ProductOne aggregates data from the apps serious lifters already use — Hevy, Cronometer, Garmin, and Withings — into a single intelligent dashboard that reveals the cross-domain correlations hiding in siloed data.

You log sets in one app, food in another, track sleep on your wrist, and weigh in on a smart scale. No platform connects workouts, nutrition, sleep, and body composition — until now.
Launching with these four integrations — with more platforms on the roadmap.
OAuth integration with Hevy, Garmin, and Withings. CSV import for Cronometer. All your data flows into a single intelligent dashboard that reveals what scattered apps never could.
ProductOne adapts its metrics, alerts, and insights to your current training phase. What matters changes depending on your goal.

ProductOne analyses the interplay between your training, nutrition, recovery, and body composition to surface the cross-domain correlations that siloed apps can never see.
Correlation Spotting: Discover how sleep quality, calorie surplus, and training volume interact to drive or stall your progress.
Anomaly Detection: Get alerted when biometrics deviate from baseline before overtraining sets in.
Phase-Aware Coaching: Insights adapt to whether you're bulking, cutting, recomping, or maintaining.
Weekly Digests: A summary of what moved, what stalled, and what to adjust this week.
Your bench press has increased +5kg over 3 weeks, coinciding with improved sleep averaging 7.1h. Correlation confidence: 0.82.
HRV is at 42ms (baseline 58ms). Sleep architecture shows poor REM. Suggest capping today's squat session at RPE 7.
Bodyweight stalled at 84.2kg for 12 days. Calorie average at 2,850 kcal. Suggest a 200 kcal increase to break the plateau.
Seven integrated sections that give you the complete picture — from today's session to your long-term trajectory.
Lift progression charts, volume heatmaps by muscle group, frequency tracking, and personal records — all synced from Hevy.
Calorie and macronutrient tracking with daily and weekly views, macro split breakdowns, and trend lines imported from Cronometer.
Sleep, HRV, stress, body battery, training readiness, and resting heart rate — your dedicated Garmin biometric hub.
Withings body composition plus manual measurements. Track shoulder-to-waist, waist-to-hip, chest-to-waist, and calf-to-arm ratios over time.
A visual timeline alongside your quantitative data. See exactly how you looked at specific body fat percentages and training volumes.
Personalised insights based on your complete physiological profile. Weekly digests, plateau detection, and periodisation advice.
