Fitless
Our appBest for: people who want the AI to build and progress the workout, for free
Fitless is an AI personal trainer for iPhone and Android. It builds your training plan from a quick quiz and a photo-based analysis of your body (body-fat percentage, lean mass, and body type), adapts exercises to the equipment you have, and logs every set. As your history grows, the AI detects when you are ready to progress and suggests the next load right on the workout screen.
It also imports existing plans: record your screen in another app, or send a photo of your gym sheet, a PDF, or a spreadsheet, and the AI rebuilds the full plan. There is an Apple Watch app with exercise GIFs, offline mode, streaks, and a weekly ranking with friends. During launch, it is 100% free, no credit card required.
Strengths
- Builds and progresses the workout for you, based on your body and equipment
- Photo-based body analysis included
- Imports gym sheets, PDFs, spreadsheets, or video from other apps
- Free during launch, with no workout limits
Weaknesses
- Newer app with a still-small community
- No desktop web version
Fitbod
Best for: people who want a veteran algorithm and accept a subscription
Fitbod is one of the most established workout-generation apps in the world. Its algorithm builds sessions around muscle recovery: it tracks which groups you trained and suggests the next workout to balance volume and rest. The exercise library is large, with well-produced videos, and the interface is available in English, Spanish, and Portuguese.
The catch is price: US$ 15.99 per month or US$ 95.99 per year in the US as of July 2026 (recently increased from US$ 12.99/79.99), with a 7-day free trial. There is no photo-based body analysis and no plan import.
Strengths
- Muscle-recovery algorithm refined over many years
- Extensive exercise library with videos
- Deep Apple Health and Apple Watch integration
Weaknesses
- US$ 15.99/month with no permanent free plan
- No plan import and no body analysis
Hevy
Best for: people who already have a plan and want the best free manual tracker
Hevy does not build the workout for you: it is a tracker. You create your routines (or copy a friend's) and log sets, loads, and reps with one of the fastest interfaces in the category. The free plan is generous, with unlimited workout logging, and its social feed is the most active among tracking apps.
Hevy Pro (between US$ 2.99 and 4.99 per month depending on region, with a lifetime option) unlocks unlimited routines, full chart history, and extra tools. If you already know exactly what to train and just want the best digital clipboard, Hevy is hard to beat.
Strengths
- Fast, well-designed set logging
- Generous free plan
- Large community and social feed
Weaknesses
- Does not generate or build the plan for you
- No body analysis and no photo/PDF import
Strong
Best for: people who want the most minimalist tracker possible
Strong is one of the oldest and most reliable lifting trackers. The proposition is the same as Hevy's (you build, it logs), focused on simplicity and stability. The free plan is limited to 3 saved routines; Pro costs about US$ 4.99 per month, with a lifetime option. There is no AI workout generation and no meaningful social layer. It is the pick for people who want minimum friction and nothing beyond logging.
Strengths
- Simple, stable, and to the point
- Years of reputation in the category
Weaknesses
- Only 3 routines on the free plan
- No AI, no social, no import
Freeletics
Best for: guided no-equipment training (bodyweight and HIIT)
Freeletics uses AI to build plans focused on bodyweight training and HIIT, with video- and audio-guided sessions and an Apple Watch app that follows the intervals. It is a great entry point for people who train at home with no equipment and prefer ready-made sessions to managing sets and loads. The Coach runs on an annual subscription (check the official site for pricing in your region). For strength training with load progression, it is not the app's focus.
Strengths
- Video- and audio-guided sessions
- AI plans for no-equipment training
Weaknesses
- Coach requires the paid subscription
- Not focused on strength training with loads
Nike Training Club
Best for: 100% free guided classes
Nike Training Club is completely free and offers hundreds of video classes for functional training, bodyweight strength, mobility, and yoga, with an Apple Watch app. It does not build a personalized AI plan and does not log loads per set, so it does not replace a lifting app. As a free complement for cardio and mobility days, it is unbeatable on price.
Strengths
- 100% free, no subscription
- Well-produced video classes
Weaknesses
- No personalized AI plan
- No per-set load logging
How to pick the right workout app?
Want the app to build and progress the workout for you, without paying: Fitless. Prefer a veteran algorithm and do not mind the US$ 15.99/month subscription: Fitbod. Already have your own plan and just want to log sets with a great social interface: Hevy. Want the most minimalist logging possible: Strong. Train at home with no equipment and prefer guided classes: Freeletics or Nike Training Club.
Frequently asked questions
What is the best free AI workout app?
In 2026, Fitless is the only app on this list that generates complete workouts with AI without charging a subscription: during launch, every feature (workout generation, body analysis, plan import, and Apple Watch) is free. Nike Training Club is also free, but it offers ready-made video classes, without a personalized plan or load logging.
Can an AI workout app replace a personal trainer?
For most people who train without supervision, an AI app covers the essentials: building the plan, adjusting loads, and keeping progression on track. An in-person trainer remains superior for detailed technique correction, injury rehab, and high-performance athletes. The two can coexist: many users log and progress their training in the app and review it with a professional.
What is the best app for training at home?
If you have dumbbells or bands, Fitless adapts the plan to your equipment and keeps load progression going. If you have no equipment at all and prefer guided video sessions, Freeletics (paid) and Nike Training Club (free) are the best options.
