Why these tools exist

The four things that trip up first-time Android publishers

After helping thousands of builders convert websites to Android apps, four problems come up again and again: a site that doesn't work inside a WebView, a package name that fails Google Play validation, no privacy policy, and icons sized wrong for the Play Store listing.

Each of these tools solves one of those problems — for free, in under two minutes, with no account required. They are the pre-flight checklist for your app before you hit publish on Google Play.

The tools are built and maintained by the same team behind Free App Maker, a no-code builder for Android apps from compatible published websites. Build free after email verification, then pay once to download the signed APK.
