Flintwork

Flintwork is a simple, free interval workout timer for bodyweight training — no gym equipment, no account, no subscription. ROUTINES Start with five ready-made routines (Full Body HIIT, Quick Core, Beginner Cardio, Tabata Classic, Stretch & Cooldown) or build your own from the exercise library, setting custom work and rest times for each move. LIBRARY Twenty bodyweight exercises across warmup, strength, cardio, and cooldown categories, each with a short instruction so you always know what's next. RUN A clear full-screen timer shows the current exercise, round progress, and remaining time, with pause, skip, and stop controls. HISTORY Every completed workout is logged locally, with your current streak and total session count. Flintwork has no account, no server, and no in-app purchases. Everything is stored on your device, and the app is supported by ads.
