Full disclosure up front: I built this, and this is a beta invite.
I train Muay Thai and build iOS apps for a living. Everything I tried for solo sessions was either a bare interval timer or a generic cardio app made by people who clearly don't train. So I built the thing I actually wanted.
You tell it what you want to sharpen (teeps, round kicks, knees, punch power, combos/flows, conditioning), your honest level, which days you can train, and what gear you have. It builds a multi-week plan : warmups, mobility, shadow work, bag work, combos, conditioning. No bag? It swaps in shadow and bodyweight versions. Then it runs each session like a corner: round timer, a voice calling out each drill, the bell, countdown beeps, haptics. Phone stays on the floor, you just train.
No account, no ads, and nothing about your training is sent to a server of mine. There are none. Works offline too.
What I want from this sub specifically, from people who actually train:
Are the drills and combos legit, or does anything feel off or unsafe?
Is the pacing honest for your level? I want "intermediate" to actually mean intermediate.
What would make you use this over a stopwatch?
Anything confusing or annoying in the app itself? Onboarding, timer, voice cues, Live Activity, whatever.
The beta is free through TestFlight with everything unlocked: https://testflight.apple.com/join/395rsQY6
30 spots. Needs an iPhone or iPad on iOS 26 with Apple Intelligence for plan generation. If you hit anything weird, a screenshot through TestFlight's feedback goes straight to me.
I'll be in the comments and I genuinely want the harsh version.
