GTD Apps Compared: iPhone, Android and Web (2026)
Updated · 3 min read · FrançaisDeutschEspañolItalianoNederlandsPolskiPortuguês (Brasil)Português (Portugal)
Choosing a GTD® app comes down to a few questions: does it carry the lists the method uses, does it help you review, does it go above the project level, does it filter next actions by context, time and energy, and does it run on the devices you own? This page compares six apps on exactly those questions, feature by feature.
A note on method: we make The Over Achiever, one of the six apps below. The table is built from what each vendor publishes on its own site — features and platforms as of September 2026 — not from our opinion of the others. Check each vendor's site for current prices.
