Binaural Beat
APK
Binaural Beat is a binaural beat generator for relaxation, focus and sleep. A binaural beat is created by playing two slightly different frequencies, one in each ear. The brain perceives a third "beat" at the difference between them. Use headphones for the effect to work. Features: * Two audio engines: - Simple: a lightweight built-in tone generator with base and beat frequency sliders. - SBaGen: the classic Sequenced Binaural Beat Generator by Jim Peters, with 58 bundled preset sequences (brainwave states, focus levels, chakra progressions and more). * Independent background layer that mixes under the beats, with its own volume: - Pink and brown noise, generated on the fly. - Looping nature samples (river, train). * Clean, modern interface. This is a 2026 revival of an old project: the original was a native Android port of SBaGen via OpenSL ES. This version keeps the genuine SBaGen engine but runs it on a modern stack. Binaural Beat is free software, released under the GNU GPL v2. It builds on SBaGen by Jim Peters (GPLv2). Bundled audio samples are freely licensed (Creative Commons); see the project's CREDITS for full attribution. Note: binaural beats are not a medical treatment. This app is for relaxation and personal experimentation only.

Biometric Bypass
APK
Biometric Bypass is an Xposed module that makes face unlock feel instant by skipping the confirmation step Android enforces after biometric authentication. Even after your face is recognized, Android often shows a "tap to confirm" dialog before letting you through. This module removes that dialog system-wide, so a successful scan unlocks straight away instead of waiting for a second tap. It works by hooking into System UI, so the bypass applies everywhere, including banking and security-sensitive apps that would normally force the extra step. Requirements Android 10 (API 29) or higher An Xposed framework with libxposed API 101 support An AOSP-based or close-to-stock ROM (OEM skins like MIUI or One UI are untested and likely unsupported) A note on security Removing the confirmation step trades a little security for speed. With it enabled, anything that satisfies the biometric sensor, including a spoof or your own face while you are asleep, will unlock without the extra tap. Use it where that tradeoff makes sense for you.

Bitwarden
APK
Bitwarden is the easiest and safest way to store all of your logins and passwords while conveniently keeping them synced between all of your devices. Password theft is a serious problem. The websites and apps that you use are under attack every day. Security breaches occur and your passwords are stolen. When you reuse the same passwords across apps and websites hackers can easily access your email, bank, and other important accounts. Security experts recommend that you use a different, randomly generated password for every account that you create. But how do you manage all those passwords? Bitwarden makes it easy for you to create, store, and access your passwords. Bitwarden stores all of your logins in an encrypted vault that syncs across all of your devices. Since it's fully encrypted before it ever leaves your device, only you have access to your data. Not even the team at Bitwarden can read your data, even if we wanted to. Your data is sealed with AES-256 bit encryption, salted hashing, and PBKDF2 SHA-256. Bitwarden is focused on open source software. The source code for Bitwarden is hosted on GitHub and everyone is free to review, audit, and contribute to the Bitwarden codebase.
