NextThing for Getting Things Done

GTD (Getting Things Done) is David Allen's method for a clear head: capture every task, clarify what it means, and always work from a trusted list of next actions. Plenty of apps track tasks; few are real GTD apps that are also fast, native, and on every device. NextThing is. It guides you through your inbox one item at a time, and new AI fills in each task's project, context, energy, and due date. Native on iOS, Android, Mac, Windows, Linux. Offline-first. Free to start.
