About this app

🔌 Ultimate USB – USB Manager & Bootable Creator
Turn your phone into a PC repair shop: bootable USB drives, formatting, partitioning, drive tests and retro game tools — over a simple OTG cable.

Nearly everything works WITHOUT root (only the internal SD slot needs it), on real native FAT16/FAT32/exFAT/NTFS/EXT2/3/4 drivers.

🛠️ BOOTABLE USB & IMAGE WRITING
• Ventoy (Unofficial): multi-boot USB — many ISOs on one drive, pick at boot. Install, update or clean it, with Secure Boot support, 4K alignment, MBR/GPT and FAT32/exFAT/NTFS. Copy ISOs over, or download them straight to the drive.
• ISO Burner (ISO2USB / DROFUS): Windows 7–11, Linux, Apple DMG, Raspberry Pi, MS-DOS, FreeDOS.
‣ Windows customization: bypass TPM 2.0 / Secure Boot / 4GB RAM, skip the Microsoft account, create a local account, turn off BitLocker, data collection and forced Copilot/OneDrive/Outlook, copy your regional settings, "Windows CA 2023" bootloaders.
‣ Windows To Go: a full portable Windows that boots and runs from the drive itself.
‣ Linux persistence: keep your files and changes between boots.
‣ High-speed mode, install.wim splitting for FAT32 / Secure-Boot PCs, MBR/GPT, cluster size, label.
• Raw Write (DD): write any image byte by byte, exactly as-is.

🧹 ADVANCED DISK MANAGEMENT
• Format USB: FAT16, FAT32, exFAT, NTFS, EXT2/3/4, with MBR/GPT, cluster size and label.
• Partition Wizard: create, delete, format, rename, wipe, back up and restore partitions, convert MBR ↔ GPT, with undo before you apply.
• Bad Blocks Check: write-and-verify scan that finds failing sectors and fake-capacity drives.
• USB Defragmenter: consolidate fragmented files on FAT32 and exFAT for faster reads.
• Wipe USB: permanently erase all data and partitions.
• Backup & Restore: full byte-by-byte image of the device.

🎮 RETRO GAMING TOOLS
• PS2 USB Utils: add, remove, rename, organize and export games. Direct copy or UL split, 4GB+ ISOs, OPL playlists, ul.cfg regeneration, split-game import, quick defrag, artwork downloads, plus PS1 (.VCD) import for POPStarter.
• PS3 ISO Tools: make ISOs from folders, extract, patch target CFW version, split for FAT32, join segments, auto-rename, [online]/[auto] tags, game info, SFO & icon extraction.
• Game Converter: ISO ↔ ZSO / CSO / CHD / VCD, BIN/CUE ➔ ISO or CHD, ZSO ↔ CSO, at max compression.

📁 FILES & STORAGE
• USB File Manager: copy, move, delete, rename, search and sort — and open drive files straight in other apps, with no copy to the phone.
• Partition Mounter: mount partitions, even hidden ones, into the Android Files app, read-only or read/write.
• Partition Image Manager: create, open and browse .img/.bk images.
• Archive Extractor: 7z, RAR, ZIP, ISO, TAR, GZip, BZip2, WIM, CAB, DEB, RPM and more, with passwords.

📊 DIAGNOSTICS & HARDWARE
• Device Info & Benchmark: vendor, product, serial, block size, plus sequential and random speed tests.
• Works with flash drives, portable SSDs, card readers and OTG hubs. HDDs are not officially supported (power limits).

💰 FAIR TOKEN SYSTEM
Almost everything is FREE. Only Ventoy install/update, ISO burning, formatting and the Partition Wizard cost tokens (1–3), earned FREE by watching one short ad.

👑 PRO VERSION
One-time lifetime purchase: no ads, no tokens, archive extraction straight to USB, full offline use.

⚠️ GOOD TO KNOW
• Keep the app in the foreground — operations pause when minimized to protect the drive.
• The free version needs internet for ads; disable ad-blockers and blocking Private DNS.
• Tokens live on your device: clearing app data or uninstalling clears them. Pro is tied to your account and stays safe.
• Drive not detected? Test it on a PC, try another cable, or reformat to FAT32.

Ratings and reviews

"All running processes are paused until the connection is restored." - Message you get when you don't have internet connectivity. Yeah... no, I don't need my USB formatter to be on the internet. Pass. To the developer: downloading apps actually requires an internet connection, formatting a USB drive does not. I would consider a paid version of the app that I could purchase through the Play Store (not by purchasing through the app).

there was a time when my computer went down and I had no way to fix it. But found this app and was able to create the medicat USB and save my computer and work projects that I would have lost without this. in the past I would see people complain about the coins like REALLY!! Lucky you can watch videos to get the services for free that would have cost me hundreds of dollars if I had to take it in. Great Job on the app and updates!!

It might work for certain .iso files and devices BUT if you don't have cold hard cash, and now, you had better get it right the first 9 ads it'll force you to watch... after that, you can only use the app if you pay $3+ each use. Doing this repeatedly will kill your USB. This app is a free command line utility repackaged and hosted in the Google Play Store. To call it overpriced is a massive compliment.
