Hevy is a solid app — but these are the areas where IronStack goes further.
IronStack gives you personalized AI coaching insights after each completed session. Hevy's AI (HevyGPT) only generates new workouts — it doesn't coach you on sessions you've already done.
Set one timer between sets and a different timer between exercises. Hevy uses a single rest timer. A small detail that makes a big difference for structured programs.
IronStack Pro is a one-time $14.99 Lifetime purchase, compared with Hevy's $74.99 lifetime plan. Pay once with no subscriptions or recurring charges.
IronStack doesn't require an account. Download and start logging immediately. Hevy requires you to create an account before you can use the app.
IronStack is fully localized in English and Spanish. Hevy is only available in English.
IronStack works completely without internet — no account, no setup, no sync required. Hevy is cloud-first: you need an account and internet connection before you can start, and some features require connectivity to function.
Create as many custom exercises as you want, free. Hevy caps you at 7 custom exercises on the free tier — you have to upgrade to Pro to add more.
Hevy is a capable app with AI workout generation, Apple Watch support, and no ads. If you're happy with Hevy, that's fair. But if you want post-workout AI coaching that analyzes sessions you've already completed, two separate rest timers, no account requirement, or a lower one-time price, IronStack is the stronger choice: Lifetime Pro is $14.99 versus Hevy's $74.99.
Yes. Both apps cover the core logging experience well — workout notes, Apple Watch, plate calculator, PR tracking, folder organization, and offline support. The key differences: IronStack adds post-workout AI coaching (Hevy's AI only generates new workouts, it doesn't coach on completed sessions), includes quick +/- taps for faster set logging (weight, reps, and seconds), offers two distinct rest timers instead of one, requires no account to start, and offers Pro as a $14.99 one-time Lifetime purchase with no recurring charges.
Both apps are free to start. IronStack Pro is a one-time $14.99 Lifetime purchase with no subscriptions or recurring charges, compared with Hevy's $74.99 lifetime plan.
No. IronStack doesn't require you to sign up or create an account to start logging workouts. Just download and go.
Yes. IronStack is built offline-first — no account or internet connection required at any point. Hevy can log sets offline once set up, but it requires an account and internet to get started, and is cloud-first by design, meaning your data lives on their servers.
Yes. IronStack includes a native Apple Watch app for logging sets, reps, and weight directly from your wrist. Hevy does not currently offer an Apple Watch companion app.
IronStack supports adding your exercises and workout templates manually. If you have a large history in Hevy, you can rebuild templates in IronStack and start fresh with all the new features going forward.
