For people who want less software, not more

Thunder stack

Small apps that do one job properly and then get out of your way. The first is a training log for lifters. What gets built after it is your call.

What you can hold us to

Five promises, not five features.

Break one and we have failed

Less, but finished

You will never open one of these and find a half built feature. If it made it in, it works. Everything else got cut.

Obvious on first open

You should never need a tutorial to log a set. If it needs a tour, it is not finished.

Nothing in the way

No ads, no upsell popups, no streak guilt. It opens, does its job, and leaves you alone.

Your data is yours

Your workouts live on your phone and back up only to your own account. Export the lot whenever you like and walk away without losing a thing.

Built to keep

Still working three phones from now. No sudden shutdown, no forced migration, no rewrite that throws away what you built up.

The first one · in development · iPhone

Up Lift

Strength training for iPhone.

A strength log that respects your time.

Open it between sets, log the set, put the phone down. It remembers what you lifted last time so you never have to scroll back through a spreadsheet mid workout.

Nothing after this is decided

What should exist that doesn't?

A feature missing from the training log, or a problem nothing solves properly yet. There is no roadmap past this first app, so the next one is genuinely open.
