Healnest — an all-in-one workout & health tracker for iPhone (offline, no account)

Healnest is an iOS app that combines workout logging with the rest of your health

data in one place, fully offline.

Workout features:

- Exercise library organized by muscle group with per-exercise guides

- Set/rep logging and a built-in rest timer

- Live Activity on the Lock Screen during a workout

- Estimated calories burned, history and weekly trends

Beyond workouts it also tracks steps, water, calories (barcode scanner), sleep and

body metrics (weight, BMI), and syncs two-way with Apple Health. Everything is stored

locally on the device — no account, no ads, no analytics.

Free to download; an optional Pro tier unlocks the advanced modules.

Question for this community: for logging strength sessions, what features make you

stick with an app long-term vs. abandoning it after a week?
