HyperMass
Strength training that stays on your phone.
A strength-training app with an 850+ exercise library, real routine building and honest progress tracking — with no account to create and nothing sent anywhere.
Not yet released · iOS and Android
What it will be
Most training apps are a login wrapped around someone else's database. HyperMass keeps every set, every routine and every measurement in a database on your phone.
There is no account because there is no server. No analytics, no crash reporting, no advertising identifier, no third-party trackers. Nothing about your training is transmitted, because there is nowhere for it to go — and you can export the whole history to a file you keep, at any time.
It is being built by Red Spectrum LLC. There is no waitlist and no email capture: collecting your address to announce a privacy app would be a strange way to begin.

Planned at launch
An exercise library that earns its size
850+ exercises with rendered art, searchable and filterable by the muscles they train.
Routines you build, not plans you rent
Compose your own or start from a template, and edit mid-workout without losing the session.
Logging that keeps up
Supersets, RPE per set, rest timers, plate loadouts and warm-up ramps.
Progress you can read
History, a calendar planner, and a muscle heat map of what you have actually trained.
Your data stays yours
Full backup export and import. Optional Apple Health and Health Connect sync.
No subscription for your own history
Pricing is not finalised, but your training log will never sit behind a renewal.
