Your Workouts, Visualized

HIIT Addict is an all-purpose workout timer, fitness app, and interval timer. Most gym timers are just glorified stopwatches. HIIT Addict is much, much more.

Who is HIIT Addict for?

For fitness veterans who need complex intervals and advanced options to create literally any workout structure imaginable.

• Total Control: Chain together interval blocks, warmups, cooldowns, EMOMs, custom blocks, and exercise circuits. Build the exact fitness timer you need.

2. The Minimalist (Basic Interval Timer)
For those who just want a simple, bare-bones work/rest interval timer without the extras.
• Basic Editor Mode: Hides the advanced options so creating a basic interval session stays easy.
• Ready to scale: Switch to "Advanced" mode whenever you want more complex interval structures and options.

3. The Indoor Cyclist (with Smart Trainer Control)
For riders looking for clean, structured cycling workouts on a smart bike or smart trainer, and a free or inexpensive alternative to Zwift, TrainerRoad, and TrainingPeaks.

6. The At-a-Glance User
For people who like to see their entire workout at a single glance. Our workout profile is a feature you won't find in other interval workout apps.
• Height & Color = Intensity: Taller blocks and warmer colors mean higher effort.

With it, you can pace every effort and never get lost in the workout.

Heart Rate Monitoring (HR strap or watch required)
Track performance with real-time biometric stats
