You open your phone to knock out one task. Forty minutes later you're still scrolling, the task is still undone, and your to-do list just got longer. Sound familiar? just Focus is the habit-building companion for anyone who struggles to start deep work, stay off their phone, and keep momentum going day after day. No lectures, no guilt trips - just a simple loop that actually sticks: Plan, Focus, Reflect, Grow. WHY IT WORKS Most focus timers ignore how you feel. Most habit trackers ignore whether you actually got work done. just Focus connects both, so every session moves your real goals forward - and your companion notices when you show up. ONE-TAP DEEP WORK Stop negotiating with yourself before every task. Pick a duration - 25, 45, 60 minutes or custom - choose a focus mood (Lo-fi, Ambient, Energetic, Calm), and start. Minimal on-session UI keeps notifications and clutter out of your way so you can actually finish what you started. HABITS AND CHALLENGES THAT BUILD STREAKS Turn "I should meditate/read/exercise more" into a habit with a time slot, a goal, and a streak worth protecting. Join guided challenges like Morning Routine to build a new routine in days, not months, with daily check-offs and visual progress you can watch grow. SMART TASK PLANNING Add tasks with priorities, subtasks, and reminders, then let your AI companion help you plan the day, break down a task that feels too big, reschedule what slipped, or clear an overwhelming list - just by asking in chat. REFLECT AND RECHARGE End the day in your journal: log your mood, write a quick reflection, and get an encouraging response from your companion. It takes two minutes and turns "another day gone" into visible progress you can look back on. SEE YOUR PROGRESS ADD UP Weekly and monthly stats on focus time, task completion, streaks, and mood trends show you the pattern behind the good days - so you can do more of what's actually working. BUILT FOR - Students cramming focus between classes - Freelancers and remote workers who work alone and miss accountability - Anyone who has tried a to-do app, a habit tracker, and a pomodoro timer separately - and wants one that finally talks to the others - People who respond better to encouragement than streak-shaming WHAT'S INSIDE - Focus timer with mood-based music - Habit and challenge tracking with streaks - AI planning assistant for tasks, reschedules, and daily breakdowns - Mood journal with guided reflection - Weekly and monthly productivity statistics - Daily reminders that respect your schedule Free to start. Upgrade any time for unlimited focus sessions, deeper AI planning, and advanced stats. Less scrolling. More finishing. Start your first focus session today.

OpenDisplay turns your iPhone or iPad into a second display for your Mac. It's the open-source way to put your spare Apple device to work as a real extended monitor — drag windows onto it, keep chat, notes, or logs in view, and gain screen space anywhere you go. It's not a mirror: it's a genuine additional display your Mac treats like any other monitor. • Real extended display — arrange it in your Mac's Display settings and drag windows across • Connect over USB for the lowest latency, or over Wi-Fi with zero setup • Retina-sharp, pixel-for-pixel rendering • Touch and scroll — tap, drag, and two-finger scroll to control your Mac • Works in portrait or landscape • Private by design — a direct connection between your own devices, with no accounts, no servers, and no tracking IMPORTANT: OpenDisplay requires the companion OpenDisplay app for Mac, running on your computer on the same cable or Wi-Fi network. Get it at opendisplay.app — without it, this app has nothing to connect to. OpenDisplay is open source under the GPL-3.0 license.
