Developed by iOSGods, Sideloadly is a sideload utility for iPhone, iPad, and iPod touch.

However, macOS support is planned.

## Enterprise Certificates
Applications downloaded using Enterprise Certificates can be revoked randomly. As Apple continues to tighten rules for enterprise app ceriticates, often these certificates are revoked everyday, other times they can last for over 3 months. The following sites all use Enterprise Certificates to sign apps to your device for free.
* [appdb](https://appdb.to/) (allows you to easily reinstall all revoked apps with one button from [IPA Cache](https://appdb.to/my/ipa-cache))
* [Tweakbox](https://www.tweakboxapp.com/)
