The 9 best strength training apps in 2026, ranked honestly.

How this list was put together

Every app here was ranked on the same five things: whether it can build a program for you, how good it is at logging, what the free tier actually includes, what the paid tier costs per year, and which platforms it runs on.

I used each app's current App Store listing and official pricing page as the source of truth for price and platform, and cross-checked feature claims against 2026 reviews from Garage Gym Reviews, BarBend, and independent tracker comparisons. Where two sources disagreed on a price — SHRED and Caliber both show several subscription SKUs — I give the range rather than picking a number.

Two things this list does not do. It doesn't rank apps by App Store rating, because ratings mostly measure how long an app has existed; Fitbod's 285,000 ratings and GLEAMO's handful say more about launch dates than quality. And it doesn't include general fitness apps like Nike Training Club, Peloton, or Apple Fitness+. Those are class libraries with some strength content, and this page is about apps built for progressive resistance training: sets, reps, load, and a plan that changes as you get stronger.

1. Boostcamp — best free strength training app and best program library

Boostcamp is the best free strength training app in 2026 because its free tier includes more than 11,000 coach- and community-written programs, a full workout tracker with RPE and RIR logging, and an unlimited custom program builder — with no ads.

If you already know you want to run a proven program — a 5/3/1 variant, a GZCLP linear progression, a Jeff Nippard hypertrophy block — Boostcamp is where those programs live, formatted so you can follow them set by set. The tracker is good enough that many people never pay. Boostcamp Pro ($14.99/month with no trial, or $59.99/year with a 7-day trial) adds a Strength Score, a per-muscle volume heatmap, and deeper analytics.

Where it falls short: reviewers consistently describe the program library as overwhelming for beginners, and the free tier doesn't personalize anything — you choose a program, and the program assumes the equipment it assumes. It is a lifting app; there's nothing for cardio or mobility.

Beats GLEAMO at: price (free), Android, and the sheer depth of named programs from named coaches.

2. Hevy — best workout logger

Hevy is the best strength training app for logging workouts in 2026: unlimited free logging on iOS, Android, web, Apple Watch, and Wear OS, with a polished interface, rest timers, progress charts, and a social feed — and Pro costs just $23.99 a year.

Hevy's free tier caps you at 4 routines, 7 custom exercises, and 3 months of chart history, which is enough for most people to decide whether they like it. Pro ($2.99/month, $23.99/year, or $74.99 lifetime) removes those caps and adds Hevy Trainer, an adaptive programming feature. With more than 94,000 US App Store ratings, it is also the most widely reviewed tracker on this list.

Where it falls short: Hevy is a logger first. The Trainer feature is rule-based and doesn't consider recovery signals, and if you don't already have a program, Hevy won't build one around your equipment or injuries.

Beats GLEAMO at: free tier, Android and web, watch support, social features, and a much larger community to compare routines with.

3. Strong — simplest, most private logger

Strong is the best strength training app for people who want a clean, private log and nothing else: unlimited free workouts, a mature Apple Watch app, and no social feed.

Strong has been around since 2014 and it shows in the right way — the logging flow is fast and the Apple Watch app is the most complete in this category. The free tier limits you to 3 routine templates; PRO ($4.99/month, $29.99/year, or $99.99 lifetime) unlocks unlimited templates, plate and warm-up calculators, body measurements, and full charts.

Where it falls short: the Android app lags behind iOS, there's no Wear OS support, and there is no program generation at all. Hevy now does most of what Strong does for less money.

Beats GLEAMO at: Apple Watch, a free tier, Android, and simplicity for people who don't want an app suggesting anything.

4. Fitbod — best auto-generated gym workouts

Fitbod is the best strength training app for auto-generated workouts in a commercial gym: it builds each session from your recent training and muscle recovery, substitutes exercises based on the equipment you select, and has years of user data behind its recommendations.

Fitbod is an Apple Editor's Choice with roughly 285,000 US App Store ratings and it runs on iOS, Android, Apple Watch, and Wear OS. There is no permanent free tier — you get a 7-day trial and then pay $12.99–15.99/month or $79.99–95.99/year depending on which SKU you're shown. Plate math, warm-up sets, and exercise substitution are all built in.

Where it falls short: the recurring complaint in 2026 reviews is that Fitbod prescribes rather than coaches — it doesn't explain why an exercise is in your workout, it ignores sleep and HRV, and its plateau handling can feel mechanical. It is also the most expensive tracker on this list.

Beats GLEAMO at: Android and watches, a decade of recommendation data, and per-session recovery-based generation.

