Editor's Overview

Banana Split is a system application developed by mezinster, packaged as a single Android APK of version 0.9 weighing in at 28.99 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 28.99 MB, so it installs quickly even on modest connections.
This build is signed by "mezinster" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

Banana Split uses Shamir's Secret Sharing to split secrets into QR-code shards. Any majority of shards can reconstruct the secret — fewer reveal nothing.

How it works

1. Enter your secret (e.g., a seed phrase, private key, password).
2. Choose how many shards to create and how many are required to reconstruct.
3. Use the auto-generated passphrase or enter your own.
4. Banana Split encrypts the secret with the passphrase, then splits the ciphertext into N QR codes using Shamir's scheme.
5. Print or save the QR codes. Write the passphrase by hand on every sheet.

To reconstruct: scan a majority of QR code shards, enter the passphrase, and your secret is restored.

Features

• Offline — all cryptography happens on-device, no server communication
• Save shards as PNGs or PDF with full Unicode font support
• Camera and gallery QR scanning with multi-file import
• Custom or auto-generated passphrases
• User-selectable quorum (how many shards needed)
• 8 languages: English, Russian, Turkish, Belarusian, Georgian, Ukrainian, Polish, Spanish
• Cross-platform shard compatibility with the Banana Split web app

Security

Encryption: scrypt key derivation + NaCl secretbox (XSalsa20-Poly1305).
Splitting: Shamir's Secret Sharing over GF(256).
No data collection, no analytics, no trackers.

Frequently Asked Questions

Is Banana Split free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Banana Split require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Banana Split safe to install?
We link to the exact APK published by mezinster. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Banana Split?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
