Best free AI workout apps in 2026 (what is actually free, and what is a 7-day trial)

Disclosure: I'm the developer of GoldLift, one of the apps compared here. Competitor facts are from their own listings and reviews, dated below, and I list where they beat GoldLift.

Quick answer: Most "AI workout apps" are trials, not free apps. In October 2026 the only app on this list that is fully free and generates your programme with AI and lets you chat with a coach is GoldLift (iOS, Android coming). Hevy and Strong are excellent free loggers but have no AI. Fitbod has the most mature workout-generation algorithm but costs about $15.99/month after a 7-day trial. JEFIT and Freeletics are free to download with paid tiers that unlock the real product.

Prices checked 23 October 2026, US App Store unless stated. Regional prices differ.

The list

1. GoldLift: free AI coach for gym training

Onboarding takes about three minutes: goal, level, training days, equipment, where you train. The AI builds a programme, and from then on every set carries a weight and rep prescription based on your last session. Rex, the coach, lives in a chat you can open mid-workout; ask about rest, a swap, a deload, or just "should I go heavier?". Twelve coaching personalities if the default one is not your style.

Around that core: a full logger (warm-ups, RPE/RIR, drop sets, rest-pause, cardio), progress charts with PRs and volume, nutrition (meals by photo or text, macros, water, supplement reminders), XP, levels, streaks, quests and trophies, and a social layer with friends, squads, weekly squad battles and leagues. Offline logging, Apple Health and Apple Watch with live heart rate.

Downsides: iOS only for now, young app from a small team in Belgium, Gym Passport check-ins only work at Belgian gyms.

2. Hevy: the best free pure logger

If you already have a programme, Hevy is the fastest way to log it and has a good social feed and a web app. Pro is cheap. No AI, no nutrition, no gamification.

3. Strong: minimalist and dependable

Strong does one thing well and has for years. The free tier is limited to three routines, PRO unlocks the rest. No AI, no social.

4. Fitbod: best algorithm, highest price

Fitbod's muscle-recovery model generates each session from what you trained recently and what equipment you have. It is excellent and it is not free: 7-day trial, then roughly $96 a year. No chat coach, no gamification, no nutrition.

5. JEFIT: biggest library

Over a thousand exercises with animations and a huge archive of community routines. Free tier is ad-supported according to most reviews; Elite unlocks expert plans, advanced stats and watch support.

6. Freeletics: AI coach for bodyweight and HIIT

Great if you train without equipment or run. Not built for barbell training; no set-by-set weight logging worth the name.
