Harson.ai is the software studio of Harson Group Pty Ltd — a registered Australian company, not a hobby account. One app is live on Google Play. The other is in testing. Both are small, sharp tools for real life: no feed, no ads, no account required to use what you paid for.
Live on Google Play
A household gym logger for people who train in a garage, not a chrome commercial gym. You tick what you actually own, and the session is built around that shed — and around the people in it.
No social feed. No kids' leaderboard. Not a medical device. Just the work, the house, and the week.
In testing
A rifle ballistics calculator for hunters and long-range shooters. Set up your rifle, scope and load once; every solution after that runs on the phone — no signal, no account. The solver is validated against an independent reference to within 0.001 mil.
Reticles are drawn as real vector geometry from the manufacturers' own spec sheets, and the app tells you which ones have been checked and which are still awaiting a second look.
If an app needs a signal to do its main job, it is broken in the places these apps get used — a shed, a hide, a range with no reception. Save your setup once and it works with the phone in flight mode.
Harson Ballistics labels every reticle and every bullet with where the figure came from and whether anyone has double-checked it. A number that looks authoritative and is wrong is worse than one that says it is unconfirmed.
No account to use the app. Nothing sold, nothing shared. Garage Gym syncs a household because that is the point of it; Harson Ballistics sends nothing at all.
Written on the Sunshine Coast by one person who uses both apps every week. Email goes to a human, usually the one who wrote the code.
