What it does
Clue predicts periods from your own cycle length and flow, and takes 200+ symptoms to log against them — cramps, energy, mood, skin, sleep — so a bad week can be read against where you were in the cycle. Berlin-based, under GDPR. From 5 apps that keep the clues to feeling off in separate places.
Alternatives to Clue
The closest alternatives to Clue are AutoSleep, MigrainePal, Medisafe and Welltory — 4 apps from the list Clue appears on, “5 apps that keep the clues to feeling off in separate places”, each answering the same moment a different way.
AutoSleepAutoSleep tracks sleep from the Apple Watch with no buttons to press — the Watch app is optional. Duration, a sleep bank balance, heart rate and Apple's sleep stages, with no analytics, no ads and no upload. Paid once.
MigrainePalMigrainePal opens an attack with one tap and the start time; put the phone face-down and add pain level, aura and notes later. The calendar lays weeks and months side by side, in something you can show a neurologist.
MedisafeMedisafe is the pill reminder, with drug-to-drug interaction warnings and prescriptions imported through Health Records from 100+ US hospital systems. Whether a dose was taken, and when, is the first thing a doctor asks.
WelltoryWelltory reads heart rate variability from the phone camera or an Apple Watch and turns it into a stress and energy reading. Fatigue and burnout tend to show up here before they show up anywhere else.
