Sago Mini School's 3 tactics

Advertise inside free kids games that match your age group

Surprisingly good on iOS; weak on Google Play, especially for the learning app

Run ads on game ad networks (Unity Ads, IronSource, AppLovin) in placements inside free-to-play apps that are close in experience and age demographic to Sago Mini. Gameplay trailers excite kids for the entertainment app. Focus spend on iOS.

Skip launching on Amazon because it costs as much work as iOS for far less return

Learning app still not on Kindle two years after launch

iOS, Google Play and Amazon/Kindle each take about the same time to build and QA, but impact is heavily skewed to iOS and Google Play. Amazon's Kids+ bundle (often included with cheap Fire kids tablets) further reduced the value, so Sago Mini reduced Amazon investment and never launched Sago Mini School there.

Aim ads for the learning app at parents and ads for the play app at kids

Shifting further toward parents for the learning app; no numbers

For the entertainment app (Sago Mini World), gameplay-trailer ads that excite the kid. For the educational app (Sago Mini School), which needs upfront buy-in from parents, ads are geared toward parents, and spend is indexing further toward parent marketing over time.