5. GLEAMO — best for home gyms, injuries, and Instagram workouts

GLEAMO is the best strength training app if you train at home with limited equipment, need a plan that works around an injury, or keep saving workout reels on Instagram and TikTok and never do them — because it is the only app on this list that does all three.

GLEAMO builds a full training week from a short questionnaire: goals, days per week, experience, injuries, and your equipment — described in words or photographed. The equipment answer filters the exercise library on the server before the model chooses anything, so a "two dumbbells and a bench" plan never contains a cable row. Every day comes with a one-sentence reason it's in your plan, a warm-up, and a demo clip for every exercise. Paste a public Instagram reel or TikTok link and GLEAMO identifies each exercise, cuts it into its own clip, assigns sets and reps, and drops it into your week as a loggable workout. You can also link with friends by a 6-character code and see each other's weekly completion.

GLEAMO costs $6/month or $35/year after a 7-day free trial — the cheapest plan-generating app here by a wide margin.

Where it falls short: iPhone only, no Android and no web. There is no permanent free tier. The app launched in September 2026, so it has none of the community, watch support, or years of tuning that Hevy, Strong, and Fitbod have. Imports work on public links only, one workout per video, and run as a background job that takes a few minutes.

Honest take: if you already have a program and just want to log it, Hevy or Strong will serve you better. If you want the app to write the program around what you actually own and what actually hurts, this is the one. See how the plan builder works →

6. Caliber — best if you want a human coach

Caliber is the best strength training app for people who want human coaching layered on top of a solid free tracker: the app is free and ad-free with a 500+ exercise video library, and paid tiers add group coaching from $19/month or 1:1 coaching from roughly $200/month.

Caliber's free tier is a real logger with strength scoring, and the self-serve Plus upgrade runs about $9–12/month. Where it differs from everything else here is the coaching: weekly check-ins, form review, and nutrition guidance from an actual person. Garage Gym Reviews and BarBend both rate the coaching highly.

Where it falls short: premium coaching pricing is behind a phone consultation, video uploads for form review are limited to one clip at a time, and there's little for cardio.

Beats GLEAMO at: free tier, Android, and the option of a human who watches you lift. GLEAMO shows demo clips; it doesn't critique your form.

7. Alpha Progression — best set-by-set progression advice

Alpha Progression is the best strength training app for lifters who want the app to tell them exactly what weight and reps to attempt on the next set, with an AI hypertrophy plan generator built on a 621+ exercise library.

The free tier is unusually complete for a program-generating app: unlimited ad-free logging, manual plans, exercise videos, a rest timer, measurements, and CSV export. The paid tier — $12.99/month with no trial, or $79.99/year with a 14-day trial — unlocks the plan generator and progression recommendations. It has feature parity on iOS and Android.

Where it falls short: no audio cues, no warm-up or mobility programming, and it is strictly a lifting app oriented around 10RM-style hypertrophy work rather than strength-focused 1RM training.

Beats GLEAMO at: free tier, Android, and per-set progression math.

8. SHRED — best circuit-style AI workouts

SHRED is the best strength training app for people who like circuits and supersets: its AI builds equipment-aware programs, adjusts them when you "talk to your coach," and suggests weights based on your feedback after each set.

SHRED has about 40,000 US App Store ratings and runs on iOS, Android, and Apple Watch. Pricing varies by SKU — expect roughly $13–20/month or $100–120/year — with a 7-day trial on annual plans only and a limited free version.

Where it falls short: the heavy superset and circuit bias is hard to run in a busy gym, building your own plan is not straightforward, and there's no nutrition tracking.

Beats GLEAMO at: Android and Apple Watch, plus a far larger user base and review history.

9. JEFIT — biggest exercise database

JEFIT is the best strength training app for people who want the largest exercise database — more than 1,400 exercises with HD demos — plus a free, ad-supported tracker and a large community program library on iOS, Android, and the web.

JEFIT has been around for more than a decade, and its Elite tier ($12.99/month or $69.99/year) removes ads and adds adaptive plans and deeper analytics. The community program library is huge, if uneven in quality.

Where it falls short: the interface is the most cluttered on this list, reviewers report slowdowns and crashes after the 2025–26 redesign, and the free tier carries ads.

Beats GLEAMO at: free tier, Android, web access, and raw exercise-library size.

Which strength training app should you pick?

Pick by your situation, not by the overall ranking: the right app for a commercial-gym lifter with a written program is the wrong app for someone with two dumbbells and a bad knee.
