A developer frustrated with unlocking his phone to take notes has launched Joonote, a lock screen note-taking app for Android. The native Kotlin app lets users view, edit, and create notes directly from their lock screen and notification panel without opening the main app. The developer built it over a year using AI assistance through Gemini's chat interface.

The app includes features like check lists, reminders, speech-to-text, and custom color labels. Users can also set notes to private, search through full-text, and organize with custom labels. A home screen widget provides quick access, while offline functionality ensures notes are always available. The app backs up to Google Drive and works without an internet connection.

Priced at $9.99 for a lifetime Pro upgrade after a 30-day free trial, Joonote addresses a common mobile frustration. The developer, primarily a web developer, learned Android development and Kotlin syntax through the process. Early user feedback praises its simplicity and speed compared to traditional note apps, with one user noting it eliminates the multiple steps typically required to access notes on Android devices.
