Head-to-head
Hevy vs Strong: which one in 2026?
Hevy is a workout logging app from Hevy Studios, S.L. with a free tier, a paid Pro tier and a coach-facing product for personal trainers. Strong is a workout tracker from Strong Fitness PTE Ltd. with a free account and a Strong PRO upgrade. Neither one describes its guidance as artificial intelligence on the pages read.
Verdict
Hevy is the easier call on cost, since its Pro tiers are listed and a lifetime purchase ends renewals, and it adds a trainer product. Strong is the better fit for a lifter on an iPhone and Apple Watch who wants RPE, a warm-up calculator and exports. Strong's App Store page lists more than one price for the same period, so confirm the amount before buying. Both leave out AI claims and training-use statements.
Hevy and Strong side by side
| Hevy | Strong | |
|---|---|---|
| Price entry | $0 (free plan) | Free forever (Strong Accounts) |
| Which limits hit free users? | Four routines and seven custom exercises on the free plan, and Pro removes both caps. | The homepage says Strong Accounts are free forever. Limits on routines or history were not shown on the pages read. |
| What does the upgrade cost? | Pro is $2.99 a month, $23.99 a year or $74.99 once, per the vendor's pricing comparison page read in an earlier check. | The App Store lists PRO at $4.99 a month or $29.99 a year, with $23.99 also shown, and lifetime at both $99.99 and $79.99. |
| Which device is supported? | iOS and Android phones. A smartwatch appears in the product imagery, but the pages do not describe how the integration works. | iPhone, Android and Apple Watch, with Apple Health and Siri Shortcuts named on the homepage feature list. |
| What logging tools are named? | Routine planning and progress tracking, plus workout sharing with friends that even free users can use. | Supersets, a warm-up calculator, RPE, custom timers, custom exercises, advanced charts and CSV export are all listed. |
| Is there anything like a coach? | A Trainer in Pro builds plans and gives ongoing guidance, which the vendor calls adaptive programming. Hevy Coach lets personal trainers assign programs to clients. | No coaching product or plan-building feature appears on the pages read. PRO shows best sets, max 1RM and body fat percentage. |
| Can developers reach the data? | A public API with developer documentation is linked from the product page, though the pages do not state the access terms. | Export is available: CSV export is listed and the homepage says data can be exported any time. No public API was named. |
| How long is data kept? | The privacy text sits behind an external iubenda link that could not be read. The pages read show only a two-year figure for analytics cookies. | Two lines conflict. The policy says data is retained indefinitely and also that personal data is deleted when the account closes. |
| Where is the maker based? | The copyright line names Hevy Studios, S.L., and no country or address appears on the pages read. | The privacy policy names Strong Fitness PTE Ltd. and stores data on servers in the United States and other countries. |

Frequently asked questions
Does Hevy or Strong use AI?
Neither describes AI on the pages read. Hevy's Trainer builds plans, but the vendor calls it adaptive programming and not AI. Strong's pages and privacy policy name no AI or machine learning feature at all, so the policy does not address AI processing of workout data. Treat both as loggers with analytics.
Why does Strong show several prices for PRO?
The App Store page lists PRO at $4.99 a month or $29.99 a year in its description, then shows annual entries at $29.99 and $23.99 and lifetime at $99.99 and $79.99. The page notes prices are for US customers and can vary, so check the in-app price.
Which is cheaper over three years?
On the figures read, Hevy's yearly Pro at $23.99 comes to $71.97 over three years, a little under its $74.99 lifetime fee. Strong's price depends on which App Store entry applies, from $23.99 a year to $29.99, so the gap is small. Verify current prices in each app.
Can I get my workout history out of each app?
Strong says you can export your data any time and lists CSV export among its features. Hevy links a public API with developer documentation, but the pages read do not describe a file export. Neither pack confirmed the steps, so test an export during the trial before committing.
