Frequently asked questions

Which productivity apps should I install first?

Start with five, one from each core category, rather than downloading everything at once. Pick one task manager (say Things 3, Todoist, or TickTick), one notes app (Notion, Obsidian, or Apple Notes), one calendar (Fantastical or Google Calendar), one focus tool (Freedom or Forest), and one password manager (1Password or Bitwarden). This five-app starter kit outperforms fifty randomly chosen apps every time. The gain from any app only appears once it's invisible in your daily rotation, so add from the wider list only as specific frictions actually show up.

Is it worth installing all 50 productivity apps?

No — install five at a time, maximum. The article's core rule is that an app only pays off once it disappears into your daily rotation, and stacking dozens at once guarantees most stay unused. The fifty are organised by the problem each one solves, so treat the list as a menu rather than a checklist. Build the five-app foundation first (tasks, notes, calendar, focus, passwords), live with it, and only reach for another when you hit a concrete, repeating friction that your current set can't handle. More apps is usually more overhead, not more output.

What are the best task and project management apps for iPhone?

The strong options are Things 3, Todoist, OmniFocus, TickTick, and Microsoft To Do, with Sorted worth a look if you want a time-block planner. Don't overlook the built-in Reminders app either — it's better than it gets credit for and may be all a lighter user needs. The right pick depends on how much structure you want: Things 3 and Todoist suit most people, OmniFocus rewards heavier project systems, and TickTick folds in a calendar view. Choose one and commit rather than app-hopping, since the switching cost usually outweighs any feature edge.

Are the built-in iPhone apps good enough, or do I need third-party ones?

Several built-in apps hold their own and are worth trying before you pay for alternatives. Reminders is genuinely capable for tasks, Apple Notes covers most note-taking needs, and Voice Memos is reliable for quick audio capture. The case for third-party apps is specific friction — you want time-blocking, cross-platform sync, or a knowledge base like Notion or Obsidian. Start with the built-ins, notice exactly where they fall short for your workflow, and only then add a specialised app to close that gap. That approach keeps your setup lean and avoids paying for capability you won't use.

What apps help me focus and cut down phone distraction?

The focus category is where a small install pays off fastest: Freedom blocks distracting sites and apps across devices, Forest gamifies staying off your phone, ScreenZen and Opal add friction to habitual app-opening, and Session works as a focus timer. These tools work by raising the cost of the distraction just slightly above the cost of doing the actual work, which is often enough to break the unconscious habit loop. Pick one, since running several at once mostly creates overlap. Pair it with a single task manager and you've covered the two highest-leverage slots in any starter kit.
