ByteRhythm

Your coding sessions deserve better than burned-out eyes and cold coffee. ByteRhythm is the developer companion that keeps you productive, healthy, and in flow. Built by developers, for developers — ByteRhythm combines session tracking, health monitoring, and smart reminders into one elegant app that lives on your iPhone and Apple Watch. CODING SESSION TIMER Start a session with one tap. Track your deep work, review your history, and see exactly where your hours go. Add mood tags and coding notes after each session to capture context you'd otherwise forget. DAILY & WEEKLY GOALS Set custom coding goals and watch your progress fill up in real time. Stay on track with visual progress bars that make consistency feel rewarding. SMART BREAK REMINDERS Configurable reminders for sedentary breaks and eye strain relief. ByteRhythm nudges you at the right moments so you can code longer without burning out. CAFFEINE TRACKER Log your coffee, tea, or energy drinks. ByteRhythm models caffeine half-life decay and predicts when it's safe to sleep — so you can fuel your late-night sessions without wrecking tomorrow. HEALTH INTEGRATION Connect to Apple Health for heart rate, HRV, and sleep data. See how your body responds to long coding sessions and learn your personal patterns. ENERGY DASHBOARD Beautiful charts that map your energy curve throughout the day. Discover your peak coding hours and schedule deep work when you're sharpest.
