About this app

Hejje is a fitness tracker that keeps your training unreadable to everyone but you.

Record a run, log a set, note what you ate, step on the scales. Everything you put in is sealed on your device before it goes anywhere, with a key only you hold. Our server stores ciphertext it cannot open.

TRACK EVERY SESSION
Record walks, runs, hikes and rides with GPS. See the route on the map, your pace kilometre by kilometre, the climb you did and your heart rate across the session. Recording survives a locked screen and a killed app, so a long run is not lost to whatever your phone decides to do.

LOG YOUR LIFTS
A catalogue of 750 exercises, searchable offline. Log sets, reps and weight, watch your estimated 1RM climb lift by lift, and check your muscle balance so leg day does not quietly disappear.

COUNT WHAT YOU EAT
A food catalogue of more than 13,000 items is built in, so logging a meal needs no lookup and no signal. Set a daily calorie and protein target and see what is still left, rather than only what is gone. Track water against a daily goal, and weight against a trend line that sees through the day to day noise.

SEE THE PATTERN
Steps counted quietly in the background. Day and week streaks, with a calendar that fills in as you train. Personal bests, weekly totals, and progress charts across training, strength and nutrition.

ASK KAYA
An assistant for questions about your own training. How far did I run this month. Am I on a streak. How many sets did I do this week. It answers on your device, so nothing leaves your phone to get an answer.

BUILT TO BE PRIVATE
Your vault is encrypted end to end, with a key derived on your phone.
Setting up asks for a first name. No email address, no password, no phone number.
No ads, no trackers, no analytics SDKs.
The whole app runs from a local database, so it works in a tunnel, on a plane, or with the radio switched off.
No background location permission. Hejje sees where you are while you are recording, and not otherwise.

ALSO INSIDE
Home screen widgets for your day and your streak
Photos and videos attached to an activity

Metric or imperial, light or dark
Sync across your devices, still encrypted

Your recovery key is the only way back into your vault if you lose your phone. Write it down when Hejje shows it to you. We cannot reset it for you, and that is the point.
