Strong has a basic Watch app. Hevy has no Widget. Fitbod doesn't use Live Activity.
GRVT uses all of it. A serious workout app built by an indie lifter for people who chose
Apple for a reason.
Made by one lifter in Hong Kong · Free to start · $99 lifetime option
I've trained seriously for five years. I've used Strong, Hevy, Fitbod, Jefit. Every one of them is great in some way, and every one of them ignores half of what iOS can do.
You buy an Apple Watch. You expect your fitness app to respect it — not a stripped-down mirror of the iPhone screen.
You pay for Dynamic Island. You expect your rest timer to live there, glanceable, without tapping anything.
You care about HealthKit. You expect two-way sync, real data, not a checkbox during onboarding.
Most fitness apps are built for Android-and-iOS-at-once, which means they can't use any iOS feature that Android doesn't have. GRVT is iOS-only, on purpose, so it can use all of them.
This is the fitness app I wanted to exist. So I built it.
Everything else is table stakes.
Start a workout on iPhone. Log sets on Apple Watch without your phone. Glance at the rest timer in Dynamic Island. Home Screen widget shows today's plan. Live Activity keeps your workout pinned on the Lock Screen. HealthKit reads and writes in both directions. Every Apple surface does its job.
Subscription fatigue is real. You already pay for Netflix, iCloud, ChatGPT, Spotify, Adobe.
You don't need your workout app to join the pile.
GRVT Lifetime is $99.90 one time. Every feature unlocked, every future update included.
Buy it and forget about it. Still prefer monthly? That's $4.99/mo. Free tier forever if you
just want to try.
GRVT is built by Raymond — an iOS developer and serious lifter in Hong Kong.
Not a VC-funded startup optimizing for retention metrics.
Not a corporate team with a distant roadmap.
