A gym tracker that works in the basement

Gyms are where signal goes to die

Basements, concrete, steel racks and no windows. It is the one place a fitness app is most likely to be opened and least likely to have a connection, and it is where an app that queries its exercise list from a server becomes a spinner between you and your next set.

Hejje keeps the catalogue on the phone. Searching for an incline dumbbell press is a local database query, so it returns instantly whether you have five bars or none, and nothing about logging a session behaves differently in airplane mode.

What you get per session

• 750 exercises covering barbell, dumbbell, machine, cable and bodyweight work, searchable offline.
• Per-set logging of reps and weight, in metric or imperial, as you go rather than afterwards.
• Estimated 1RM per exercise, charted across sessions so progress is visible over months rather than guessed at.
• Muscle balance for the week, which is the screen that catches leg day quietly disappearing.
• Reusable routines with targets, and a nudge when a session has drifted away from the routine behind it.
• Personal bests and volume totals, all computed on the device from your own history.

Your log is not somebody else's data

Every session is sealed on the device before it syncs, with a key only you hold, and our server stores ciphertext it cannot open. Signing up asks for a first name: no email address, no password, no phone number. There is no advertising network and no analytics SDK in either app.

What is readable on our side is a short and specific list, and there is a third category, the shape of the data, that encryption does not hide. Both are set out in full on the private fitness tracker page.

The rest of your training is in the same app

Lifting apps usually stop at the gym door. Hejje also records walks, runs, hikes and rides with GPS, and logs food from more than 13,000 built-in items with calorie and protein targets, water and weight. One streak, one calendar and one set of weekly totals across all of it.

That combination is the actual argument, and it has a page of its own.
