THE FOCUS TIMER THAT ACTUALLY GETS THINGS DONE Most to-do apps are great at collecting tasks and terrible at finishing them. tuggle flips that. Add what's on your plate, put one task in front of you, and start the timer. No endless list to scroll, just the next thing and the clock. HOW IT WORKS • Add a task in seconds. Type it, or just talk and let voice capture it • Tap play to start a focus timer (think Pomodoro, without the rigid rules) • Tap the check when you're done and watch it celebrate • Earn XP, level up, and build a daily streak for every task you finish PLAN YOUR DAY WITH AI Tell tuggle what you want to get done in plain language, like "write the report 45m, reply to emails, gym 30m," and it drafts a timed, tagged plan you can start in one tap. BEAT DISTRACTIONS, DON'T JUST TRACK THEM tuggle shows you exactly where your time leaks: how much time you got distracted while you should've been focused. See the pull of every distraction and break the habit. STAY IN FLOW • Live Activity keeps your timer on the Lock Screen and Dynamic Island • Gentle notifications nudge you back when focus slips • Today and Later boards keep the future out of your face until you're ready for it • Tag tasks (#work, #deep, #urgent) and see where your hours really go SEE YOUR PROGRESS Insights turn finished tasks into momentum: focused time, streaks, levels, and ranks that make showing up every day feel good. WHO IT'S FOR If long to-do lists make you freeze, if you have ADHD, work in deep-work blocks, or just want a simpler way to focus on one thing at a time, tuggle is built for the way you actually work. Add it. Time it. Finish it. Then do it again.
