Mesolab vs RP Hypertrophy
Two hypertrophy apps for iPhone, compared on what each publishes about itself. Mesolab is the publisher's own app, so this is a labelled comparison, not a neutral review. Sources and dates are 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
Both are built for training toward muscle growth on iPhone. RP Hypertrophy is Renaissance Periodization's app, with 45+ plans and a Meso Builder, and it is also browser-based. Mesolab is an iPhone-only app that plans a block with you and logs weight, reps and RIR against targets. The clearest differences on their own pages are price and how you start: Mesolab's first completed workout is free; RP's web page shows no free trial.
