TFBox

TFBox brings practical, device-based utilities together in one focused workspace. Check a level, explore distance and environmental readings, review sound levels, scan codes, extract text from an image, or create a QR code without switching between separate apps. Measurement tools include a level, distance reference, altitude, speed, and barometric pressure views. Audio tools offer voice effects and a sound-level reference. Recognition and creation tools support QR and barcode scanning, image text extraction, and QR code generation. Recent results can be kept in your on-device history for convenient review. Some features require compatible hardware and permissions. Readings are intended for everyday reference only and can vary with the device, environment, and use. They are not a substitute for calibrated equipment or for safety, navigation, medical, legal, or other professional decisions.
