Level up your fitness with HIITFlow. HIITFlow transforms high-intensity interval training from a simple countdown into a progression system that rewards consistency. Every rep earns XP. Every session builds your streak. Every week paints your Heat Map. This is HIIT with purpose. WARRIOR XP SYSTEM Earn XP for every exercise you complete and bonus XP for finishing your session. Watch your rank climb through six tiers β€” Rookie, Warrior, Elite, Champion, Legend, and Immortal. Your level badge updates in real time, giving you a clear picture of how far you have come and how close you are to the next rank. DAILY FLAME STREAKS Consistency beats intensity. HIITFlow tracks your daily training streak and rewards you with an animated flame that glows brighter at five days and beyond. Miss a day and the counter resets β€” simple, honest accountability. HEAT MAP DASHBOARD A 12-week heat map visualizes your training frequency at a glance. Tap any cell to see the exact XP earned that day. Spot patterns, identify rest weeks, and stay motivated by watching the grid light up over time. FLEXIBLE TIMER Configure exercises, work duration, and rest duration independently. Support for 1 to 50 exercises per session, with granular control over intervals. The full-screen timer is designed to be readable mid-workout with high-contrast colors and bold typography. APPLE HEALTH INTEGRATION Pro users can save completed HIIT workouts directly to Apple Health. Your sessions count toward Activity rings and appear alongside your other fitness data. HIITFlow requests only the permissions it needs β€” write access for workouts β€” and nothing more. PRIVACY FIRST HIITFlow stores all XP, streaks, and workout history locally on your device using standard system storage. There are no accounts to create, no cloud sync, and no analytics tracking. Your fitness data stays yours. ACCESSIBILITY HIITFlow is built with inclusivity in mind. Full VoiceOver support ensures every button, card, and stat is clearly labeled for screen reader users. Dynamic Type compatibility allows text to scale with your system preferences. All locked and unlocked states use icons alongside color to support users with color vision differences, and every interactive element meets the 44-point minimum touch target for ease of use during intense workouts. ONE-TIME UNLOCK HIITFlow Pro is a single, lifetime purchase β€” no subscriptions, no recurring charges. Free users get the full timer experience. Pro unlocks XP progression, streak tracking, the Heat Map dashboard, and Apple Health integration. A Restore Purchases option is always available. Built by a fitness enthusiast who wanted a HIIT timer that felt like a game. No ads. No data collection. Just train, earn, and level up.
