I built a short-video app for kids where every video is checked before kids see it (Android)

I'm a solo developer in Ghana and I just shipped KidsTok on Google Play. The idea: short videos for kids aged 0-12, but nothing reaches a child until it has been checked. There are no comments and no messages. A parent PIN, daily time limits, and a weekly email to parents listing what their child watched.

A few things that were harder than expected: making the feed play smoothly on cheap Android phones, building an offline "travel mode" that downloads videos ahead of time, and checking uploads for duplicates.

It's free to download, Android only: https://play.google.com/store/apps/details?id=com.kidstok.app

I'd love feedback from devs who are also parents. What would make you trust an app like this?
