GymStreak

GymStreak is an AI personal trainer for iPhone, Apple Watch and Android that writes the programme instead of handing you an empty log. Onboarding asks your goal, training days, session length and what equipment you can actually use — a full gym, a few dumbbells, or bodyweight only — then builds a weekly plan that says which days you train, which muscles each session hits, and a matching daily calorie and macro target. Each session lists exercises, sets and reps with the target muscles shown on a body map, a video demo and step-by-step instructions sitting above the set inputs so you can check form between sets. You log weight and reps in kg or lb, tick the set, and the rest timer runs; supersets, warm-up sets and drop sets are built in. The AI coach opens from any screen, answers questions, and can create or edit workouts in your plan — ask it to work around your climbing, for example. Food tracking lives in the same app: log a meal by photo, typed or spoken description, or food search, and see calories, protein, carbs and fat against the targets from your plan. Body weight, measurements, progress photos and weekly stats for volume, sessions and training time round out the progress side. Sets can be logged from the wrist via the Apple Watch app, the rest timer shows as a Live Activity, and weight, workouts and nutrition sync with Apple Health or Google Health Connect. XP, gym ranks from Rookie to GOAT, badges and weekly streaks push consistency — streaks count weeks, not days, so rest days never break them. The app is free to download with a 4.7 App Store rating from 74k ratings worldwide (checked 29 Sep 2026), and it's aimed at beginners to intermediates who want the plan written for them. If you already run 5x5 or a push/pull/legs split and just want a fast logger, Strong or Hevy is the better pick — GymStreak's own comparison says so.
