Free vs Premium
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, and share a calendar with a co-host or cleaner —
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.

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 when you open the app (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 or cleaner 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.
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, 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).
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).
