About Octane Fuel:Training with Data
Octane reads your plan, your recovery, what you ate, the weather and the protocols you're on, and gives you one recommendation each morning: proceed, ease off, shorten, or recover. Then it reads the session you actually did against your own history, and the morning after tells you how your body responded. WHAT IT READS • Your plan, from Runna's private calendar link. What's planned today, what's next, which session is key. • Recovery from Oura, Garmin or Apple Health: sleep, resting heart rate, HRV and training load, against your own 28-day baseline. • Fuel: what you ate yesterday and today, against the day's target. • Conditions: heat and humidity, as a range to plan by. • Protocols: what you take, when, and how you've felt since. THE RECOMMENDATION Every morning, one line, with the why behind it. On an easy day before a key long run, with HRV 18% below your baseline, Octane says to cut the volume and protect tomorrow. The advice only ever recommends less. YOUR RUN, READ Every run is read against your own past runs of the same distance and type. Tempo miles listed as they happened. Heart-rate recovery against your usual. In words, not scores. THE MORNING AFTER Whether your body responded in its usual range, or not, in plain words. NUTRITION Log by photo, voice, barcode or search. Every estimate is editable, and the edited value is what gets logged. Ten meal slots including pre-run, during and post-run. Water against a target. A target for each kind of training day, because a long-run day and a rest day are not the same day. PROTOCOLS Supplements, medications and GLP-1s, recorded as stated. Doses, how you're feeling, and adherence kept honestly. Octane records doses and never computes one. WHAT OCTANE DOESN'T DO It learns patterns. It doesn't invent causes. Below the trust floor it says nothing. A missing day is absent, never zero. FREE AND PRO Free is the app itself: connections, logging, the recommendation's verdict. Octane Pro adds the why behind every recommendation, the session read, the morning-after response, the written morning brief, and meal plans. 14-day free trial, then $14.99 a month or $99.99 a year. Cancel any time in Settings. Octane is not medical advice. Terms of Use: https://octanefuel.app/legal/terms Privacy Policy: https://octanefuel.app/legal/privacy
