Best Free Strength Training Apps in 2026
Almost every workout app calls itself free. The real question is what the free tier actually does, and where the paywall sits once you train seriously. Here is an honest look for lifters who care about strength, not just logging reps.
What "free" really means in workout apps
Most strength apps run a freemium model. You get a capable free logbook, then pay to unlock unlimited routines, full history, advanced analytics, or programming. That is a fair deal, and several free tiers are genuinely good. The catch is that the features serious lifters want most, structured programming and progression, are usually the ones behind the upgrade. So "free" can mean very different things depending on how you train.
The short list
| App | Free tier is best for | Where it charges |
|---|---|---|
| Ægir Iron | Strength-sport athletes who want full programming and analytics free | Only coaches who run a roster |
| Hevy | Fast, polished everyday logging | Pro unlocks unlimited routines and full history |
| Strong | Simple, reliable set tracking | Pro unlocks unlimited custom workouts and extras |
| Boostcamp | Running well-known free program templates | Custom program builder and premium features |
Free tiers and pricing reflect public information at the time of writing and change often. Check each app for the latest.
Ægir Iron
Built specifically for strength sports. Individual lifters get the full platform free with no time limit and no card: RPE and percentage-of-1RM programming, real Cycle, Block, Week, Day periodization, auto-progression, meet planning, competition scoring (Wilks, DOTS, IPF GL, Sinclair), load and intensity analytics (ACWR with an EWMA companion, % of 1RM zones, make rate), Strava sharing with an auto muscle map, and a 400+ movement library with form guides. Only coaches who manage a roster pay, and the athletes they coach train free too. If you want structure rather than just a logbook, this is the free option built for you.
Hevy
One of the most popular loggers for good reason. It is fast, clean, and pleasant, with a large exercise library and good video demos. The free tier covers everyday logging well. Pro unlocks unlimited routines, full history, and more custom exercises. A great pick if a smooth logbook is mostly what you want.
Strong
A long-standing, no-nonsense tracker that does the basics reliably. The free version handles set logging cleanly, with Pro adding unlimited custom workouts and extra features. Good if you value simplicity over deep programming.
Boostcamp
Known for offering popular free program templates you can follow as written, which is handy if you just want a proven plan. Custom program building and some features sit behind a premium tier.
Why Ægir Iron stays free for solo lifters
The model behind Ægir Iron (also written Aegir Iron) is simple: individual training is free, forever, with no feature held back. We only charge coaches for the roster tools that run a coaching business, and athletes on a coach's roster also train free. That means a powerlifter, weightlifter, or strongman competitor can run a fully periodized program, loaded by RPE or percentages, with meet planning and never hit a paywall. For most lifters, that is the difference between a free logbook and a free training system.
