Best offline health diary for iPhone
What “best” means here
Best here means bedside-shaped: one-handed entry in the dark, a flare-mode timer, nothing needing typing, and no signal needed.
Not for: keeping the record on more than one phone.
Endonem is an iPhone record for endometriosis built for bedside moments. One-handed entry in the dark, a flare-mode timer in five big steps, one decision per screen with no typing, and a calm empty-state square meet a sealed, dated report you print for visits. The app has no networking code at all.
Verdict: the bedside test is simple. When pain spikes at night you can still log one-handed in the dark, run the five-step flare timer, answer one choice per screen, and trust a single violet shade to hold severity. No signal is needed because the app has no networking code at all.

Endonem is a record, not a diagnosis. It does not detect, diagnose, treat, cure or prevent endometriosis or any other condition, and nothing in it is medical advice.
FAQ
Can I log one-handed in the dark?
Yes. One-handed, in the dark, in under a minute, with one decision per screen and nothing needing typing.
What happens in flare mode?
Flare mode is a timer, five big steps, and nothing else. It runs one-handed in the dark.
Do I need to type or catch up?
No typing. Nothing in the intake needs typing and each screen asks one decision. If you miss a day, today's square is waiting with no pressure and no streaks.
How do I show how bad it is?
Pick a violet shade, light to dark. It is one hue only, never red-to-green, because a 3 on a bad week is not a green day.
Does bedside logging need a signal?
No signal needed. The app has no networking code at all.
