Free on Google PlayWhy: One of the most used (10M+ installs) and praised productivity apps on the Google Play, Chrome Web, and Apple App stores
What it can do:
- essentially a gamified productivity timer:
- plant a tree and set a duration of time where you want to focus and not use your smartphone / distracting websites (Chrome)
- If you stay focused without getting distracted before the time is up, you’ll get a beautiful, healthy tree; if you cannot resist using your phone, your tree will die
- grow your personal forest over time by being focused
Cons: Some people might not find it motivating.
Try it:
Price: Free (in-app purchases)
Why: The most highly rated and reviewed alternative to Forest on the Apple App store
What it can do:
- similar to Forest: (1) plant a tree and set a duration of time where you want to focus and not use your smartphone, (2) if you commit to your task without getting distracted before the time is up, you’ll get a beautiful, healthy tree; if you cannot resist using your phone, your tree will wither, (3) unlock new trees over time by succesfully focusing
- multiple people can sync with each other and grow trees together
Cons: Some people might not find it motivating.
Try it:
Why: No need to install anything, it’s a simple systems setting
What it can do:
- app icons and notifications markers are designed to be eye-catching - putting your phone in grey scale can tone down their allure.
- Note that for this to be useful, you need to be able to toggle it on and off easily, because you will want to turn colour back on for some functionality (like maps)
Cons: Might be tedious to toggle on and off, when colour is needed.
Try it:
- on iPhone / iPad with a Home button, set a triple-tap on the Home button to toggle grey scale on and off, by going to: Settings > Accessibility > Accessibility Shortcut > Colour Filters
- on iPhone / iPad without a Home button, set a double tap on the back of your phone to toggle grey scale on and off, by going to: Settings > Accessibility > Accessibility Shortcut > Touch > Back Tap -> Double Tap > Accessibility Shortcut
- on Android (v11+) add a gray scale toggle to your quick settings: (1) from the top of your screen, swipe down twice, (2) at the bottom left, tap Edit (3) touch and hold the grayscale symbol, then drag to where you want it
Why: No need to install anything, it’s simply about organising your device layout.
What it can do:
- arrange your apps so that the home screen is minimalistic and simple, and the apps you want to use less often require a bit more effort to get to.
- for example, try limiting your first page of apps to only apps you use for quick in-and-out tasks - move the rest, especially those you find yourself using mindlessly, off the first page and put them in folders
Cons: None.
Try it:
- if you normally open apps by searching for them, then you can stop that app from showing up in search, such that you instead have to go find it where you placed it on your phone
iOS: go to Settings > scroll down to the relevant app (e.g. Safari) > Siri & Search > turn off ‘Show App in Search’ and ‘Suggest App’
Price: ~$10 on Apple App Store
Why: Loads of critical acclaim in tech magazines and very highly rated on the Apple App Store
What it can do:
- choose how long you want to write (5, 15, 30 min), then enter a flow session.
- if you exit early, or stop typing for longer than five seconds, all progress is lost
- the only way to save your work is by writing until the timer ends.
- in this way, the app forces you into a state of flow
Cons: Only useful for specific writing purposes.
Try it:

Safari
Harsh but effective way to quickly get in a writing flow
Price: Free
Why: Positive reviews in magazines from Wired to Lifehacker; nothing to install - just visit it in your web browser
What it can do:

- very useful in those writing situations where you just need to bash out a rough draft, which you will then edit afterwards
Cons: Only useful for specific writing purposes.
Try it:
- go to the website, set a time or word goal, then begin typing
