When should I pick TriDot?

Pick TriDot if triathlon is your sole focus and you want a triathlon-specific optimization engine with race-time prediction (RaceX) tuning your swim, bike and run together.

When should I pick IntervalCoach over TriDot?

Pick IntervalCoach if you want recovery-aware daily adaptation from 60+ signals, coverage beyond triathlon (including single-sport cyclists and runners plus strength), native Intervals.icu integration, or a lower starting price of €3 a month.

Which is cheaper, TriDot or IntervalCoach?

IntervalCoach starts at €3 per month and tops out around €8. TriDot ranges from roughly $14.99 to $99 a month self-coached (and up to $249 with a coach), so IntervalCoach is considerably cheaper.

When to pick TriDot

TriDot is triathlon to its core. Its optimization engine tunes swim, bike and run training to your data and environment, and the RaceX predictor gives you a projected race time you can plan around. If you’re a triathlete who wants a system designed for exactly that discipline, with race prediction baked in, TriDot is purpose-built for you.

It’s the right pick if your season is organised entirely around triathlon races and you want a tool whose whole worldview is the three-sport athlete, including the way it balances training stress across the disciplines.

When to pick IntervalCoach

Pick IntervalCoach if you want recovery-aware adaptation before each session rather than periodic re-optimization. We read 60+ signals every morning (HRV, sleep, resting heart rate, RPE, load) and confirm, ease or replace today’s workout based on how you actually recovered, then write it to your calendar.

We also cover more than triathlon, cycling, running, trail, swim and strength under one plan, including standalone single-sport athletes, integrate natively with Intervals.icu, ship in 13 languages, and start at €3 a month. If triathlon with race prediction is the whole job, TriDot. If you want a recovery-led coach across any mix of sports, IntervalCoach.

iOS depth, not just iOS presence

Both ship iOS apps, but they focus differently: TriDot on triathlon optimization, IntervalCoach on recovery-aware daily adaptation across sports. On Apple platforms IntervalCoach goes deep. Apple Health is a first-class recovery data source, HRV, sleep, resting heart rate, VO₂ max, heart rate recovery, wrist temperature, blood oxygen, body composition and menstrual cycle data flow automatically into your daily readiness signal, no third-party scripts required. App Intents and Siri shortcuts let you ask "Check my readiness" or "What’s my workout today?". Home and lock screen widgets, Apple Watch complications for training score and today’s workout, and iPad support keep the next session one glance away. Push notifications cover the daily briefing and post-workout analysis, and the entire app is natively localised in all 13 languages, including Chinese, Polish and Czech. If you live in the Apple ecosystem and want your training app to use what Apple already knows about you, IntervalCoach is the more native experience.
