Cleaner & security app for Android
A small supernova for the clutter on your phone.
Supernova finds app cache, leftover APKs, duplicate photos and forgotten large files, and checks your apps and Wi-Fi while it is there. You see every file first. Nothing is deleted until you tick it.
Demo scan on this page. Real results depend on your phone.
On the home screen
Nine tools, each one tap away
Junk File Cleaner
Finds cached data and temporary files that apps leave behind.
Antivirus
Checks installed apps and APK files for known malware.
Deep Scan
Looks for empty folders, old screenshots and leftover APK files.
Large File Manager
Lists your biggest files, largest first, so you can decide what stays.
Duplicate Photos
Groups repeated shots so the gallery keeps one of each.
Compress Photos
Makes image files smaller when you want to keep the picture but not its size.
Social Media Cleaner
Finds images, videos and cache piling up in messenger and social app folders.
Battery Analyzer
Shows battery health, temperature and charge level.
Wi-Fi Security Check
Shows how nearby networks are encrypted, so open or weak ones stand out.
You stay in charge
Nothing goes until you tick it
Every scan ends with a list, not with a deletion. Supernova shows what it found, how big each file is and where it lives. You pick the files; the app removes only those, and only after you confirm.
Try the list on the right: the button counts your ticks.
Your data
What stays on the phone, and what leaves it
Stays on your phone
- Your files. Cleaning, deep scan, duplicates, large files and compression all work on the device, including the background check that tells you when junk has built up. Your photos, videos and documents are not uploaded.
- Wi-Fi details. Network names and encryption types are read to grade nearby networks. Android asks for location permission before any Wi-Fi scan; the app does not use it to find where you are.
- Battery readings. Health, temperature and charge level are shown, not sent.
Leaves it, for a reason
- App fingerprints, for the antivirus. Package names, signatures and file hashes of installed apps and APK files go to Trustlook’s cloud scanner, which compares them with known threats. The app asks before the first scan.
- Usage counts and crash reports. Firebase receives which screens and buttons are used, with no file or network names attached, and a report when the app crashes.
- Ad data, when ads are shown. Ads come from Google AdMob, which receives your advertising ID and basic device information. In the EU, EEA and UK the app asks for your consent first.
Details, retention and your rights are in the Privacy Policy.
