Multiple strategies to reduce your screentime 1. Delay before opening your app: A bit of time before choosing if you need to open your distracting app. You can have the wait time increase each time you open your app. 2. Interrupt your scrolling: Check your distracting apps for short periods of time so you don't get sucked in. 3. Set an app goal and optionally block when you reach your limit. 4. Configurable for different days of the week and time by app. 5. Messages like "Is this important" before opening your app. 6. See your screen time for only your distracting apps. Don't worry about Google Maps bloating up your time. 7. Strict block your apps: Either for time ranges, after a certain number of opens or ScreenTime. 8. Locks on Settings to prevent you from changing your settings when you want to open an app. 9. Breathing and other activities to encourage you not to need to open the app while waiting for it to unlock. 10. Streaks to encourage you not to exceed your limits or override your settings.

ToDoSphere turns your day into something you can see. Every task is a sphere, and its size is the time it takes. A two-hour block is large. A ten-minute errand is small. Put them on one screen and you stop guessing whether your day fits — you can simply look at it. REBUILT FROM THE GROUND UP This version is a complete rewrite. The app opens faster, moves more smoothly, and holds up under a real workload. The idea has not changed. How well it works has. SEE WHAT ACTUALLY FITS A capacity bar shows planned time against the length of your day, so an over-booked day announces itself before you live through it. Set your own day length — nine hours is a default, not a rule. PLAN BY MOVING THINGS AROUND Drag spheres to arrange your day. Push one to the edge to send it to yesterday or tomorrow. Tap a sphere to change its duration, category or notes. COLOUR IS CATEGORY Every sphere takes the colour of its category, always. Rename categories, recolour them, and pick an icon from a wider set — so your day is readable at a glance rather than after reading. KEEP WHAT REPEATS Save a day's tasks as templates and stamp them onto any other day. Mornings that look alike should not be typed out twice. A REMINDER THAT SUITS YOU One daily nudge to plan, at a time you choose, and one switch to turn it off. No stream of alerts for individual tasks. SEE YOUR CONSISTENCY Completed tasks, your planning streak, and where your time actually goes by category — real numbers from your own data, not encouragement invented for you. SIGN IN YOUR WAY Use your email, or sign in with Google or Apple. FREE AND PRO Free covers five tasks a day and one saved template. Pro removes the limits, adds custom categories, and supports the work. Premium is an auto-renewing subscription. Payment is charged to your Apple ID at confirmation of purchase, and renews unless auto-renew is turned off at least 24 hours before the end of the period. Manage or cancel in your account settings.

Verdict

The call

The clearest difference is rating: ScreenZen at 4.9 against ToDoSphere's 4.0. ScreenZen also leads on ratings volume (52K vs 1) and chart position (#164 vs unranked). ToDoSphere's advantage is iOS requirement (14.0 vs 16.4). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. ScreenZen sells 4 one-off in-app purchases and ToDoSphere sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

ScreenZen holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: ScreenZen has 52K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 93% of ScreenZen's written reviews are positive against 100% of ToDoSphere's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ScreenZen ships an update every 3 weeks, ToDoSphere every 2 weeks. The most recent releases landed on October 23, 2026 and October 19, 2026 respectively.
