StrengthLog vs Hevy: Which Free Gym Log Should You Use?

It depends on what you need from the free version. StrengthLog's free version logs unlimited workouts and lets you create unlimited custom exercises, and its listing gives no number for free routines. Hevy's stops at 4 routines, 7 custom exercises and 3 months of history, but logs RPE for free and has a public feed, a web app and Wear OS. If you'll pay, Hevy Pro costs $23.99 a year and StrengthLog Premium $109.00 (US App Store, October 2026). You can pay for StrengthLog Premium with a Swedish wellness stipend.

A third option, if you're on iPhone: GainsLog, the app I build, sets a weight and rep target for each set from what you logged, on its free version. According to their help centers, neither StrengthLog nor Hevy sets each session's weight for you without a program you write or a paid plan.

Every StrengthLog and Hevy fact below comes from their US and Swedish App Store listings, StrengthLog's website and both help centers, read on 30 October 2026. In GainsLog's launch post I named StrengthLog's programs as one of the things I wanted in a single app.

StrengthLog's terms come from its US listing, website and help center. Hevy's come from its US listing and help center.

Hevy's free version stops at 4 routines, 7 custom exercises and 3 months of workout and stats history, and the only measurements it records are body weight and waist. Hevy Pro removes those limits and adds a set count per muscle group, a warm-up calculator and Hevy Trainer (Hevy). Saving one of Hevy's library programs creates a folder with each of its routines (Hevy); Hevy's help center doesn't say whether those count toward the 4.

StrengthLog's listing puts unlimited workouts and unlimited custom exercises in the free version, along with your own routines and programs with linear progression, PRs and exercise history, body measurements and a calendar (App Store). It gives no number of routines for the free version, while its Premium list starts with "Build unlimited training routines and programs with double and triple progression"; whether free routines are capped isn't stated. Premium adds the full program library, double and triple progression, RPE and RiR logging, % of 1RM, advanced statistics and monthly and yearly training reports (App Store, StrengthLog).

The two apps charge for different things. Hevy lets you log RPE for free, from 6 to 10, with no separate RiR option (Hevy); in StrengthLog, RPE and RiR logging is Premium (StrengthLog). StrengthLog's help center says its muscle-map widget, which counts your sets per muscle each week, is for Premium users (StrengthLog), and so is Hevy's set count per muscle group.

In StrengthLog you pick it, with help from your log. When you add an exercise, it can copy the sets from the last time you logged it (StrengthLog). In a program or saved workout, a set can use "Retrieve from log": the app finds the last time you did that number of reps on the exercise and uses that weight, or a heavier one if you've since done more reps with it. If the program says 10 reps and you did 8 last time, it fetches no weight (StrengthLog). Adding a fixed amount, such as 2.5 kg, to the fetched weight each time is Premium (StrengthLog).

In Hevy's free version, a routine's weight and reps update to what you did when you save the workout, unless you turn that off on the save screen or the exercise uses a rep range, and a Previous column shows your last session's numbers (Hevy). Hevy Trainer, which is Pro only, builds a program from your goals and tells you when to increase the weight and by how much (Hevy). What Trainer adds is in the Hevy app review.

In both free versions the app shows what you did and you decide when to add weight. StrengthLog's listing says the free version builds programs with linear progression (App Store), and its help center describes a multi-week program as one week copied forward, with the weights edited each week (StrengthLog). The weight-progression guide covers when to add weight.

StrengthLog's website says its coaches have built a library of over 300 programs and workout routines, for powerlifting, bodybuilding, powerbuilding and general strength and muscle growth (StrengthLog). In the app you filter them by Premium or Free and by level, and the Premium ones need Premium (StrengthLog).

Hevy's library has 26 programs, filtered by level, goal and equipment, plus seven routine categories such as at home, dumbbells only and travel. Hevy's free-versus-Pro table doesn't list the library as Pro, and you can edit any routine you save (Hevy).

If a program library is why you'd pay, StrengthLog lists over 300 programs and routines together, and Hevy 26 programs plus its routine categories. If you want a free program to start from, you can save one from Hevy's library, but Hevy doesn't say how they count toward the 4-routine limit.

A year of Hevy Pro costs $85.01 less than a year of StrengthLog Premium in the US, and 700 kr less in Sweden. In Sweden, Hevy's lifetime purchase costs 995 kr, the same as one year of StrengthLog Premium; in the US it's $74.99 against $109.00 (App Store, App Store). Hevy's listings show two monthly prices and don't say which one you'll be offered (App Store).

A few times a year, Hevy offers 50% off the first year of an annual plan to people who have never had Pro; it renews at the regular price, and lifetime is never discounted (Hevy). Hevy Pro covers one account and isn't part of Family Sharing; a second account's subscription is bought on Hevy's website (Hevy).

In Sweden, you can pay for StrengthLog Premium with a wellness stipend (friskvårdsbidrag) through Benify, Actiway, Wellnet, ePassi or Benefits, or with an invoice for a year at a time. StrengthLog says App Store and Google Play receipts can't be used for the stipend, and that you should cancel an App Store subscription first or you'll be charged twice (StrengthLog). Hevy's help center says nothing about the Swedish stipend; its support team does connect a Wellhub subscription to a Hevy account (Hevy).

Hevy accounts are public by default: people can see your profile and workouts unless you turn on a private profile. Even then, the Discover feed stays on the home screen (Hevy). Version 9.1 of StrengthLog added friends, with a limit of 25 and no public profiles, and its listing says your full training log stays private; friends see summaries of your workouts (App Store).

If you want to follow other lifters and post your workouts, Hevy's public profiles and feed suit that. If you want a log only you and up to 25 friends see, StrengthLog suits that.

If you cancel StrengthLog Premium, your log, programs and workouts stay, but workouts and programs you built with Premium functions can't be started until you pay again (StrengthLog). If you leave Hevy Pro, you keep routines and custom exercises above the free limits but can't create new ones, and your workout history stays on Hevy's servers, so the 1-year and all-time stats come back if you resubscribe (Hevy).

Hevy imports only CSV files exported from the Strong app (Hevy), so it has no direct import of a StrengthLog history.

• Pick StrengthLog if you want to stay free with unlimited custom exercises and no stated routine cap, want a large program library and can pay for it, or want to pay with a Swedish wellness stipend.
• Pick Hevy if you want a public feed, RPE logging for free, a web app or Wear OS, or the cheaper paid plan: $23.99 or 295 kr a year, or a lifetime purchase.
• If you'll pay either way, Hevy Pro adds unlimited routines, full history and Trainer for less; StrengthLog Premium adds its full library, RPE and % of 1RM planning and training reports.

GainsLog is a workout app for iPhone and iPad, with an Apple Watch companion, for lifters who want to build muscle and be told what to lift each session. On the free version it logs unlimited workouts and sets a weight and rep target for each set you've logged on an exercise recently, plus an RIR target in some cases. Up to 3 saved workouts are free. Premium adds the program builder, ready-made programs and custom exercises, at $5.99 a week with a free trial, or $39.99 a year without one, in the US (79 kr or 499 kr in Sweden). A lifetime purchase, $79.99 or 999 kr, unlocks Premium without Gains Coach, its AI coach.

GainsLog lacks some things both apps have. Its Android app is in closed beta, it has no social feed, it can't import a StrengthLog or Hevy history, and its listing counts 100+ exercises, with machines first (App Store). Head-to-heads: GainsLog vs StrengthLog and GainsLog vs Hevy.

If you'd rather have each set's weight and reps set from what you logged, on the free version, see how GainsLog works.
