The short version

  • Only StrongLifts has a free tier, so it costs nothing to try first.
  • Each has a real cost: RP Diet requires users to commit to detailed macro tracking, which is time-consuming for some athletes; StrongLifts it is built around one specific programme, so once a lifter progresses beyond what 5x5 is designed for and stalls, the app's core structure no longer fits their needs and they typically need a different programme entirely.
  • They diverge on capability: RP Diet covers Personalized meal plans, StrongLifts covers 5x5 programme tracking.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

RP Diet

  • Requires users to commit to detailed macro tracking, which is time-consuming for some athletes
  • Limited meal delivery partnerships compared to competitors

StrongLifts

  • It is built around one specific programme, so once a lifter progresses beyond what 5x5 is designed for and stalls, the app's core structure no longer fits their needs and they typically need a different programme entirely.
  • Full functionality requires a paid subscription, and the free tier is limited enough that serious use of the programme effectively requires paying.
  • It offers little flexibility for customising exercises or set schemes compared with general-purpose workout loggers, since flexibility is not the point of the product.
  • 5x5 as a method is not suited to every body or goal, for example it is not designed for hypertrophy-focused or advanced lifters, and the app does not steer users away from it once it stops being appropriate.
  • Subscription billing continues after a user has outgrown the programme unless actively cancelled, which is a common pattern across fitness app subscriptions generally.
