A coach in your ear, and a trainer that does the maths. Cadexa controls your smart trainer in ERG mode, watches your heart rate and talks only when it matters. Structured indoor workouts, real routes replayed as gradient, and easy days on foot. Everything runs on your phone, works offline, and there is no subscription. WORKOUTS THAT SCALE TO YOU • 4 × 4 VO2max, 30/15s, threshold, sweet spot, endurance and recovery. Every target comes from your FTP and your effort setting, so the same session works at 70 % on a tired day. • Just ride: pick your watts, no structure, end when you like. • A running 4 × 4 and an easy run, coached by heart rate. • Easy walk, hill walk, recovery stroll and an open-ended mountain hike, with distance, pace and climbing from your phone's GPS. The screen locks itself, so nothing is tapped by accident in your pocket. A COACH, NOT A CHEERLEADER • Spoken cues at the moments that matter: the next interval, one minute left, a heart rate that is still climbing, a cadence that is dropping. Calm or energetic, your choice. • Power is the primary target for intervals; heart rate is context. Cadexa waits for your heart rate to respond before it says anything about it. • A training partner that reads your history and suggests today's session with a reason you can disagree with. REAL ROUTES INDOORS • Import a GPX or TCX from Strava, Komoot or RideWithGPS and the trainer replays the hills. • The next kilometre of road on screen, colour-coded by gradient. The coach calls climbs by time, warns before steep kicks and tells you when to shift down. • Climbs are called by name: “two kilometres at 12 percent, up to Ulriken”, and then “that's Ulriken, over the top”. • Ride against your own best time on a route, and send a route to a friend as a GPX file. HEART RATE, DONE PROPERLY • Estimated max, observed peak and your own alert threshold are kept apart. Cadexa never invents a limit for you. • On medication that lowers your heart rate? Tell Cadexa. Zones then follow the heart rate you actually reach, not an age formula. • Heart Mode for riders training under medical advice: a quick check-in before each session, an “I don't feel right” control that eases the trainer off at once, calmer cues, and a plain-text report you can share with your clinician. AFTERWARDS • Sync to Strava with a map for outdoor sessions. • A share card with a map of where you went, your own photo behind it, and the numbers that matter. • A fitness estimate that updates from your rides, no test required. Or run the max heart rate test when you want one. WORKS WITH Any smart trainer that supports the FTMS Bluetooth standard (Wahoo KICKR, Tacx, Elite, Saris, Zwift Hub and more) and any Bluetooth heart-rate sensor. A simulator lets you try everything without hardware. Cadexa is a training app, not a medical device. It does not diagnose or treat any condition. Follow the guidance you have been given by your doctor, and stop if you feel unwell.
