InnGrid

The reservation calendar for small lodging — guesthouses, B&Bs, cottages, agritourism.

The calendar is free, forever. No trial countdown, no per-room pricing. You only pay if you want iCloud backup & sync.

• A month of occupancy at a glance. Rooms × days board, today-centred, smooth to scroll and zoom — built to be read in the doorway with one hand.
• Double-booking is impossible to miss. InnGrid refuses overlapping confirmed reservations and makes every conflict loud and visible.
• Works fully offline — your data stays yours. Everything lives on your iPhone or iPad. No account, no sign-up, no server.
