Yes, AppSender is 100% free and also AD free. If you like it, please submit a review on Google Play.
AppSender requires Android 2.2 or higher. Its been tested on ARM based Android 2.2, 2.3, 3.0, 4.0 and 4.1. It does not contain any native code, so in theory, it should run on any hardware.
I get this question a lot. Root is not required.
It depends on the email app. Some email app will display "Install" button next to attachment. If not, save the APK file attachment to your SDCARD. Then launch the APK file to start the install using a file manager to install app.
Click on the download link. If you are using default browser, the app (APK file) will be downloaded to your download folder and can be accessed by launching the "Download" app.
The app download is only valid for 60 minutes. After 60 minutes, the app will automatically be deleted from our cloud server. We currently do not offer the option to extend this limit.
This is dependent on the mail app and/or service provider, not AppSender. "Email attachment" is likely to fail on large apps. For large apps, try using "Cloud Server" feature.
Very large. Its currently 10GB (10,000 MB) per upload. There no limit on number of upload.
AppSender uses http protocol to upload files to the "Cloud Server".
If you have other questions, please email firstname.lastname@example.org. I will try my best to answer them.
