Support & FAQ →02 · Everything in one app
One history. The whole picture.
Most workout apps make you choose between strength and mobility. Build treats them as equals. Because that's how you actually train.
Strength, mobility, core, and cardio in one app
Log your lifts on Monday, your FRC session on Tuesday, a core circuit and some zone 2 cardio later in the week. It all lands in one history with no gaps and no switching between apps.
3,000+ guided exercises
From barbell compounds to yoga flows to kettlebell core work, each one comes with form cues, difficulty levels, and common mistakes. Filter by any of nine equipment types, and see your previous performance on every exercise, every session.
Programs built on real science
Tap Create for Me and Build generates a full program from your goal, split, training days, and the equipment you actually have. Volume, rep ranges, and rest all follow current research. Or pick PPL, Upper and Lower, or Full Body. A weekly calendar lays out each day. Show up and execute.
Supersets and smart rest timers
Group exercises into A, B and C supersets, then add, reorder, or split them during a workout. Rest timers run in the background and tell you when it's time. Your phone can sleep while you keep moving.
A recovery score every morning
Build reads your sleep from last night and your recent activity in Apple Health, then gives you a morning readiness score. Now you know how hard to push before you even walk into the gym.
Streaks built for real life
Your streak counts any kind of training, not just lifting. Rest days stay protected. Freezes and pauses keep a streak you worked for alive when life gets in the way.
Badges and trophies
Earn achievements as you train. Chase weekly badges and monthly trophies in bronze, silver, gold, and platinum. Watch them all collect in your own trophy case.
Analytics that mean something
Track volume trends, personal records, weight, and FFMI for body composition. Pull in steps, sleep, and heart rate from Apple Health. The numbers from today show as they happen without dragging your trends down.
The details that earn their keep
A plate calculator helps you load the bar. Logging past workouts covers the session you forgot to start. And a recently deleted view means nothing is ever gone for good.
03 · Why Build exists
I used to work out pretty consistently. Then the pandemic hit, and like a lot of people, I stopped. When I finally got back to it, I realized how much ground I had lost.
I was 40, kneeling down to pick something up off the floor hurt, and getting back up was worse. I wasn't in the shape I thought I was. I needed to actually fix that. Not just look better, but move better.
That meant strength work, yes. But also mobility. FRC for my joints. Core stability so my back would stop aching. Zone 2 cardio because I wanted to be around for my kids' graduations. Real training for real life.
The problem with every other app
I tried a lot of apps. Apple Fitness+, MyFitnessPal, Strong, Hevy, Built with Science+. Each one solved part of the problem. The lifting days were covered.
But when I wanted to log a whole body mobility session, they either didn't support it or made me feel like it didn't count. I'd end up with my strength work in one app and everything else in Apple Notes. There was no single place where the whole picture lived.
So I made what I actually needed
Build tracks everything because that's how I train. Monday and Friday are upper body. Wednesday and Saturday are lower. Tuesday, Thursday, and Sunday are cardio, mobility, and core. It's all training. It all matters. And now it all lives in one place.
I'm not trying to compete with apps that have 200 features and AI coaches and social feeds. Build does one thing well. It tracks your training the way you actually do it. Strength and mobility and core and cardio. The whole picture. Because fitness isn't just about the days you lift heavy.
