About Yoakari: Screen Time Blocker
When you try to open an app you chose, a night town appears. Choose “Don’t open it” and one more window lights up. You can also choose “Open for 5 minutes.” Nothing is taken away — you simply don’t get a light. After five minutes the screen comes back. As lights add up, buildings appear: a bathhouse, an old bookshop, a café, a lantern alley, a lighthouse. You can name every building you build. ■ What you can do ・Choose which apps bring up the screen ・See how often you stopped and how often you opened, on a 7-day chart ・Collect 24 kinds of buildings, plus one that shows up only rarely ・Set the hours the screen can appear (one-time purchase) ■ Nothing is forced Yoakari never makes an app permanently unusable. Choose “Open for 5 minutes” and you can use it. It is one quiet beat, so the choice stays yours. ■ About your records Your counts and the names you give buildings stay on this iPhone. Nothing is sent to the developer. No account is required. There are no ads. ■ About the purchase “Opening Night” is a one-time payment. There is no monthly fee. The free version lets you choose one app and build six kinds of buildings.
