Thoughts Left is a brain dump app for people who think too much: late-night spirals, half-finished ideas, things you keep checking, things you're scared to forget. Get them all out fast, before the mental clutter takes over. Capture however it comes to you. Type it, speak it as a Spoken Thought, or snap it. No structure required, no "right way" to do it. Then decide on your own time. Turn thoughts into a task or a note, or simply let them go with one swipe, because not every thought needs to become something.

UnTask helps you focus on just one thing. No lists. No timers. No pressure to be productive. UnTask is a single-task app designed to help you stay present with what you’ve chosen to do — and nothing else. Instead of juggling tasks, it asks a simple question: What is the one thing you’re doing right now? ONE TASK AT A TIME UnTask shows only your active task. Finish it, and the next one is ready. Line up what comes before and after each task, break bigger work into subtasks, and write notes with Markdown. ORGANIZE WITH TAGS Write #tags in a task’s title or notes. Pick a tag list to focus on tasks that have any or all of the tags you choose. As you type, UnTask suggests matching tags and tasks you’ve already written. ON YOUR WRIST UnTask on Apple Watch shows your current task. Check it off and move on to the next, add tasks, pick a tag list, or archive a task with a swipe. A complication keeps your active task on your watch face. START FROM ANYWHERE Use UnTask on iPhone, iPad, Mac, and Apple Watch. Ask Siri or use Shortcuts to see your current task, add a task, complete it, or move on to the next. Home Screen widgets keep your active task one glance away. WORKS WITH REMINDERS Mirror a Reminders list in UnTask, so your tasks stay in sync with Apple’s Reminders app — and with everyone you share that list with. ARCHIVE, DON’T DELETE Archive tasks instead of deleting them, so finished work is still there when you need it. PRIVATE AND AD-FREE No accounts, no tracking, no ads. Everything stays on your device — or syncs between your devices via iCloud. UNTASK PREMIUM Free: up to 3 open tasks. Premium unlocks: - Unlimited open tasks - Tag lists - Reminders mirroring - iCloud sync Choose a monthly or yearly subscription with a free trial, or a one-time lifetime purchase, and share it with your family through Family Sharing. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. UnTask isn’t about doing more. It’s about doing less — better. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
