01
Start at the scariest moment
We prototyped the walk-in first — the three taps from opening the app to a started set. If that moment didn't feel calm and certain, nothing downstream mattered. Everything else was built outward from it.
IRONPARK
EVERYONE STRONGER
A pocket strength coach that turns gym-floor guesswork into a plan.
MOBILE APP
— 01 / OVERVIEW
IRONPARK set out to fix the most common reason people quit the gym: standing on the floor with no idea what to do next. Everyone Stronger is the iOS app that answers it — coach-built sessions, a weight engine that adapts to every lift you log, and step-by-step guidance designed for one sweaty hand between sets.
— 02 / THE BRIEF
Most gym apps hand you a library and ask you to be your own coach.
IRONPARK's research kept surfacing the same person: motivated, paying for a membership, and quietly overwhelmed. Hundreds of exercises, no plan, no idea how much weight to load, and a creeping sense that everyone else in the room had a script they'd never been handed. Most fitness apps made that worse — more choices, more logging, more decisions at the exact moment decision-fatigue is highest.
The brief was deceptively small: get someone from "I walked in" to "first set started" in under three taps, then hold their hand through every rep, set, and swap without ever feeling like a spreadsheet. It had to work for a nervous beginner and a returning lifter — on a phone, one-handed, mid-set, with chalk on the screen.
— 03 / APPROACH
Four moves that
mattered more than the tech.
02
Make the weight trustworthy
A recommendation you don't believe is worse than none. The adaptive engine adjusts each lift from what you logged last time, the coaches' programming rules, and how the last set actually felt — and shows its reasoning.
03
Design for a sweaty hand
Big tap targets, one-handed reach, swipe-to-swap, and a rest timer you can read across the room. Every interaction was tested mid-set, on a real gym floor, not a quiet desk.
04
Earn the subscription
Seven full sessions free, no card, no countdown. IRONPARK+ unlocks only once the app has already proven it can coach you — so the paywall feels like a yes, not a wall.

Full sessions before IRONPARK+ is ever mentioned
IRONPARK is the first build where members told us the app felt like a coach, not a spreadsheet. People who'd quit the gym twice are still logging sessions six months later.
