Three tasks a day. Less noise. More progress. Trio Focus strips productivity down to three things. Not endless lists that guilt you into overplanning. Just the tasks that count today - focused on, one at a time. Designed for people who want to finish the day feeling accomplished, not overwhelmed. WHY THREE? Research on deep work suggests most people can only sustain 3โ€“5 hours of focused effort per day. Trio Focus honours that limit by design โ€” so you pick less, finish more, and stop pretending you'll do it all. HOW IT WORKS - Add up to three tasks for the day - Tap Focus to start the timer โ€” 10, 25, 45, or 60 minutes - Finish one before moving to the next - Check them off as you complete them - That's it FEATURES - Beautiful, calm iOS-native design - Focus timer with customisable durations - Swipe through days to see your history - iCloud sync across your iPhone and iPad - Share tasks with friends via iMessage - Organise by Mode โ€” Work, Personal, Study, Health, Finance, Side Project - Works offline, respects your privacy TRIO PRO Unlock everything with a one-time purchase. No subscription, no recurring charges โ€” pay once, keep it forever. - Modes โ€” organise tasks by area of life - iCloud backup & sync - Custom timer presets - Task sharing via iMessage Start with a 7-day free trial of Pro. Continue with the basics after โ€” no payment required. WHO IT'S FOR - People who plan too much and finish too little - Anyone feeling overwhelmed by their to-do list - Students, professionals, creatives, parents โ€” anyone who wants calm focus - People with too many tabs open, mentally or otherwise PRIVACY Your data stays on your device and in your private iCloud.

TOO MUCH TO DO? START WITH THREE. When everything feels urgent, a giant to-do list just makes it worse. Do3 quiets the noise by showing you only three tasks at a time. Finish your three, then choose: do three more, or call it a good day. That's the whole idea. Small rounds instead of one endless list. Momentum instead of overwhelm. HOW IT WORKS Do3 reveals one task at a time, so you're never staring at everything at once. Do it and tick it off, or skip it if now isn't the moment. You get a daily skip allowance, so you can nudge past the odd task without dodging your whole day. Clear your three and you get a quick well done, then it's your call: another round, or stop for the day. You're finished when you decide you are. FOR BUSY BRAINS If you have ADHD, a head full of open tabs, or simply too much on, Do3 is built for you. No guilt-trip lists, no wall of red. Just the next three things, one at a time, so starting feels possible again. BRING YOUR TASKS WITH YOU Already using something else? Switching is easy: โ€ข Import from other to-do apps with a CSV file โ€ข Import straight from Apple Reminders, it copies them across and leaves Reminders untouched โ€ข Export any time, free, as a CSV or a full backup, so your tasks are never locked in EVERYTHING ELSE YOU NEED โ€ข Quick add that understands you: type "pay rent tomorrow 2pm high priority" and Do3 fills in the date, time and priority โ€ข Brain Dump to empty your head fast, then sort later โ€ข Focus tags like Quick wins, Deep work and Low energy, to match tasks to the energy you have โ€ข Time blocks and a Calendar to shape your day without rigid scheduling โ€ข Repeating tasks with real control: daily, weekly, monthly, "the last Friday", or repeat until done โ€ข An All Tasks view with search, filters and sorting whenever you want the bigger picture โ€ข Apple Watch app and Home Screen widgets that show your current round โ€ข A Deleted list and an Undo, so nothing vanishes by accident WORKS EVERYWHERE, PRIVATELY Do3 syncs across your iPhone, iPad and Mac through your own iCloud, automatically. No account to create, no password to remember. There's no server, no tracking and no analytics, so your tasks stay yours. Nobody, including us, can see your list. SIMPLE PRICING Use Do3 free for your first 7 days. After that, a one-time purchase unlocks it for good, with no subscription, ever. One purchase covers your iPhone, iPad and Mac. And exporting your tasks is always free, so you are never locked in. Start with three. See how much lighter that feels.
