Free tools for Android and iOS builds
Quick checks for the questions that come up right before a release. Drop in your build and get a straight answer. No account needed.
Android
For .apk and .aab files
Target API Level Checker
Will Google Play accept my update?
Reads targetSdkVersion from your build and checks it against Play's current rule.
Google Developer Verification Checker
Is my app registered with Google?
Pulls the package name and signing fingerprint, then asks Google if the pair is registered.
APK Inspector
What's actually inside this APK?
Version, permissions, SDK levels, signing and ABIs, without installing it.
AAB Inspector
What will Play build from my bundle?
Modules, splits, manifest and signing for an Android App Bundle.
iOS
For .ipa files and Apple devices
IPA Inspector
Which devices can install this IPA?
Bundle ID, version, provisioning profile, expiry and the devices it covers.
UDID Checker
What's my iPhone's UDID?
Find the UDID of an iPhone or iPad from Safari, no Mac or cable needed.
The checkers open your file inside your browser tab and read only the parts they need. The build itself is never uploaded, stored or logged, so you can use them on builds nobody outside your team is meant to see. File size doesn't matter either.

Tell us what you keep checking by hand and we'll look at building it next.
Build checks out?
Upload it to App Dropper and send testers a link they can tap to install.
