Say it. NextThing writes the task. Tap the mic, speak one sentence, and NextThing turns it into a proper task — due date, context, project and person already filled in. Or type a rough note and let AI clean it up. What used to take five taps now takes one. Underneath is a complete Getting Things Done system, so nothing you capture ever gets lost. Capture in seconds • Voice capture — speak, and the task writes itself • AI task parsing — turn a messy note into a structured task; keep the suggestions you want, drop the rest • Inline tags while you type — #context, @contact, ~project, !!priority • Forward an email straight into your inbox Clarify and organize, the GTD way • Guided inbox processing — one decision at a time, until your inbox is empty • Next Actions, Projects, Waiting For, Someday/Maybe and Scheduled lists • Areas of Focus — file every project under the part of your life it belongs to • Contexts and contacts — filter by where you are or who you're waiting on • Recurring tasks and deferred start dates • Checklists inside task descriptions Reflect, so the system stays trustworthy • A Weekly Review checklist that walks you through every list • Review reminders you'll actually keep Engage • Filter your next actions by context, time or energy — then just do • Calendar — add a task to your calendar, or subscribe to a live feed of everything scheduled • Search across every task and project Everywhere you work • iPhone, iPad and Mac, with a desktop app for your other machines • Offline-first — capture on a plane, it syncs when you land • Light, dim and true-black themes for OLED screens • Sign in with Apple supported Why GTD? Getting Things Done is David Allen's method, trusted by millions. The idea is simple: your head is for having ideas, not for holding them. Capture everything into one trusted place, decide what each thing means, and keep lists you'd actually look at. Less noise in your head, more finished work. Most to-do list apps let you write things down and stop there. NextThing gives you the workflow that turns a messy inbox into clear next actions — and a calm head. No setup weekend, no course to take. Open the app, say your first task out loud, and the workflow does the rest. Premium AI parsing and voice capture include 15 free suggestions every month. Premium makes them unlimited and adds Telegram quick-capture, email-to-inbox and the live calendar feed. Auto-renewing subscription, monthly or annual. Cancel anytime in your device subscription settings. Privacy: https://nextthinggtd.com/privacy Terms: https://nextthinggtd.com/terms

Trayzero brings David Allen's Getting Things Done (GTD) method to your iPhone. Free, no ads, no account, no sign-up. Your data lives on your device. Always. THE FIVE GTD STEPS, BUILT IN Capture - one tap, anywhere. A floating Capture button on every screen. Share anything from any app straight into your inbox. Voice-to-text for hands-free thoughts. A Home Screen widget for the fastest possible "add to inbox." Clarify - the killer flow. Process Inbox runs you through your captures one at a time, card-stack style. Each card walks the full GTD decision tree: actionable? Two-minute rule? Delegate? Single step or a project? When? Where? You hit inbox-zero faster than you thought possible. Organize - the canonical GTD lists. Inbox, Next Actions, Projects, Waiting For, Someday/Maybe, Calendar, Reference. Plus a real Project type with outcome, next-action warning, and Active / On Hold / Someday / Done / Dropped status. Seven default @-contexts you can extend (@phone, @computer, @errands, @home, @office, @anywhere, @waiting). Areas of Responsibility for the higher altitudes. Reflect - a Weekly Review wizard. A seven-step Friday review walks you through the canonical GTD pass: clear inbox, review next actions, check waiting-for, scan calendar, review someday/maybe, look at projects, set next week's intentions. Daily review supported too. Engage - do now. The Engage tab filters Next Actions by Context, Energy (low / medium / high), and Time Available (under 5m / 15m / 30m / 1h). Pull up the actions that match the moment you're in. REMINDERS THAT ACTUALLY WORK Due-date, defer-until, waiting-for follow-up, and weekly-review nudges fire as system notifications with action buttons - Done, Snooze, Move to Next Actions. Calendar two-way sync mirrors dated items into your system calendar. VOICE, PHOTOS, AUDIO Capture by voice. Attach photos or voice memos to any item. PRIVACY YOU DON'T HAVE TO THINK ABOUT - 100% on-device. SQLite under the hood. - No account, no servers, no analytics. - Crash reporting is opt-in and off by default. - Backup/restore as plain JSON: you own your data, you can take it anywhere. WHO IT'S FOR - GTD practitioners who want a clean, focused app that respects the method. - Anyone tired of cloud-syncing personal task data through someone else's servers. - People who want their tasks where their phone is - and nowhere else.
