Install Apps without connecting the device to a computer: open the Diawi link provided by your app developer in Safari when on iOS, or in Chrome/Android Browser when on Android.

Diawi works with iOS 4+ and Android 2+ devices: development, ad-hoc and in-house builds can be installed wirelessly with a single tap.

Installation of apps on iOS devices can be painful: provisioning profiles, device compatibility, ... Diawi installation page has a lot of checks implemented to help prevent or diagnose most common installation issues.

Links are private: no search or index. They can be password protected and strictly respect Apple's security rules with UDIDs and provisioning profiles.

If the iOS popup "Diawi would like to install…" did not appear, check that you don't already have the same app installed from the AppStore.

If an app with the same bundle identifier is already installed on the device from the AppStore, nothing will happen.

Delete the app installed from the AppStore to be able to install this one.

After tapping the "Install" button in the popup, if nothing seems to happen and you are on this page, check your device's home screen: the installation should be in progress: you should see the icon of the app somewhere and a progress indicator.

If an "Unable to download app" popup appears after some time, first check your internet connection, and be sure that your device is not behind a firewall that may prevent downloading .ipa files.

Sadly, iOS won't give any detailed information on what went wrong. Check on the previous page if there are any warnings. Most common installation issues are:
- expired provisioning profile
- device's UDID not in the provisioning profile
- incompatible device (minimum iOS version, device family, required device capabilities and supported architectures)
- device has not enough space left

Starting from iOS 9, the developer has to be trusted by the device, otherwise a popup will appear and prevent using the app.

On iOS 9.0/9.1, go to Settings > General > Profiles > tap on the developer's profile, and tap on Trust.

On iOS 9.2+, go to Settings > General > Device Management > tap on the developer's profile, and tap on Trust.

Contact your app developer, so they can double-check the app and provide you with support.

By default on Android devices, installation is not allowed from "unknown source", in other words from sources/sites other than the Play Store.

In order to install an app from Diawi, it must be allowed through the following setting on the device:
in the Settings app, depending on the device and Android version, it could be in Security or in Applications, check the box "Unknown sources".
