StrengthLog vs Hevy

Pick StrengthLog if you'll stay free (unlimited workouts and custom exercises, free routines and programs with linear progression, against Hevy's 4 routines and 7 custom exercises), and Hevy if you'll pay ($23.99/year or $74.99 once in the US, against $109.00/year for StrengthLog Premium). If you train by reps in reserve, RIRLift beats both: it logs RIR free, which StrengthLog keeps for Premium and Hevy doesn't log, and sets your next weight from it on iPhone and Apple Watch.

StrengthLog and Hevy, on the things that decide it

StrengthLog, Hevy or RIRLift, in two real situations

A coach's spreadsheet written in reps in reserve

An intermediate lifter handed a hypertrophy block where every set reads like "3 × 10, 2 RIR". Free is the budget, and they want the log to understand the target.

AppWhat it does hereFor this lifter
StrengthLog freeLogs the sets and runs linear progression, but RIR logging and double progression are Premium, at $109.00 a year.Works as a log; the RIR column waits for Premium.
Hevy freeLogs RPE, so 2 RIR goes in as RPE 8. You decide each next weight.Fine if you convert by hand.
RIRLiftLogs reps in reserve free and sets the next weight from it, on iPhone or Apple Watch.Fits exactly. iPhone only.

Only one of the three reads "2 RIR" as written without a subscription.

Pull day, curl stuck for three sessions

Chest-supported row for 8–10 and machine preacher curl for 8–12, both at 2 reps left. The curl has sat at 60 lb for three sessions without a new rep, which a log would just keep recording.

ExerciseYou loggedNext sessionWhy
Chest-Supported Row90 lb, 10 / 10 / 9 reps, 2 left90 lb × 10Not every set reached 10, so it holds; the weakest set hit its target of 9, so it aims for 10.
Machine Preacher Curl60 lb × 10 / 9 / 9, third session with no new repOffered: 50 lb × 8Three sessions without a new rep, so the recap suggests a step back about 10% lighter: 60 × 0.9 = 54 lb, rounded down to the stack's 50 lb, rep target back to 8.

You choose Deload or Not yet on the recap. In StrengthLog or Hevy you'd have to notice the stall yourself.

Questions

Is StrengthLog better than Hevy?

On free, yes: unlimited custom exercises and free programs, where Hevy caps routines and custom exercises. Paid, Hevy is far cheaper and adds a web app.

Is StrengthLog really free?

The core is: unlimited workouts, custom exercises, routines with linear progression, a rest timer and plate calculator. Premium adds RPE and RIR logging, double progression, the full program library and advanced stats.

Is Hevy Pro worth it?

At $23.99 a year or $74.99 once in the US, yes, if you need more than 4 routines or 7 custom exercises, or want Hevy Trainer to suggest weights.

Which app logs reps in reserve for free?

RIRLift. StrengthLog keeps RIR for Premium, and Hevy logs RPE.
