The five steps
The whole GTD method, faithfully
Trayzero walks David Allen's five steps end to end — not a loose to-do list with GTD sprinkled on top.
- 01
Capture
One-tap capture from anywhere — a floating button, voice-to-text, the share sheet, or a home-screen widget. Get it out of your head fast.
- 02
Clarify
A card-stack Process Inbox flow walks the full GTD decision tree — actionable? two-minute rule? delegate, defer, or drop — until your inbox hits zero.
- 03
Organize
Canonical lists: Next Actions, Projects, Waiting For, Someday/Maybe, Calendar, Reference. Projects are first-class with @-contexts and Areas of Responsibility.
- 04
Reflect
A 7-step Weekly Review wizard guides a scripted pass through every bucket, so nothing quietly rots at the bottom of a list.
- 05
Engage
See the right next action for right now — filtered by context, energy level, and the time you actually have.

In-depth comparisons: Trayzero vs Everdo · Trayzero vs Things 3 · Trayzero vs OmniFocus
Privacy you don't have to think about
Your tasks never leave your device
No account. No task servers. No in-app tracking. SQLite under the hood, JSON backup in your hands — and the app is open source, so you can verify all of it yourself.
Proof points
Real product facts, not borrowed trust
Trayzero is new, so the site sticks to what can be verified from the shipped app and its architecture.
No account
Nothing to sign up for. Open the app and start.
No cloud
Everything is a local SQLite database in the app's private storage.
No in-app tracking
The app has zero analytics SDKs. Crash reporting is opt-in and off by default.
Live on Android & iOS
The app is in production on Google Play and the App Store, so anyone can install it without a beta invite.
Local SQLite storage
Tasks, projects, contexts, areas, and reviews live in the app's private on-device database.
Plain JSON backup
Export and import a Trayzero backup file whenever you want, without depending on a Trayzero account.
Open source (GPLv3)
The full app source is public on GitHub — audit every line and verify the privacy claims yourself, instead of taking them on faith.
Inside the app
A GTD system you can actually see
The app is organized around the moments where task systems usually fall apart: fast capture, clear projects, and a review that keeps every list current.
Capture without breaking stride
Add the thought now, decide what it means later. Trayzero keeps capture fast so your inbox can become the trusted entry point.
Keep projects moving
Projects, next actions, contexts, and areas stay connected, so the system reflects real commitments instead of scattered task lists.
Review before things drift
The Weekly Review turns maintenance into a guided pass through your system, with progress that is visible from start to finish.
Questions
Frequently asked
Is Trayzero really free?
Yes — every feature is unlocked, with no ads and no account. If you'd like to chip in, there's an optional tip jar and a cheap Supporter subscription, but those only add cosmetic extras like a supporter badge — never any part of the GTD workflow.
Where is my data stored?
On your device, in a local SQLite database. There is no Trayzero server and no cloud sync. You can export and import a plain-JSON backup any time.
Which platforms are supported?
Both are live — Android on Google Play and iOS on the App Store.
Do I need to know GTD to use it?
No. The Process Inbox flow and Weekly Review wizard guide you through the method step by step — it's a good way to learn GTD by doing it.
Is Trayzero open source?
Yes. The app is open source under the GPLv3 license, with the full code public at github.com/roman10/trayzero. You can read it, audit the privacy and on-device claims, and even build it yourself.
Is this affiliated with the David Allen Company?
No. Trayzero is an independent app inspired by the GTD methodology. "Getting Things Done" and "GTD" are trademarks of the David Allen Company.
