StrengthLog Review 2026: Generous Free Tier, $109 Premium

StrengthLog calls itself “the world's most generous workout tracker – built by lifters, for lifters”, and the free tier is unusually complete. This review uses StrengthLog's own site, terms, help desk and App Store listing as the source for every claim; anything we could not confirm there is marked unverified. We make Strongbro, a competing app, so read the comparison section with that in mind.

What StrengthLog is

StrengthLog is a workout log for iOS and Android, with a web version referenced in its terms. It is made by Styrkelabbet AB of Lund, Sweden, “a small, Sweden-based company of seven people” co-founded by Daniel Richter, Philip Wildenstam and Nils Nordin, who created the app and heads development. It launched on the App Store in November 2018 and is on version 8.1.2, released in May 2026.

The positioning is direct: the homepage headline reads “Free Workout Tracker”, then “For Lifters, By Lifters” and “No ads, no clutter.” The site FAQ says the developer is “giving 90% away in the free version” and claims more than 100,000 monthly users. The US App Store listing shows 4.9 stars on roughly 3,600 ratings.

Logging is manual: tap the + icon, add an exercise, enter the weight and reps, tap the check mark to save. Set types include supersets, dropsets, circuits, Tabata, AMRAP, EMOM and weightlifting complexes.

Pricing as listed

The download is free. On the US App Store, the in-app purchases are:

Subscriptions auto-renew and, per the terms, are tied to your Apple ID or Google account and cannot be transferred between iOS and Android. The site offers a 14-day Premium trial “for a limited time”; the App Store description does not mention one. Premium unlocks the full program catalog, advanced statistics, the muscles-worked map over a period, unlimited goals and streaks, sharing with other users, per-set percentage of 1RM, RPE and reps in reserve, and monthly and yearly training reports. Prices were as displayed on 11 September 2026 and can change.

What is genuinely good

The free tier is real. Unlimited workouts and routines, a 500+ exercise library with unlimited custom exercises, PR tracking, a plate calculator, a rest timer, volume stats, 1RM and warm-up calculators, Apple Health sharing, monthly challenges and no ads. Many trackers cap free workouts; StrengthLog does not. Email support is offered “even for the free version”, with a public help desk.

The program content is deep. Over 200 programs and routines for powerlifting, bodybuilding and general strength, with basic programs free and the full catalog in Premium. The builder is free; Premium adds programming by percentage of 1RM and by RPE or reps in reserve. If you train from a written plan, this is the app's centre of gravity.

Records are handled properly. Personal records for every exercise and rep count, goals for 1RM, volume and workout count, a free 1RM calculator, and per-set estimated 1RM with Premium.

Strength Levels are a thoughtful addition. Since version 8.0 the app shows your Strength Level, from Beginner to Elite, as a percentile against other StrengthLog users on your 15 most-logged exercises. It needs your sex, age and bodyweight and produces a shareable image. It is self-reported app-user data, not a lab standard.

Platform reach. iOS, iPad, Apple Vision, Apple Watch (watchOS 9.0 or later), Android and a web version. Apple Health sharing is one-way: “the app does not receive any data in return.” Android gets Google Fit and Health Connect.

The privacy policy is specific. It names the controller, the Swedish registration number, the supervisory authority and the categories of recipients, which is why the criticisms below can be precise.

What is weak or missing

An account is required. The terms state: “Once the trial period has expired, you need to register a user account to be able to continue to use the Service.” Sign-up is by email, Apple ID, Google or Facebook. The site's reasoning is honest: “Without an account, your workout data would only be saved locally on your phone. With an account, we can keep a copy in the cloud.” Honest, but still a requirement to hand a company your training history to keep using a log.

Deleting your account takes an email. There is an in-app Delete account button, but the help desk says “You'll have to email us about deleting your account, just as a safety measure”. Deletion is then not restorable.

Premium is expensive, and there is no way to buy once. $109.00 a year, or $16.90 a month, with no lifetime option on the US App Store. The jump from a free tier this good to the paid tier is steep, and it never ends.

Logging is manual only. The documented path is tap, type, tap. No voice or camera logging is mentioned on the site, listing or help desk; we mark this as unverified absence, since public documentation is the limit of what we can check.

Languages are limited. The App Store lists English only, and the terms say “The Service is available in Swedish and English.” Whether the interface offers further languages is unverified.

Export is not documented. No export or CSV feature appears on the homepage, App Store description, terms or help desk, and a help desk search for “export” returned nothing. An undocumented export may exist. For an account-based app that stores data centrally, a documented way out is the gap we would most like to see closed.

Offline behaviour is unclear. The terms say use requires Internet access and that server storage happens only when connected. How much you can log with no signal is not stated.

No AI or photo analysis. Progress pictures can be uploaded and measurements logged by hand, but no photo-scoring feature is documented.

Privacy, in the developer's words

Where your data goes is stated plainly in the app privacy policy (version 3.0, updated August 2026): “All data connected to your account is stored on our servers (if – and only if – you use the app connected to the Internet, so that a backup is possible)” and “We use service providers, which also may use sub-contractors, that are established in third countries outside the EU/EEA.” That data includes “logged workouts, workout summaries, personal records, Estimated 1RMs, Strength Levels, connections with other users, participation and progress in challenges” and any “progress pictures that you upload in our App.”

Recipients named include app stores, social login platforms, other users via social features and challenges, opt-in scientific research, partners and IT service providers. The controller is Styrkelabbet AB, registration number 559101-8816, under GDPR with IMY as the supervisory authority.

The App Store privacy card, declared by the developer and “not verified by Apple”, lists data linked to you as name, email address, user ID and crash data, for analytics, product personalisation and app functionality; usage and performance diagnostics are collected but not linked to you. On Apple Health: “we only share the information you request us to share – the app does not receive any data in return”.

None of this is hidden. It is the trade: cloud backup and social features in exchange for a copy of your training history on someone else's servers.

Who StrengthLog suits

• Lifters who follow programs and want the app to hold the plan.
• Anyone on Android, or moving between Android, iPhone and a browser.
• People who want a complete free tier with no ads and will never need Premium.
• Lifters who like a shareable Strength Level percentile against other users.
• Users who want Apple Watch and Apple Health, accepting that the watch app is not documented publicly.

It suits less well anyone who wants no account, voice logging, a language other than English or Swedish, or a documented export.

How it compares to Strongbro

StrengthLog is a program tracker with a manual log attached; Strongbro is a log first, with no program catalog at all.

Strongbro's voice logging turns one spoken sentence into structured sets, in any of 30+ languages, with a review screen before anything saves. Its personal records are detected on every save, for weight at each rep count and estimated 1RM, with no paid tier gating per-set estimates. Data stays on the iPhone with optional iCloud sync, there is no account, and export is built in. It costs $14.99 a year or $19.99 once, after a 3-day trial. It is iPhone only, with no Apple Watch app and no program library.

StrengthLog wins on programs, platforms, the free tier and the size of its rating base. Strongbro wins on logging speed, languages, price and privacy. The full side-by-side, with feature and pricing tables, is in Strongbro vs StrengthLog.

The bottom line

StrengthLog is a serious, well-supported workout log with one of the most complete free tiers in the category and deep program content. Its weaknesses are structural rather than careless: an account after the trial period, server-side storage with processors outside the EU/EEA, English and Swedish only, manual logging, and a $109.00 Premium with no lifetime option. Its privacy policy states all of this plainly, which counts in its favour.

If you train from a program and want a free, ad-free log that runs everywhere, StrengthLog is a strong choice. If you want to log by voice, in your own language, with your data on your own phone, it is not that app, and it does not pretend to be.
