Best Strength-Training Apps: Programming, Workout Logging and Coaching Compared

The best strength training apps do different jobs. Some write the session. Some only log it. This is a source-reviewed guide, not a hands-on lab test. Prices and ratings below were captured on 13 September 2026 unless a page date is older.

Who this best strength training apps shortlist is for

Use this page if you lift at a gym or at home and want a phone to either plan the work or record it. Skip it if you already have a coach who writes every session on paper. Skip it if you only want cardio classes. Those products live elsewhere.

The split is programming versus logging. Ladder and Fitbod sell a plan. Boostcamp and Caliber sell a library plus an optional upgrade. Hevy and Strong sell a fast logger, with Pro unlocking history and extra routines. Garage Gym Reviews’ 2026 workout-app roundup named Boostcamp “Best Workout App Overall,” Fitbod “Best AI Workout App,” Ladder “Best Home Workout App,” and Caliber “Best Workout App for Men.” Those are editor labels from that site, not a lab score.

If you already know you want one product, jump to Hevy, Strong, Boostcamp, or Caliber when those pages go live. The table here is the comparison, not a trophy.

How the six products differ in one view

UK and US money stay in different cells. Store ratings stay in different cells. Install counts are omitted where the store did not show a trustworthy public band in our capture. “Check live” means the listing showed more than one SKU or we lacked a clean sterling page.

Dated store scores, kept apart

Apple US, 13 September 2026: Ladder 4.9 from 194K ratings (version 4.13.0, listed as updated about 14 hours before capture). Fitbod 4.8 from 284K (version 8.33.0, about four days before capture). Hevy 4.9 from 92K. Strong 4.9 from 109K. Boostcamp 4.8 from 10K (version 265, 5 September 2026). Caliber 4.8 from 5.9K.

Apple UK, same research window: Ladder 4.9 from 15K. Fitbod 4.7 from 16K. Strong 4.9 from 24K. Country samples are not interchangeable.

Google Play US: Fitbod 4.5 from 31.1K reviews, listing updated 8 September 2026. Hevy 4.9 from 265K reviews, listing updated 10 September 2026. We did not confirm a Play listing for Ladder’s strength app; a different finance app shares the name. Treat Android Ladder as unverified.

Ladder: pay for a coach in your ear

Ladder Technologies sells weekly plans grouped as “teams,” each with a named coach, in-ear cues, and a journal. The public pricing page, captured 13 September 2026, listed a 7-day trial with no card until it ends, then Pro at $29.99 a month or $179.99 a year. Monthly Pro includes one team and two team changes a month. Annual Pro unlocks all teams and unlimited changes. Apple US also listed higher Elite SKUs up to $49.99 a month. Those are extras, not the default cell above.

Who it fits: people who want someone else to write the week and talk through the session. Who should skip it: Android-first users, and anyone who only needs a spreadsheet. Full dated notes sit in the Ladder review.

Fitbod: an algorithm, not a conversation

Fitbod Inc. builds the next session from the equipment you tick, the time you have, and the sets you logged. The membership checkout at app.fitbod.me showed $15.99 a month or $95.99 a year on 13 September 2026. Help text, via Fitbod’s own subscribe article, says prices vary by region and store, and that a 7-day trial auto-renews unless you cancel. Garage Gym Reviews’ 2026 list called it the best AI workout app and scored the product 3.8/5 on its equipment page. Testers liked equipment matching. They flagged no lasting free planner and Android glitches as limits.

Who it fits: mixed gyms, hotel rooms, and people who hate writing a split. Who should skip it: lifters who already run a named programme and only need a log. See the Fitbod review.

Hevy and Strong: log first, programme later

Hevy’s site, captured 13 September 2026, calls itself a free tracker for iOS and Android with watch and web clients. Apple US IAP listed Pro at $2.99 a month, $23.99 a year, or $74.99 once. Play’s Data safety box said no third-party sharing in that capture. The free tier still caps saved routines. You paste a split from a friend or write your own. That is a feature if you already trust a template. It is a hole if you wanted a coach.

Strong is the older minimal logger. Apple US showed PRO at $4.99 a month, $29.99 a year, or $99.99 Forever, plus leftover SKUs. Apple UK showed sterling PRO around £4.99 a month and about £27–£29 a year, with Forever at £79.99 or £99.99. CNBC and The Verge blurbs still sit on the store page. They are press quotes, not 2026 lab tests. Choose Strong if the screen should disappear. Choose Hevy if you want a feed and a cheaper Pro year.

Boostcamp and Caliber: libraries, then optional humans

Boostcamp’s Pro page, marked updated May 2026, said the 11,000+ programme library and the tracker stay free. Pro is $59.99 a year (advertised as $4.99 a month billed annually) with a 7-day trial, or $14.99 a month with no trial. Extra Pro items include a Strength Score, a per-muscle volume heatmap, and 20+ exclusive coach programmes. Garage Gym Reviews’ 2026 testers liked the named authors (Helms, Wendler, and others) and said video teaching is thin. That matches a product aimed at people who already know a squat.

Caliber’s US App Store listing described a free tracker, Caliber Plus plans, and separate premium 1:1 coaching. Plus IAP on that page included $12 a month and $72 a year. Garage Gym Reviews described group coaching near $19 a month and 1:1 from about $200 a month. Those coaching figures are from that 2026 roundup, not from a checkout we opened. If you want a human on chat, confirm the live coaching invoice. If you want a free log plus videos, the free tier is the product.

Free versus paid, without a fake score

A usable free path exists on Hevy, Strong, Boostcamp, and Caliber. Ladder and Fitbod are trial-then-pay planners. Twelve-month US list costs, using the clearest public annual SKU, run about $24 for Hevy Pro, $30 for Strong PRO, $60 for Boostcamp Pro, $72 for Caliber Plus, $96 for Fitbod, and $180 for Ladder Pro. Monthly paths cost more. UK checkouts differ. Fitbod’s GB listing showed yearly IAP at £70.99 and £99.99. Ladder’s GB listing showed PRO Annual at £89.99. Always believe the screen you are about to tap.

NHS adult guidance still wants muscle-strengthening work on at least two days a week. CDC adult guidance says the same. An app can remind you. It cannot grant the health effect if you skip the sets. For how to raise load without chasing novelty, use our progressive overload guide.

Privacy and evidence, in short

Workout apps store what you lift, and often what you weigh. Fitbod’s privacy policy (updated 18 April 2024) describes profile, workout, HealthKit, and Health Connect data, plus analytics and advertising technologies. Apple’s Fitbod label, captured 13 September 2026, said usage data may be used to track you, and that health and fitness can be linked to you. Hevy’s Play label in the same window claimed no third-party sharing. Those are developer statements, not audits.

We found no peer-reviewed trial that validates Fitbod’s algorithm or Ladder’s teams as a clinical intervention. Progressive overload research sits on sets, reps, and load, not on a particular icon. Treat store stars as sentiment. Treat watts-and-reps history as a diary.
