OneMoreSecret is a decentralized secrets manager that leverages your smartphone's hardware keystore and biometric authentication to protect your passwords. Instead of relying on a cloud database, your sensitive data (e.g. passwords, TOTP tokens, files, and Bitcoin private keys are encrypted into QR codes or text payloads that can be safely embedded anywhere — even on a public wiki or plain text file.When you need to use a secret, you simply scan the code or tap the link with your phone, authenticate with your fingerprint to decrypt it locally, and the app acts as a virtual Bluetooth keyboard to instantly "auto-type" the password into your computer. This creates a seamless, air-gapped bridge that keeps your private keys entirely offline, protecting your credentials from keyloggers and cloud breaches while making cross-device authentication completely effortless.See project home page for detailed introduction and tutorial.

The use case for this app is creating reminders which are only relevant once in a time and they don't repeat such as reminders to go to the train on 15:30. Using standard alarm app I had a lot of alarms which then I had to delete manually to avoid clutter. Using the standard calendar event notifications were not loud enough so I could forget about them if I didn't have my phone nearby. This app solves this use case. After alarm is fired it is deleted, it doesn't have to be deleted manually as in normal alarm application. READ BEFORE USE! In this app it's only possible to set alarms which don't repeat and only for today or tomorrow! Don't expect this app to be used as a replacement for your standard alarm app or calendar! It's a different type of application! It is not a calendar or standard alarm clock app.

OpeNoise is a real-time noise level meter.FunctionsReal-time A-weighted sound pressure level measurementMinimum and maximum levelThird octave and FFT analysisData saving in text fileCalibrationTerms of UseThis app is not intended for professional use, it does not necessarily guarantee an accurate noise measurement. Since each device has a different response to noise, a comparison with a professional noise level meter in the measurement dynamic range is required. The utilization of the app requires adequate technical knowledge and skill; an extemporary measurement might not be correct.CreditsDevelopers: Arpa Piemonte (Regional Agency for the Protection of the Environment of Piedmont - Italy - www.arpa.piemonte.it).

Open 100x is an Android camera app built to give more phones access to extreme 100x zoom-style shooting, even when the stock camera app does not expose that kind of range. It combines native camera zoom with digital crop to reach up to 100x, and adds controls designed for long-range mobile photography. The app includes stability feedback, histogram tools, grid modes, zoom presets, flashlight support, crop nudging, and local post-processing for extreme zoom captures. Open 100x runs fully on-device.
