SweatheartsTrain together. Stay Sweathearts.
One shared strength & nutrition app for you and your partner — lifts, food, water and progress, synced across iPhone and Apple Watch.
Your whole training life, shared
Strength, cardio, nutrition, hydration and body metrics — for both of you, without five different apps.
Strength that remembers
Every session is a full workout of many exercises. Last-time weights are right there, so you always know what to beat.
Watch + phone, one session
Start on your iPhone, log a set on your Apple Watch — both stay in sync. Heart rate, calories and sets, one HealthKit session.
Food without the fuss
Log meals against your daily targets. Protein goals are set for real results — 2g per kilo of your goal weight.
Hydration at a glance
Tap to add water, see exactly how much is left, and set custom vessel sizes for the mug or bottle you actually use.
Progress you can feel
Weight trends, streaks and PRs. Watch the numbers move week over week — and celebrate the wins together.
Two people, one team
See each other's sessions and streaks. Accountability built in — because you're more likely to show up when someone's counting on you.
Every screen, one shared app
Workouts, progress, accountability and nutrition — fanned out like a hand of cards. Hover any screen to bring it forward.
Made for Apple Watch
Leave your phone in your bag. Track your rings, log your sets and watch your heart rate live — all from your wrist.
Three steps to your first session
Set up together
Create your accounts, pick your goals, and choose the look that fits you — Daylight, Patisserie or Forge Dark.
Follow your plan
Open today's session on your phone or watch. Everything you need to lift, eat and hydrate is laid out for you.
Watch it add up
Log as you go. Streaks build, weights climb, and you both see the progress — day after day.
Frequently asked questions
Is Sweathearts really made for two people?
Yes. It's designed from the ground up for a pair — you and your partner — so you can train, eat and stay accountable together rather than tracking alone.
Do I need an Apple Watch?
No, but it's better with one. Your iPhone does everything; the Apple Watch adds live heart rate, calories and set-logging from your wrist during a workout.
Where is my data stored?
Your workouts, nutrition and metrics are tied to your account and synced securely. Nothing is ever sold or shared with advertisers. See our Privacy Policy for the details.
Does it work with Apple Health?
Yes. Sweathearts records your workouts as HealthKit sessions with heart rate and calories, so your training shows up in the Health app alongside everything else.
Can I use it offline?
Absolutely. Sweathearts is offline-first — you can log a full session with no signal, and it syncs quietly once you're back online. Nothing blocks you mid-workout.
How do I delete my account and data?
Any time, from inside the app or from this website. Visit the Delete Account page for step-by-step instructions — your data is removed for good.
