Open-Source Android App Offers 24 Free PDF Tools and On-Device Scanner Without Ads

Overview of the Open-Source Project

A newly highlighted open-source project hosted on GitHub provides Android users with a collection of 24 free PDF utilities and a built-in document scanner. Developed using Kotlin and Jetpack Compose, the application emphasizes local processing, running entirely on the user's device without requiring accounts, sign-ups, or internet connectivity for its core functions.

Key Features and Scanner Capabilities

According to the project documentation, the application operates locally with the following features:

• Document Scanner: Features live page-edge detection, support for automatic or manual capture, flash toggling, and front or back camera utilization.
• Capture Modes: Includes specialized modes for documents, books, ID cards, business cards, and whiteboards.
• Editing and Organization: Offers cropping, rotation, filter applications, cleanup brushes, and color pickers. Saved scans can be searched using on-device OCR, which generates an invisible text layer.
• Built-In PDF Viewer: Provides scrolling, zooming, text selection, search highlights, link navigation, page thumbnails, and support for password-protected files.
• File Management: Supports folders, renaming, moving, sharing, and exporting copies as Word or JPEG files.

Privacy and Synchronization

The developer states that the app contains no advertisements, analytics, or trackers. All processing, including OCR and scanning, occurs on the device. An optional two-way synchronization feature allows users to connect the app to their own Google Drive account, restricted specifically to a designated "PDF Tools" folder.

System Requirements and Installation

• Android Version: Requires Android 7.0 or newer. The built-in PDF viewer requires Android 12 with recent system updates.
• Distribution: Available as APK downloads through GitHub releases. The repository notes that side-by-side test installations are supported to prevent overwriting existing data.
• Development Stack: Built with tools including Jetpack Compose, CameraX, OpenCV, and ML Kit. Developers can build the project using JDK 17 and the Android SDK.
