A New Way to Sideload

AltStore is an app store designed for sideloading. Every app in AltStore gets a beautifully generated store page with detailed information to make sideloading fun and easy. Browse apps from trusted developers, or add additional "sources" to further increase your options.

Plus, AltStore is made with security in mind. You can view a full list of an app's permissions from its store page, and AltStore will even automatically alert you if they change* so you can sideload with confidence.

*Permission checking coming later this year with AltStore 2.0

Self-Published Apps

Anyone can distribute their apps with AltStore. All you need is to make a “source”, which you can do by hosting a text file with basic information about your apps. Users can then enter your source URL in AltStore and your apps will automatically appear*

Follow our complete guide to create your own source and start distributing your apps in minutes!

*Custom sources coming later this year with AltStore 2.0

“[AltStore] is clever, has been verified by other developers, and the service has an active community of thousands of users who side-load apps on their devices. For the past few weeks, I’ve been one of them.”

Experience Apps like Never Before

AltStore allows apps to exist on iOS that may not otherwise.

Apple doesn't allow all apps on their store, so AltStore gives those apps a chance.
