Hi Product Hunt,

I'm Nasir. I built Trayner for people who lift without a coach and want to know if their form is right.

Most workout apps are a good log. Trayner is a log too, but it also looks at how you lift:

Form Check: film a set on your phone and it scores every rep, measures angles such as squat depth and torso lean, and lists what to fix with cues to try. Ask the coach for a drill, or pin a cue to that lift so it shows every time you train it. It measures the main lifts, including squats, bench press, deadlifts and overhead press.

Next weight: it suggests your next weight from your last session, and your weekly plan adjusts after a short night.

Food: log meals or snap a photo, and it suggests protein after each workout based on what you trained.

Logging, routines, history, PRs and food logging are free with no time limit, and your first 14 days include Pro with no card. Your training log is stored on your phone. Coming from Hevy, Strong, Lyfta or FitNotes? You can import your history.

Comparing apps? There's a side-by-side with Hevy, Strong and Fitbod at trayner.app/compare.

It's on iPhone, iPad, Apple Watch and Android, in English, German and Vietnamese.

One honest note: Live Coach (real-time cues while you lift) is validated on squats; other lifts are still in beta.

I'd love your feedback on two things: which lift should Form Check measure next, and was anything in setup confusing?
