RestBud

A schedule-style screen-time manager for parents, installed on your child's iPhone or iPad. Built-in Screen Time is a blunt tool. RestBud adds seven things it can't do: โข Lock schedules โ apps you add to a Lock are blocked all day by default; check weekdays and set one or more unlock windows (say, 7:00โ12:00 plus 14:00โ16:00 on Mon/Wed/Fri) and they open and close automatically. โข Rest cycles โ apps you add to a Rest must take a break (say, 5 minutes) after the play time you set (say, 30 minutes), then unlock automatically, on repeat. โข Daily limits โ put several apps on one list and give them a shared daily total (say, 1 hour across three games); once it's used up they all lock until tomorrow, and the parent screen shows roughly how much has been used today. โข Website allow list โ turn it on and only the sites you list open (say, YouTube and school sites); everything else is blocked, and your child can see the allowed sites on the home screen. โข Ask for more time โ when an app is locked, your child can tap "Ask for 10 more minutes"; approve it on the RestBud home screen and only that app opens for 10 minutes, then locks again. No arguing, no waiting around. โข Device protections โ one switch each for built-in iPhone restrictions: no deleting or installing apps, no in-app purchases, date and time locked to automatic, adult websites blocked. No more digging through Settings. โข Your family's voice โ when time is up, your child hears a recording of you, not a cold alarm. The blocked screen is a gentle sprout illustration that even tells your child what time they can play again โ not a scary blocking page. โข Set it once and it runs itself: rules are enforced by the system scheduler, even if the app is closed โข A parental gate protects all settings โข Deletion protection: turn it on and your child can't delete RestBud โข Completely free, no account, no ads, no data collection โ everything stays on this device; a voluntary tip jar lives behind the parental gate RestBud is built on Apple's official Screen Time technology.

Verdict
The clearest difference is in-app purchases: Popusign at none against RestBud's 3. Popusign also leads on iOS requirement (15.0 vs 17.0). RestBud's advantage is update cadence (weekly vs every 5 weeks). On price, ads and device support there is nothing between them.
