At 3 a.m. you don't want a dashboard. You want one answer: when should they sleep next? Fönster calculates the next sleep window instantly — from age and your own logs, using the age range as a starting point. Didn't fall asleep? One tap recalculates a new window on the spot. No rigid sleep schedule to set up — the wake window is the schedule, tuned to your baby's own bedtime rhythm. A baby tracker that answers instead of asking. No forms. No waiting days. ON YOUR LOCK SCREEN The next window sits on your Lock Screen and Home Screen — you don't even open the app. The countdown updates itself, and when the other parent starts a sleep, your widget says who did it. No notification. Nothing that wakes anyone. BUILT FOR TWO Invite the other parent with a link — no account needed. You see the same log instantly, and either of you can start and end a sleep without "another user" errors. The second caregiver is always included at no extra cost. Grandma can have read-only mode. YOUR DATA IS YOURS Everything lives on your phone first. Export (CSV) works even without a subscription. We never hold old data hostage. No account to create. No ads. LOG ONE-HANDED Sleep, breastfeeding or bottle, diapers and naps with big buttons, in dark mode — built for nights. Logging is free forever — sleep, feeds, diapers, sharing and export. What you pay for is the calculation: the next sleep window and the recalculation when they don't settle. Your first personalized sleep window is included. After that preview it becomes a subscription: $39.99/year or $7.99/month. The yearly plan starts with a 14-day free trial, then renews automatically unless you cancel in the App Store. Fönster gives general guidance from age and your own logs. It is not medical advice — talk to your pediatrician if you are worried.

Verdict
The clearest difference is in-app purchases: OH,YOGA at none against Fönster's 2. OH,YOGA also leads on device support (3 vs 1) and iOS requirement (13.4 vs 16.4). Fönster's advantage is ads (none vs shown) and update cadence (weekly vs fortnightly). On price there is nothing between them.
