Not a static plan that no longer fits two weeks later, but a coach that adjusts as you go. ADAPTIVE PLAN The app tracks how many sessions you complete and suggests adjustments when it makes sense. Missed two workouts in a row? Shift your plan by a week with one tap. Three strong weeks? Consider more volume. Change your weekday availability? Workouts move automatically with you. BUILT FOR YOUR SPORT Specific plans for running (5K to ultra), triathlon (Sprint, Kwart, Olympic, 70.3, Full Ironman), Hyrox, and cycling. Plans use proven periodization with build weeks, recovery weeks, and a focused taper into your event day. FITS YOUR WEEK Set per day how long you can train (1h, 1.5h, 2h, or 3h+). Key sessions like long runs and intervals land on your longer days. Lighter workouts on shorter days. Tell Phasr which days you can do which sport, and the plan respects it. SYNCS WITH YOUR TOOLS Automatic Apple Health integration: completed workouts link to your plan, HRV and resting heart rate are tracked, VO2max informs your pace zones. Push your weekly workouts to your Garmin watch with one tap. Push reminders for upcoming sessions and plan suggestions, respecting quiet hours. TRACKS YOUR TRAINING LOAD Training load metrics (ATL, CTL, TSB) with 14-day charts show how your body is responding. Pace zones are calculated from your threshold pace or VO2max, with safeguards so easy-paced tempo runs do not skew future targets. PRIVATE BY DESIGN All training data is stored locally and syncs only between your own devices via iCloud, so your plan stays in sync across iPhone and iPad. No analytics, no tracking, no third-party data sharing. The developer does not collect any data from this app. Built by athletes, for athletes. ## Phasr Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/7d/f3/cf/7df3cff9-c532-81e9-977d-17e2598d72cf/01-hero.png/1284x2778.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/b4/be/b8/b4beb8e4-6384-6990-8d09-8b11830f34e7/02-suggestions.png/1284x2778.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/01/ab/bb/01abbb81-225e-e9f7-6dac-b7169946f7d6/03-reschedule.png/1284x2778.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/8a/1d/87/8a1d874c-3bc3-fc7f-694e-8b0ae9bf5924/04-time.png/1284x2778.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/65/8b/31/658b3182-7d86-35d0-bc0d-4731de5b079f/05-pace.png/1284x2778.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/6c/3d/5a/6c3d5a99-fe09-756b-433f-86a031dfea93/Simulator_Screenshot_-_iPhone_17_Pro_-_2026-04-16_at_20_59_05.png/1284x2778.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/3e/5b/15/3e5b159e-0c25-617f-fbbd-ba317ecb86af/Simulator_Screenshot_-_iPhone_17_Pro_-_2026-04-16_at_20_59_17.png/1284x2778.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/0c/02/4b/0c024bd7-f29e-40eb-fdde-e8c115dceed4/Simulator_Screenshot_-_iPhone_17_Pro_-_2026-04-16_at_21_02_19.png/1284x2778.png) ## Apps Similar to Phasr - [YMCA of Huntington WV](https://apptail.io/app/ymca-of-huntington-wv-pSVc/south-korea) - [Genetrainer Elite](https://apptail.io/app/genetrainer-elite-SOXg/south-korea) - [TrueRep VBT](https://apptail.io/app/truerep-vbt-kIun/south-korea) - [Eat - Calorie Counter & Diet](https://apptail.io/app/eat-calorie-counter-diet-Fpqp/south-korea) - [AI Endurance](https://apptail.io/app/ai-endurance-EhXt/south-korea) - [Hyrox Workouts - Fitness Race](https://apptail.io/app/hyrox-workouts-fitness-race-kdvv/south-korea) - [Transition: Triathlon Training](https://apptail.io/app/transition-triathlon-training-VWPv/south-korea) - [FITA: AI Gym Coach & Body Scan](https://apptail.io/app/fita-ai-gym-coach-body-scan-NuZw/south-korea) - [Vitenso Health Center](https://apptail.io/app/vitenso-health-center-MCBx/south-korea) - [Evox: WOD Timer & Coach IA](https://apptail.io/app/evox-wod-timer-coach-ia-DAsy/south-korea) ## Phasr Available In - [Australia](https://apptail.io/app/phasr-endurance-coach-lNzz/australia) - [Brazil](https://apptail.io/app/phasr-endurance-coach-lNzz/brazil) - [Canada](https://apptail.io/app/phasr-endurance-coach-lNzz/canada) - [Switzerland](https://apptail.io/app/phasr-endurance-coach-lNzz/switzerland) - [South Korea](https://apptail.io/app/phasr-endurance-coach-lNzz/south-korea) - [Mexico](https://apptail.io/app/phasr-endurance-coach-lNzz/mexico) - [Norway](https://apptail.io/app/phasr-endurance-coach-lNzz/norway) - [United States](https://apptail.io/app/phasr-endurance-coach-lNzz/united-states) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
