As answered by people managing Trayzero.app and TickTick.
Trayzero.app's answer
Trayzero is the only GTD app that delivers the full Getting Things Done method on both Android and iOS — completely free, with no account and no cloud sync.
Most GTD apps make you choose between fidelity and privacy. Trayzero gives you both:
The closest local-first GTD competitor charges $99. Trayzero is free.
Trayzero.app's answer
Choose Trayzero if any of these matter to you:
vs. Todoist / TickTick — Those are cloud-synced task lists with GTD sprinkled on. Trayzero follows the full GTD method strictly, and your data never leaves your device.
vs. Things 3 / OmniFocus — Both are Apple-only and cost $50–$100+. Trayzero runs on Android and iOS, and it's free.
vs. Everdo — The closest comparison: local-first, strict GTD. But Everdo charges $99 for the mobile app. Trayzero is free and open source.
The short version: - You want real GTD, not a to-do list - You don't want your tasks in someone else's cloud - You don't want to pay for it - You use Android, iOS, or both
Trayzero.app's answer
Trayzero is built for knowledge workers and individuals who want to use GTD properly — not a simplified version of it.
The primary audience:
Trayzero works best for individuals managing their own work, projects, and commitments — it is not an enterprise or team tool.
Trayzero.app's answer
Trayzero started from a simple frustration: the best GTD apps were either locked to Apple devices, cost $80–$100, or weren't really GTD — they were generic task managers wearing a GTD label.
After searching for an app that faithfully implemented David Allen's full five-step method on Android, the answer kept coming back empty. So Trayzero was built to fill that gap.
The goal was straightforward: implement GTD properly, make it available on both Android and iOS, keep the data on the device, and charge nothing. No subscriptions, no accounts, no cloud servers holding your tasks.
Trayzero is an independent app — not affiliated with the David Allen Company — built by a solo developer who wanted a serious GTD system without the usual trade-offs. The source code is open, so anyone can verify the privacy claims or contribute.
Trayzero.app's answer
Trayzero is a native mobile app built for Android and iOS. Key technologies:
There is no backend server, no cloud sync infrastructure, and no third-party analytics SDK — by design. The simplicity of the stack is intentional: fewer moving parts means fewer ways for your data to leave your device.
Trayzero.app's answer
Trayzero is a free personal productivity app with no user accounts — so there are no named enterprise customers or B2B contracts.
The users are individuals: knowledge workers, students, developers, and GTD practitioners who want a private, local-first task system. Because no account is required and no data is collected, we don't have visibility into who uses the app beyond app store installs.
