Relay is a task, project and goal manager built for Getting Things Done. You capture anything into one Inbox, and Relay asks the questions GTD asks to clarify each item: is it a next action, a project, something you are waiting for, or something for later? Relay never files anything for you....

As answered by people managing Relay GTD and Splitwise.
Relay GTD's answer
Relay is built only for Getting Things Done, and it runs the whole method on every device: native apps for iPhone, iPad, Mac, Android and Windows, plus the web. The weekly review is a guided twelve-step sequence rather than a reminder to review, the Clarify wizard asks the GTD questions one item at a time, and projects link up to areas, goals, vision and purpose. Most GTD apps either run only on Apple devices or leave the method for you to build out of lists and tags.
Relay GTD's answer
People who practise Getting Things Done, or want to, and use more than one kind of device: a Windows PC at work and an iPhone, or an Android phone and a Mac. Many have tried GTD in a general task app and found themselves maintaining the system instead of using it.
Relay GTD's answer
Relay is built by one developer in Switzerland. The best-known GTD apps run only on Apple devices, and the cross-platform ones leave the method for you to assemble from lists and tags. Relay set out to be a complete GTD system that works the same on every device, with the weekly review built in. It was released in 2026, on the web first, then on Android, iPhone, iPad, Mac and Windows.
Relay GTD's answer
Flutter and Dart for the apps on all six platforms from one codebase. Firebase (Firestore, Authentication, Cloud Storage and Hosting) and Cloud Functions in TypeScript, all in Google Cloud's Zurich region. Swift for the Apple widgets and share extension, and Kotlin for the Android widgets. RevenueCat with the App Store, Google Play and Stripe for subscriptions, Mailgun for email to Inbox, and Google's Gemini API for the optional AI prompts.
Relay GTD's answer
Relay is for anyone who uses GTD on their own, and for a family, a couple or a small team sharing a workspace: up to ten people, each with a Relay account of their own.
Relay GTD's answer
If your devices are not all Apple, Relay gives you one GTD system across Windows, Android and the Apple apps. If you keep skipping the weekly review, Relay walks you through it step by step. It syncs both ways with Google Tasks, Microsoft To Do, Todoist, Notion and Linear, and with Apple Reminders on Apple devices, so the apps you share with other people can stay as ways in. Everything lands in the Inbox first and nothing is filed for you. If you want a free plan or a one-time price, other apps will suit you better.
