app is closed, with an optional notification the moment a new booking arrives (Premium). Exporting your own calendar as an .ics file is free.

I run more than one building.

Premium lets you add buildings and see every villa’s rooms on one board, grouped under its name — and the housekeeping list covers them all.

Can I track day guests who don’t stay overnight (breakfast, day care)?

Yes — that is exactly what day stays are for. In the booking form, turn on the “Day stay” toggle: the check-out row disappears and the entry fills exactly one day on the board, never touching the neighbouring days — unlike an overnight booking, whose bar runs from noon to noon by hotel convention. Several day stays can share one room on the same day, each as its own named bar. If most of your entries are same-day, turn on Settings → Same-day stays → “Day stays by default”; a day guest returning all week can be entered as a range — one entry per day, saved together and drawn as a single bar with the name shown once. There is no per-day guest counter yet — hosts put the number in the entry’s name (e.g. “Breakfast – 8 guests”). If what you serve is breakfast to guests who are already staying, you don’t need a day stay at all — mark Meals on their booking and the Day plan tab counts them under “Kitchen today”.

How does sync between iPhone, iPad and Mac work?

Premium sync runs through your own iCloud: sign in with the same Apple Account on each device, and a booking added on your phone shows up on your Mac within seconds. For a co-host with a different Apple Account, use calendar sharing — see the next question.

How does calendar sharing work?

Each building’s calendar can be shared separately (Premium). In Settings → Calendar sharing, pick a building, add a participant by the e-mail address or phone number of their Apple Account, and choose what they may do — view, or view and edit. Then send them the calendar link. They open it on an iPhone, iPad or Mac with the free InnGrid installed (no InnGrid? the link routes to the App Store), and your calendar appears under “Shared with you” — on their own account, at no cost to them. Edits show up on both boards within moments while the app is open, and the housekeeping list covers shared calendars too. You can change a participant’s access or stop sharing at any time.

Good to know: the link works only for people you added first. If it arrives from a number that isn’t in the recipient’s contacts, iOS may show it as non-tappable — adding the sender to Contacts fixes that. There is no web version, so a participant needs an Apple device — Android or a PC browser won’t work.

Cleaning is a separate, narrower link: “Invite staff” gives that person only the rooms of one building and what needs doing there — your bookings, guest names and prices never reach their device — and they tick a room off with one tap.

Does it work with Google Calendar?

Yes, both ways. To see Google Calendar events in InnGrid, paste your Google calendar’s secret iCal address (Google Calendar → Settings → your calendar → “Secret address in iCal format”) into Calendar sync (Premium) — the same import that handles Booking.com and Airbnb. One honest limitation: recurring events import as a single entry (the first occurrence). To go the other way, export your InnGrid calendar as an .ics file (free) and import it into Google Calendar.

Can I get my data out?

Always, and for free: export an InnGrid data backup that you can import and merge later, a CSV file for spreadsheets, and an .ics calendar file — per room or for a whole building. Import such a file back and every booking lands in its own room. External OTA bookings return when their feeds sync again. Your bookings are never held hostage.

Which languages and devices?

English, Polish, German, Spanish, French, Italian, Portuguese, Brazilian Portuguese, Dutch, Czech, Slovak, Ukrainian, Greek, Russian, Indonesian, Japanese, Turkish, Hungarian, Swedish, Norwegian, Danish, Traditional Chinese, Vietnamese and Croatian — on iPhone and iPad (iOS 17 or later), and on Apple Silicon Macs (the same app from the Mac App Store, in a freely resizable window).

How do I change the app's language?

InnGrid speaks your iPhone’s language. To set it separately, open the iOS Settings app, find InnGrid in the list of apps and tap Preferred Language. Handy when your phone is in one language and you would rather keep the calendar in another — or when you want to check how the app reads for your staff.

How do I reach support?

E-mail [email protected] — questions, ideas and bug reports are all welcome. For sync questions it helps to attach the report from Settings → Help → “Copy diagnostics” (it contains counts and versions, never guest data).

Changelog

Recent updates.

  1. 1.9.2September 2026

    Reliability and polish improvements.

  2. 1.9.1September 2026

    Reliability and polish improvements.

  3. 1.9August 2026

    Note how many people are coming: a booking can carry a guest count, and the bar on the calendar shows it next to the name — Kowalski +3 when four people arrive; the day plan shows it beside the room, and the kitchen count can add up people and not only bookings · a notification when Booking.com, Airbnb or another calendar link brings in a new booking — also when the app is closed, and if that booking lands on nights already taken, the notification says so rather than leaving it to the calendar · see where a booking came from: imported and phone bookings now carry a small mark before the guest name, while direct bookings look exactly as before · leave a note for whoever cleans — type it on the room’s row in Day plan and it reaches the phone of the person you invited as staff, beside the room they tick off · eleven more languages, 24 in all · plus reliability and polish improvements.

