+title: Installing apps on SmartDust Lab devices
+---
+SmartDust Lab provides features for fast and convenient installation of applications on Lab devices. 
+Both Android and iOS platforms are supported.
+
+To access the installation features, go to the main page of the SmartDust Lab and select a device to control.
+Select the "Dashboard" tab if you're not already there.
+To the right of the device's screen, look for the tile labeled "Install App".
+
+## Android
+You need to have your app in the APK format.
+### Uploading from your computer
+Click on the "Drop file from your computer" button and select the APK file from your computer.
+A progress bar will let you know about the installation status.
+After the installation has been completed, an app details window will appear, allowing you to launch the app or uninstall it.
+### (Custom feature) Uploading from a preconfigured storage
+If your private SmartDust Lab instance has been set up with a private storage, you can upload the APK file from there.
+Click on the the button labeled "Install from private storage [storage_name]".
+A dialog will appear, allowing you to view and install files from the configured storage.
+
+## iOS
+It is required for your app to be in the IPA format.
+Like all iOS apps, it needs to be signed with a valid provisioning profile for the specific Lab device you want to run it on.
+You have 2 options regarding the signing:
+1. You can sign the app yourself using your own Apple Developer account and a provisioning profile that includes the UDID of the Lab device.
+2. You can run your app through our special signing service.
+
+Once you have a properly signed IPA file, you can upload it to the Lab device in the same way as for Android apps.
+
+### Signing your app yourself
+You need to know the UDID of the Lab device you want to run your app on.
+On the main page of the SmartDust Lab it should be visile in the "Details" tab in the column named "Serial".
+You can also find it when you're using the device on the device control view in the "Info" tab, in the "Hardware" section.
+
+Then you need to add the device UDID to the provisioning profile you will use to sign the app.
+Refer to the official Apple documentation, e.g. [https://developer.apple.com/help/account/devices/register-a-single-device](https://developer.apple.com/help/account/devices/register-a-single-device)
+You can automate the signing process using [Fastlane](https://docs.fastlane.tools/)
+
+### Using our signing service
+You can use our signing service to sign your app with SmartDust's provisioning profile that works on all Lab devices.
+For that, use the POST endpoint at `https://[instance_name].smartdust.me/s/apk/resign`, e.g. `https://public.smartdust.me/s/apk/resign`
+You need to send your IPA file in the request.
+The response will contain the signed IPA file.
+
+Example using a shell tool `curl`:
+```bash
+curl -X POST -H "Accept: application/octet-stream" -F "file=@/path/to/your/app.ipa;type=application/octet-stream" https://public.smartdust.me/s/apk/resign -o resigned.ipa
+```
+Just replace `/path/to/your/app.ipa` with the actual path to your IPA file.
+You might also need to adjust the URL if you're using a private instance of SmartDust Lab.
+The signed IPA file will be saved as `resigned.ipa` in the current directory.
