This isn't a plan you get once and tick off. It's a coach that looks at your body every day, knows your road to race day, and explains every decision — including the hardest one: when to back off even though you feel great. Whether it's your first 50k or you're fighting for the podium — if you run ultra, this is for you. The goal is simple: to get you to the start line fresh and confident — not overtrained, not guessing. It runs fully on heart rate; a power meter is an option, not a requirement. YOUR DAILY RHYTHM • Morning check-in: three numbers before you get out of bed — energy, motivation, soreness (1–10). Ten seconds, and they add context no sensor can catch. • Morning report: when your watch syncs the night — never at a fixed hour — it combines HRV, sleep and A:C ratio with your check-in and tells you exactly what to do today. • Post-workout report: detects the activity automatically and judges whether the session fit your phase. Fast, concrete feedback. EVERY NUMBER MEANS SOMETHING • Form of the Day — HRV trend, sleep, TSB and your morning check-in in one clear signal. • Safety check — A:C ratio, connective-tissue window, injury history, flagged every day. • A precise prescription — heart-rate zone, TRIMP target, duration and terrain. Not "easy run" but: HR 130–140, 40 min, forest trail. • Weather awareness — conditions where you are feed straight into the prescription: pace and electrolyte tweaks, warnings for heat, cold, wind and slick descents. • Phase and goal context — where you are in periodization, days to race, and what this phase demands (like the tissue-recovery window after an ultra). • An antidote to "the watch is lying" — it reads Garmin Training Status / "Unproductive" in the context of your phase: a dip in form and deliberate recovery are not the same thing. GOT A POWER METER? EVEN SHARPER Connect Stryd or another power meter and your prescriptions and race analysis gain watt targets alongside heart-rate zones — power on the climbs, where heart rate lags. Without a meter, everything runs fully on heart rate; you lose nothing from the core app. RACE PLANNER (GIS-grade spatial analysis) Upload your route (GPX) — UltraFlow reads the terrain with a precision most apps don't even touch: elevation, gradients, surface and technicality classification, run/hike segments. You get an execution plan for race day: heart-rate and pace targets segment by segment (power if you have a meter), run/hike calls, a weather strategy and a computed pack weight for each section — trimming excess, never mandatory kit. IT ADAPTS TO YOU Your heart-rate thresholds, how you respond to load, how you pace climbs and descents, your race history — the plan fits how you actually run, not an average. Got a power meter? It adds power zones and CP. The longer you use it, the better it fits. ## Version history (last 5 releases) ### 1.8 — 2026-08-22 • Checked in early?

Upload the CSV in Settings and HRV starts working from day one instead of a month later • The plan explains every session: tap to see what it is for, and tick off a workout up to three days back • First launch walks you through setup instead of leaving you on an empty screen • A week with a race shows it in the header, with its distance and vertical gain • The report opens from the last downloaded version, without waiting for the network • Stability fixes and small improvements ### 1.6 — 2026-08-17 • Pull down to refresh — Today, Training, Plan and History fetch fresh data without restarting the app • A finished race now counts as done — no more “prescribed, not ticked” under a race you actually ran • Vertical gain builds across the whole block and peaks in the specific phase, instead of flat-lining from week five • The post-workout report converts segment pace to vertical-equivalent before calling anything a crisis — a slower stretch in the mountains is no longer read as a collapse • Naps count towards your sleep assessment, tracked separately from night sleep • A race finishing after midnight gets its own report and is no longer overwritten by a shorter activity later that day • Stability fixes and small improvements ### 1.5 — 2026-08-15 • Home Screen and Lock Screen widgets — readiness and race countdown without opening the app • Plan rebuilt: 10-week block axis, day load, connective-tissue conflicts flagged on the session itself • Week ribbon — all seven days at a glance, no scrolling • Clearer trend charts: a line instead of a cloud of dots, metric colours matching the report • Check-ins reset at midnight, and the notification opens the right card • The route planner now works without an account — drop in a GPX for pacing, roadbook and fueling • Stability fixes and small improvements ### 1.4 — 2026-08-10 • Coach's analysis in the Training tab — expandable for every session • Two workouts in one day now get separate cards, each with its own analysis • Stability fixes and small improvements ## Related topics [ultra flow](https://appshunter.io/ios/topics/ultra-flow) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
