Forget "when did I last…?" CountWhen gives you instant clarity on anything that runs on intervals — not just dates. One tap to log. Always know how long it's been, when it's due, or how long you still have to wait. PERFECT FOR PARENTS Baby bottle, nap, diaper, feeding, pumping — set it once and CountWhen tracks it all. Know exactly how long since the last feeding, when nap time opens up, or whether it's too soon to give something again. Designed for the tired parent who can't afford to lose track. Baby feeding, bottles & pumping sessions Diaper changes Nap scheduling & sleep training Supplement timing Instrument practice (piano, guitar, violin) Reading time & homework sessions Screen time gaps Sunscreen reapplication Kids' chores & responsibilities THREE EASY WAYS TO TRACK Just tracking — Log events and see patterns over time (no reminders) Due every — Set recurring intervals and get gentle notifications when it's time again Wait at least — Enforce a minimum wait time before logging again (with override option) HOW IT WORKS Set a timer interval in minutes, hours, days, weeks, or months — or use an anchor time. Tap LOG when something happens. CountWhen instantly shows how long it's been, how long until it's due, and whether you still need to wait. Clear progress bars, overdue alerts, and ready notifications keep you on track. WHY NOT JUST USE YOUR CALENDAR? Calendars struggle when elapsed time matters more than a fixed date — like spacing coffee every 2 hours, cleaning the bathroom after 7 days, or adjusting for something that ran late. CountWhen resets from when you last did it, not when you planned to.

Verdict
The clearest difference is in-app purchases: Deep Sleep at none against CountWhen's 1. CountWhen's advantage is update cadence (every 4 days vs every 8 days) and iOS requirement (15.1 vs 18.5). On price, ads and device support there is nothing between them.
