Best hypertrophy apps for iPhone in 2026
Four hypertrophy apps for iPhone, compared on what each one publishes about itself. Mesolab is the publisher's own app, so read this as a labelled comparison, not a neutral ranking: the criteria, the sources and the date are all below.
Disclosure: Mesolab is the publisher's own app, so this page is not neutral and does not pretend to be. Everything about the other apps comes from their own websites and App Store listings, read on 21 October 2026, and is linked beside each fact. Apps change; check the linked page before you decide.
Short answer
All four apps below plan or recommend your training on iPhone; none is the single right pick for everyone. Choose by what you will actually tap: Mesolab (iPhone only) logs weight, reps and RIR against a block it plans with you; RP Hypertrophy is Renaissance Periodization's own app; Alpha Progression has a free tier and a Pro plan; Boostcamp has a free tier with a large program library.
How the apps were picked and compared
Criteria: the app runs on iPhone, it is built for training toward muscle growth (not general fitness), it gives you a plan or recommends weights, and it tracks effort or volume. The four apps are the four apps whose own pages were read for this comparison; this is a short list, not a survey of every app, and it is not a ranking.

Which to try, by what you want
- A plan built from weekly sets, RIR and a deload, plus a record of what you trained: Mesolab. See how a mesocycle is planned and what RIR means. It is iPhone only and needs iOS 26.
- A large catalog of plans and a Meso Builder: RP Hypertrophy lists 45+ plans and a Meso Builder.
- Android as well as iPhone, or a free tier to start: Alpha Progression and Boostcamp both describe a free tier and list Android.
A free tier or trial lets you test the logging flow before paying anywhere. Whichever app you pick, the useful habit is the same: log the weight, the reps and how hard the set was, every session.