  4. 1.8August 2026

    Ask InnGrid without opening it: type or say “InnGrid arrivals” or “InnGrid today’s plan” in Spotlight, in Shortcuts or to Siri — every phrase includes the app name, and that is how iOS finds it; the first time you ask, Siri offers to turn InnGrid’s shortcuts on: tap once and it answers from then on. Free, like the rest of the calendar · enter prices per night, if that is how you bill — choose it once in Settings → Money, or switch it on any booking longer than one night · a stay that runs across a month boundary now splits its revenue between both months by the nights actually spent in each, so a month’s total in Stats matches what happened in it; amounts you already saved are unchanged · Greek and Russian — 13 languages in all, and the app follows whatever language your iPhone is set to · plus reliability and polish improvements.

  5. 1.7.7August 2026

    Cleaning, from assigned to done: assign a turnover or a departure to whoever cleans it, and they tick it off with one tap — your Today tab then shows the time and who did it; a tick made with no signal survives closing the app and reads “unsent” until it goes out · “Invite staff” gives that person their own link to one building: the rooms and what needs doing there, never your bookings, guest names or prices — and free for them, like the rest of the calendar · your day on the Lock Screen: three widget shapes for today’s arrivals and departures, with guest names never shown while the phone is locked · press and hold a booking to change its status, share a confirmation or edit it, without leaving the calendar · a day-stay range across several rooms is now one booking · on a Mac, dialogs fit the window and Esc closes, ⌘↩ saves · plus reliability and polish improvements.

  6. 1.7.6August 2026

    Reliability and polish improvements.

  7. 1.7.5August 2026

    Fix: a booking could move into the wrong room — when a day stay was booked in several rooms, “Edit all days” rewrote every day to the room you had tapped. If you book day stays across more than one room, it is worth checking those dates in your calendar.

  8. 1.7.4July 2026

    See further into the past: keep scrolling the calendar left and earlier months load in as you go — or jump straight there with “Go to month”; “Today” always brings you back to the current day · better with accessibility settings: with increased contrast, reservation bars gain a clear outline, and with colour-free differentiation each booking status gets its own bar pattern — using neither, the calendar looks exactly as before · plus reliability and polish improvements.

  9. 1.7.3July 2026

    Editing a whole day-stay series: a day stay entered across several days is now fully editable — tap any day and choose to change just that day or all of them, including the length of the series; shortening it can be undone with a single Undo · better support for the largest text sizes: the calendar and the purchase screen stay readable, plus small VoiceOver improvements · restoring a backup now says clearly when everything in the file is already in your calendar, instead of “added: 0” · plus reliability and polish improvements.

  10. 1.7.2July 2026

    Kitchen counter in the widget: the “Today at your place” widget now shows how many bookings have breakfast, lunch and dinner today, without opening the app · export a room’s calendar as its own .ics file, and import a file covering a whole building in one go — every booking lands in its own room · Settings now show the installed app version, so you can see at a glance which one you are running · with several buildings, picking a room is clearer: the room list groups rooms by building · plus reliability and polish improvements.

  11. 1.7.1July 2026

    Fix: resolves a crash that could close the app shortly after opening when a shared calendar was used together with iCloud sync — your bookings were never affected; they stay safely on your device.

  12. 1.7July 2026

    Meals: mark Breakfast, Lunch and Dinner on a booking — InnGrid works out which day each one falls on, counts them under “Kitchen today” and puts them on the cleaner’s list and the guest confirmation; free, like the rest of the calendar · a day-stay range now reads as one bar with the guest’s name shown once, repeated along a long bar · tap a booking to preview it before editing — nights, balance due, tappable phone and e-mail, and “Share confirmation” right there · “Edit contact” on a guest’s card updates every stay of that guest, so the same guest no longer splits into two entries · a fresh install now offers to bring your bookings back from iCloud · fixed: reinstalling no longer revokes the calendars you shared, a participant can leave a shared calendar, and every calendar feed is listed whichever building you are viewing.

  13. 1.6.1July 2026

    Day stays: tap the last day of a selected range again to keep only that day — a single future day can now be picked directly in the calendar, where before every day in between got linked in; the calendar hint explains the gesture · Settings → Help now has a Contact support row that opens an e-mail to us — questions, ideas and bug reports are all welcome.

  14. 1.6July 2026

    Calendar sharing: give a co-host or cleaner their own view of your calendar — or let them edit it — on their own Apple Account, free for them; changes sync both ways in moments · the housekeeping list covers calendars shared with you · day stays with a date range — one entry per day, saved together · works with Google Calendar via its secret iCal address · fixed: an imported calendar whose building you deleted could keep running unseen — you can now find it in Calendar sync and remove it, along with its bookings.

  15. 1.5.1July 2026

    14-day free trial on the yearly Premium plan · check a calendar link before you subscribe — InnGrid reads the feed and tells you how many bookings it found · an honest iCloud sync status, so a stalled sync is never hidden · right-click on the Mac to rename or delete rooms, buildings and calendars · backup & CSV fixes.

  16. 1.5July 2026

    Mac (Apple Silicon): the same app on your Mac, in a freely resizable window · a board that stays fresh all day — it rolls to the new day at midnight and keeps synced calendars up to date on an always-on reception screen · guest-confirmation templates and PDF export for confirmations and the stats report · a board zoom control that stays legible in every language.

  17. 1.4July 2026
