Hammy: Indoor Cycling

Smart Trainer ERG Workouts

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Smart, structured indoor training for the winter months. Follow a plan built around your FTP and start spring faster than ever. Try 7 days free. Get faster every time you clip in. Hammy turns your smart trainer into a coach that always has the next workout ready. Open the app, see today's ride, and be on your first interval a few taps later. Hammy sets the resistance, counts down every block and keeps your week on track, so all that's left for you is the pedalling. ERG THAT WORKS WITH YOU Hammy holds your target watts through every interval, whatever your cadence. Stop to grab a bottle and ERG eases off instead of locking up the flywheel. Start pedalling again and the target ramps back in on its own. The numbers are big enough to read through sweat from the saddle. ALWAYS THE RIGHT WORKOUT Choose from curated sessions for threshold, sweet spot, VO2 and endurance, or build your own in seconds by dragging blocks on a chart. Every target scales with your FTP, so your workouts keep up as you get stronger. New to power training? The Ramp Test finds your FTP in one ride. A PLAN THAT FITS YOUR LIFE Put rides on the days you can actually train. One look at the week shows what's done, what's next and how much load you've built. PROOF YOU'RE GETTING FASTER After every ride you get normalised power, IF, TSS, time in zone and your power charted against the target. Week by week, History shows your training load climbing and your FTP moving up. YOUR RIDES, WHERE YOU WANT THEM Connect Strava and Apple Health once. After that, every ride you finish shows up in both without you lifting a finger. TRAIN TOGETHER WITH DUO One subscription covers two riders, each with their own rides, workouts, plan and FTP. Share it with your partner, a friend or anyone in the family who rides. WORKS WITH YOUR TRAINER Hammy works with any Bluetooth smart trainer that supports FTMS and ERG mode, plus heart-rate straps and cadence sensors. It checks your trainer when you pair it, so you know it's ready before your first ride. After the first sign-in you can ride offline, and your history follows you to a new phone. BUILT FOR IPHONE AND IPAD Hammy is a native Apple app, fast and calm with nothing in your way. On iPad you get today's ride next to your week, and a workout editor the size of your screen. HAMMY PRO Try everything free for 7 days, then choose Solo for one rider or Duo for two, billed monthly or yearly. Payment is charged to your Apple ID when you confirm the purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. You can manage or cancel your subscription in your App Store account settings.
