Real-World Performance
I tested SealX Downloader on a Redmi Android phone for two days with normal download tasks. The main screens were easy to move through, and I did not notice serious lag while browsing the app. The download progress was easy to follow, although ads can interrupt the process and make the experience less pleasant.
During the test, the app did not show major crashes or serious UI bugs. Battery use was reasonable during short downloads, but long downloads naturally kept the network and screen active. The Redmi phone did not become unusually hot during normal use, though larger files and longer download sessions can put more work on the phone.
Recent Google Play reviews also show that some users have noticed changes in available video resolutions after recent updates. This means the quality choices you see can depend on the current app version and the source website.
Space & Safety
The latest version, 2.3.1, was updated on June 29, 2026. Third-party app listings report an APK/XAPK size of about 79.6 MB to 84.5 MB, depending on how the package is measured, so the exact Play Store download size can vary by device.
The installed app will use more storage than the download package. Your downloaded videos, photos, GIFs, and audio files can add much more space over time.
The app needs internet access to download online media. It also needs access to phone storage or media so it can save and manage downloaded files. Permission details can vary by Android version and phone model.
Google Play says the developer declares that no data is shared with third parties. It also says the app may collect app activity, app information and performance, and device or other IDs, with data encrypted during transfer.

Its feature list is useful for people who want one app for several types of media downloads.
