Occupancy calendar for small stays
InnGrid keeps your rooms and bookings on one calm grid — guesthouses, B&Bs, cottages, agritourism. Built to read one-handed, in the doorway, with no signal.
Free booking calendar for small stays. Premium adds Booking.com and Airbnb import, private iCloud sync across iPhone, iPad and Mac, and multiple properties.
No account · no per-room pricing · 14-day free Premium trial
The whole promise
The reservation calendar costs nothing and works fully offline — no feature roulette, 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, and several buildings on one board. Try it free for 14 days.
At a glance
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
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
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
Tap a night, name the guest, save. Track who’s paid, who arrives today, and what each room earns this month.
Work together
Share a building’s calendar with a co-host or cleaner (Premium) — they see it, or even edit it, on their own Apple Account, free of charge. Changes land on both boards in moments, and the housekeeping list covers shared calendars too.
Thirty seconds
The real app, unedited: the board, today’s arrivals, the month’s numbers, calendar import — and a booking typed in seconds.
Straight from the app

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, and adding new buildings or calendar feeds needs Premium again.

Questions
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, and multiple buildings — with a 14-day free trial.
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.
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.
Yes — paste the calendar (iCal) link from your listing and those bookings appear on the board, read-only, refreshed when you open the app (Premium). Exporting your own calendar as an .ics file is free.
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.
Premium sync runs through your own iCloud: sign in with the same Apple ID on each device, and a booking added on your phone shows up on your Mac within seconds. For a co-host or cleaner with a different Apple Account, use calendar sharing — see the next question.
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.
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.
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. External OTA bookings return when their feeds sync again. Your bookings are never held hostage.
English, Polish, German, Spanish, French, Italian, Portuguese, Dutch, Czech, Slovak and Ukrainian — 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).
