What's new in v2.4.1
# The second email is now a paid feature.
As Boomerang welcomes more and more users, the maintenance of the app has become costly. To sustain development, I have decided to make the second email address feature a paid option. It's a one-time payment; I hope it's affordable for everyone. Please share your feedback using the form inside the app. Thanks for your support!
+ Fix bugs and improve performance.

How to install Boomerang : Email myself v2.4.1 on Android 5.1 Lollipop+
Takes about 2 minutes. You'll need roughly 7.1 MB of free storage.
- Grab com.boomerang.app_20403.apk — hit the Download button above (7.1 MB). If your browser warns about APK files, choose Keep or Download anyway — that warning fires on every APK, not just this one.
- Trust your browser to install — on Android 8+ go to Settings → Apps → Special access → Install unknown apps, pick the app you downloaded with (Chrome, Firefox, Files, etc.), and flip Allow from this source. On older Android, toggle Unknown sources under Security.
- (Optional) Verify the file — compute the MD5 of the downloaded APK and make sure it matches 8c055f95591e3b68…. Any difference means the file is corrupted or tampered — delete and re-download.
- Open the APK — tap the download notification, or find com.boomerang.app_20403.apk in your Files app under Downloads, then tap it. Android's package installer will appear.
- Check the signer — the install screen will name the publisher. For this build it should read CN=Thomas Kientz, C=FR. If it doesn't match, cancel — you have the wrong file.
- Review permissions & tap Install — scroll the permission list, then confirm. If Play Protect flags it, tap Install anyway (this APK was scanned as TRUSTED).
- Done — open Boomerang : Email myself — tap Open on the install screen, or find the Boomerang : Email myself icon in your app drawer.
