The app WAMR: Undelete messages! by drilens null is free to download, allowing users to rescue their deleted messages without any initial cost. However, like many free apps, it does include advertisements that may appear while you are using the app. These ads are a part of the free version's revenue model. Fortunately, they don't interrupt the app's primary function and are typically easy to dismiss.

While no direct in-app purchases or subscriptions are necessary to use the primary features, additional features or an ad-free experience may require a purchase. Be sure to check the app's settings or any prompts for optional upgrades to enhance your user experience, though these are not required for the basic use of the app's core functionalities.

Installation on iOS Devices: Unfortunately, WAMR is currently only available for Android devices. iOS users will need to look for alternative apps in the Apple App Store with similar functionalities, as this specific app is not supported on iOS devices yet.

Installation on Android Devices: To install WAMR, ensure that your Android device is running on version 5.0 (Lollipop) or above for optimal performance. Open the Google Play Store, and enter "WAMR: Undelete messages!" in the search bar. Locate the app developed by drilens null and select 'Install' to begin downloading. Once downloaded, open the app and grant the necessary permissions, such as access to notifications, so the app can function correctly. Review the app's privacy settings to ensure your preferences are selected before starting to use the app.

Step 1: Upon opening WAMR for the first time, you'll be greeted with a brief introduction to its capabilities. Tap on 'Next' until you reach the 'Select Apps' page.

Step 2: Here, choose the messaging apps from which you want to recover deleted messages. Confirm your selections by tapping 'Next.'

Step 3: You will need to grant the app access to notifications. This is crucial as it allows WAMR to monitor incoming messages and detect if any are deleted. Follow the on-screen instructions to proceed.

Step 4: Navigate to the 'Settings' option within the app if you want to customize your experience further. You can adjust notification settings for specific apps and manage app permissions comprehensively.

Step 5: To view recovered messages, open WAMR and tap on the app you chose during setup. The recovered messages will be displayed chronologically. Tap on a message to view its details or browse through conversations.

Tip 1: Enable the 'Auto-Save Media' option in the settings. This ensures that any media files received from supported apps will be automatically stored for future recovery. It's especially helpful for recovering images or voice notes that might otherwise be lost.

Tip 2: Regularly review the permissions you've granted to WAMR. Keeping these up to date will not only enhance security but also ensure the app functions optimally without any permission conflicts with other apps.

Tip 3: Make use of the app's notification filters. Many users receive a barrage of messages across different apps; using filters helps in categorizing notifications, making it easier to track and recover specific messages without sifting through irrelevant ones.
