OneThing
Read full descriptionHide full description
1Thing helps you cut through the noise and focus on what truly matters each day. The concept is simple: choose ONE important goal, lock it in, and give it your full attention. When you're done, close it with context — how much impact it had, how difficult it was. If you gave up, close it honestly and move on. ONE GOAL. NOT A LIST. Most productivity apps overwhelm you with tasks. 1Thing does the opposite — it forces you to ask: "What's the ONE thing that, if I do it today, makes everything else easier?" FEATURES · Set one meaningful goal per day · Lock it in with a two-question validation · Mark it as achieved or resigned with reflection · Weekly history to track your progress · Home screen widget (small and medium) · Daily reminders to define and close your goal · Motivational quotes to keep you focused · Beautiful, distraction-free design YOUR DATA. YOUR DEVICE. Everything stays on your iPhone. No accounts, no cloud, no tracking. Just you and your one thing. 1Thing — because less is more.

Verdict
The clearest difference is in-app purchases: OneThing at none against Zenith's 1. Zenith's advantage is update cadence (every 4 days vs every 6 weeks) and iOS requirement (18.0 vs 26.1). On price, ads and device support there is nothing between them.
