ERG control
Your trainer does the pacing
Start a workout and YourIntervals sends every target to your smart trainer. Pedal faster or slower — your watts stay on target. Big, instrument-style numbers show power, target, cadence and heart rate at a glance.
- Live power, cadence and heart rate with a 3-second power average
- Current interval, time remaining and what’s next
- Intensity control from 50 to 150 %, skip and pause
- Every command is confirmed by the trainer — ERG is never faked
Workout library
62 workouts for every goal
From a 20-minute recovery spin to a three-hour endurance ride: Recovery, Endurance, Tempo, Sweet Spot, Threshold, VO2max, Anaerobic, Sprint and two FTP tests. Every workout is defined as a percentage of your FTP, so it fits you from day one.
- Search and filter by type, duration, difficulty and access
- Colour-coded power profiles you can read at a glance
- Estimated TSS, Normalized Power and intensity factor
- Favourites and quick start

FAQ
Questions, answered
Which smart trainers work with YourIntervals?
YourIntervals works with smart trainers that support the standard Bluetooth Fitness Machine Service (FTMS) with ERG (target power) control. That includes most current trainers from Wahoo (e.g. KICKR CORE, KICKR), Elite, Saris, JetBlack, Zwift Hub, Wattbike and Thinkrider, and Tacx trainers with FTMS-enabled firmware. Bluetooth heart-rate straps and watches in broadcast mode are supported too.
Do I need a subscription or an account?
No. Ten complete workouts — one or more from every training type plus an FTP test — and the full Training Guide are free forever. YourIntervals Pro is a single one-time purchase that unlocks everything. There is no account and no sign-up.
Does it work without internet?
Yes. Workouts, the Training Guide, your ride history and the trainer connection all work fully offline. Internet is only needed for optional Strava uploads and the App Store.
Can I keep my screen locked or watch videos while I ride?
Yes. Intervals keep advancing with the screen locked or while another app is in the foreground, and optional audio cues announce each interval. Keeping the app in the foreground on a stand is still the most reliable setup.
Can I import my existing workouts?
With Pro you can import Zwift workout files (.zwo) and build your own workouts with repeat blocks in the editor. Every ride can be exported as a standard FIT file for Garmin Connect, TrainingPeaks, intervals.icu and others.
Does YourIntervals upload to Strava?
Yes, for free. Connect Strava once in Settings and rides upload automatically after you save them, or tap “Upload to Strava” on any ride.
