What's New in HypoMe

3.4.0

September 21, 2026

Your days, counted correctly. HypoMe now starts and ends each day where you actually live — across clock changes, and past midnight — so what you log is what your results report. • Days that line up with your life — they start and end in your own time zone, including the two days a year the clocks change. Reminders, streaks and experiment lengths no longer land an hour out, and a check-in you open late at night stays on the day you opened it. • Apple Health sleep counts toward the day you wake up, not the day you went to bed — and sleep already recorded the old way has been corrected for you. • Results that match what you logged — a fully logged experiment is never reported as cut short, and completeness is measured over the stretch your run actually covered. • Editing an old check-in no longer marks it as logged late. The record reflects when you first saved it, and existing entries have been repaired. • Voice check-in handles a hard moment with care — if what you say touches something HypoMe should not try to answer, it shows crisis resources and stops, instead of asking you to try again. • Crossover designs, fully supported — an A/B/A experiment names and counts every phase, in the schedule, the results and the exported PDF. • Keep going offline — build an experiment, check in and manage your runs with no connection, and Apple Health imports are saved to your device rather than dropped. • Lock Screen and Home Screen widgets stay current as the day turns over, and Siri shortcuts reach the right screen from wherever you are. • Fixed: text now wraps instead of overflowing at the largest accessibility sizes, and returning to a tab no longer stacks a second copy of the app behind it. HypoMe now requires iOS 16.4.

User reviews

Caffeine experiment

Been using this for a few weeks to test if cutting caffeine actually helps my sleep. Easy to set up, quick check-ins, and it actually shows you the results instead of you trying to eyeball it yourself. Simple app that does what it says.

Actually helped me get a clear answer

Used this for 10 days to test whether drinking 1 gallon of water throughout the day actually changed my energy levels. The AI built the experiment for me in about 30 seconds, and the daily check-in took maybe 10 seconds. At the end, I got a clear answer with actual stats, not just a streak number.

I do wish I could rename an experiment after starting it, but overall it made self-tracking much easier than I expected.
