UN-ASIGN

What Happens When You Open It

Opening UN-ASIGN for the first time presents a login screen with no option to sign up directly. This immediately tells you the app is not for casual use — it is designed for volunteers and humanitarian workers who already have credentials or are registering through the UN system. The interface is clean and minimal, with a simple color scheme that reflects the United Nations branding. Below the login fields, there is a TEST-switch, which allows users to test the app without sending real data to the UNOSAT servers. The app does not ask for any permissions during the initial launch, which is surprising for a camera-based app. It simply waits for you to enter your credentials and tap the login button.

Once logged in, the main screen displays a camera viewfinder with buttons to take a photo, add text, and send. The layout is functional rather than flashy. Each button is clearly labeled, making it easy for users in stressful situations to capture and send images quickly. The app does not push notifications by default; you have to enable them in the settings. This might be a deliberate choice to avoid overwhelming users with alerts. The overall feel is that of a utility tool rather than a polished consumer app. The developers at AnsuR have prioritized function over form, which makes sense for a disaster response app where speed and reliability matter more than visual appeal.

How Photo Compression and what3words Work Together

The photo compression feature and the what3words location system are two of the most important features of UN-ASIGN, but they are not explicitly detailed on the Play Store page. What is not obvious is how these two features interact in a real disaster scenario. The app compresses photos significantly to save time, cost, and bandwidth — up to 99% savings according to AnsuR. This means that even in areas with poor network connectivity, volunteers can send high-quality images that are essential for damage assessment. The what3words integration then adds a precise location to each photo, allowing UNOSAT to pinpoint exactly where the damage occurred. This is a powerful combination: the compression ensures the data gets through, and the location system ensures it is useful.

The what3words system divides the world into 3m x 3m squares and assigns each a unique three-word address. This is much easier to communicate than GPS coordinates, especially in areas where addresses are not well-defined. When a volunteer takes a photo, the app automatically adds the what3words address to the metadata. UNOSAT can then overlay these photos on satellite imagery to assess damage more quickly and accurately. This workflow is not described on the Play Store page, but it is confirmed by external sources. The integration between compression and location addressing is what makes UN-ASIGN a practical tool for disaster response.

Real-World Performance: What the Data Shows

The app has a very small user base, with no visible ratings on Google Play or the App Store. This suggests it is used exclusively by UNOSAT volunteers and humanitarian workers, rather than the general public. The Android version is relatively lightweight at 46.4 MB, while the iOS version is slightly larger at 53 MB. The app does not display ads, which is a positive point for a free app. The developer states that data is encrypted in transit, and no data is shared with third parties. This is a strong privacy statement, especially for an app that handles sensitive disaster information.

The version history shows a pattern of regular updates, with version 2.1.7 released in February 2026 and version 2.1.5 released in March 2025. The changelog for 2.1.7 includes fixes for edge-to-edge display issues, updated password requirements, and the removal of the "display over other apps" permission. This suggests the app is actively maintained and responsive to user feedback. The app supports Android 6.0 and above, which covers a wide range of devices. Overall, the app appears stable and functional, though the small user base makes it hard to gauge its reliability at scale.

The Permission That Raises a Question

The WRITE_EXTERNAL_STORAGE permission is worth a closer look because it is not typical for a camera app. This permission allows the app to modify or delete the contents of your shared storage. For a disaster response app, this might be necessary to save photos locally before sending them, especially in areas with intermittent connectivity. However, it also raises privacy concerns, as the app could potentially access other files on the device. The WAKE_LOCK permission is also notable, as it allows the app to prevent the phone from sleeping during photo uploads. This is a reasonable permission for an app that needs to ensure data is sent successfully, even in challenging network conditions. The VIBRATE permission is used for haptic feedback, which might be helpful for users in noisy environments. These permissions are documented in the Exodus privacy report, but they are not listed on the Play Store page. This lack of transparency is a concern for users who want to understand what data the app accesses.
