FitMaxx: HIIT Interval Timer

FitMaxx is the HIIT timer that pushes back — a loud, beautiful interval timer with a real coach built in. Pick a plan, hit start, and every interval tells you exactly what to do. Phone in your pocket, you still hear every rep.

No account. No ads. No tracking. Fully offline. You're training in ten seconds.

BUILT FOR INTENSITY
• A full-screen timer that changes color as you move from WORK to REST, with a glowing progress ring so you read it across the room.
• Countdown beeps and haptics you feel without looking at the screen.
• Not just a stopwatch — every interval shows the exact exercise, so you always know the next move.

12 GUIDED PLANS
Tabata Classic, Beginner Burn, 7-Minute Classic, Advanced HIIT, Sprint Intervals, Core Crusher, Fat Burn Express, Upper Body Push, Leg Day, Full Body Blast, Morning Wake-Up and Mobility Flow — from a 4-minute Tabata to a full-body blast.

40+ GUIDED EXERCISES
Every move comes with an animated demo, step-by-step form cues, the common mistake to avoid, the muscles it targets and a difficulty rating. All bodyweight — no equipment, no gym, just this screen.

TRACK EVERY SESSION
• Automatic calorie estimates based on your body weight.
• Save workouts to Apple Health with duration and calories.
• Build a streak and watch your weekly minutes, rounds and calories grow.
• Share a workout card when you crush a session.

YOUR AI COACH
• A daily recommendation that reads your training log and tells you what to train today — and when to take active recovery.
• A weekly recap plus a personal chat that actually knows your history.
• Runs on Apple's on-device intelligence when available, so your coaching stays private. General fitness guidance only — never medical advice.

PRIVACY FIRST
FitMaxx collects nothing. No account, no analytics, no third-party tracking. Your training log lives on your device and only leaves it if you choose to save to Apple Health — that's why our privacy label reads "Data Not Collected".

Stop paying a coach to count to twenty. Download FitMaxx and light it up.
