DimensionScoreEvidence
Plan quality3Vendor describes a machine-learning model on per-second HR response, individualised polarisation and Riegel-based predictions, and critiques the TSB model; no stated periodization model and no independent confirmation. evidence checked 2026-10-13
Adaptation4Trustpilot users confirm the next sessions change based on recent runs; vendor documents whole-plan recalculation after missed runs, illness and fatigue signs in HR data, but states HRV is not used. evidence checked 2026-10-13
Workout feedback3Steps carry pace/HR/power targets and run on Garmin; after each run the app derives a workout-adherence score, run classification and physiological load, but the vendor documents no plan-relative debrief and states per-workout reasons are not shown. evidence checked 2026-10-13
Coaching relationship1No coach chat; the vendor's only channel is an 'ask a question' form answered within 3 business days, for Premium and trial users only. Features page lists no conversation feature. evidence checked 2026-10-13
Transparency3Public FAQ and glossary document model behaviour (Artemis, plan volatility, non-determinism, why HRV is not used); per-session change reasons are not documented. evidence checked 2026-10-13
Value for money4Free tier includes an adaptive 7-day plan; Premium GBP 9.99/month or 99/year. A Trustpilot reviewer: 'Free version works great but if you want a bit more customisation then definitely worth the subscription'. evidence checked 2026-10-13
