Four meaningful upgrades for serious lifters who want more depth.
After every workout, your AI coach reviews your session and gives personalized insights — what went well, what to adjust, and how to improve next time. Only available in Pro.
Deep analytics across your training history — volume trends, muscle group breakdowns, PR progression charts, and more. Understand exactly how your training is evolving.
The free tier supports up to 3 saved workout templates. With Pro, there's no limit — build as many programs, routines, and templates as you want.
See exactly which plates to load on a visual barbell diagram. Free tier shows text only. Pro gives you the full visual layout so there's no guesswork at the rack.
You don't need Pro to have a great experience. Everything below is free, forever, with no ads.
IronStack Pro offers three plans: Monthly at $2.99/mo (auto-renews), Yearly at $19.99/yr (saves 44% vs monthly), or a one-time Lifetime upgrade for $39.99. All plans unlock the same Pro features. The Lifetime plan is the best value — pay once and own Pro forever.
Yes. The Lifetime plan is a single one-time payment of $39.99. No renewals, no recurring charges — ever. Hevy's lifetime is $74.99 and Strong's is $99.99; IronStack's is less than half the price of either.
Nothing bad. The free tier works great — no ads, no paywalled nags during workouts, no degraded experience. You can log unlimited workouts, but you're capped at 3 saved templates, 3 AI generation tries, and a text-based plate calculator. When you're ready to go deeper, Pro is there.
Inside the IronStack app — go to Settings and tap Upgrade to Pro. The purchase is processed through the App Store (iOS) or Google Play (Android), so it's handled securely by Apple or Google.
Yes. Use the "Restore Purchase" option in Settings to restore your Pro access on any new device linked to the same App Store or Google Play account.
