Notch is a free, private gym workout tracker. Built for lifters who just want to log a session, see their progress, and move on with their day. One thing. Done well. Log sets and reps. See your progression. That's it. No social feed, no streaks chasing you, no badges to collect, no plan recommending what you should bench tomorrow. Your data stays on your phone. No account to sign up for. No cloud sync. No analytics. No tracking. Notch makes zero network calls. The only thing that ever leaves your phone is what you choose to export. Free. Forever. No catch.
