The CHECK-AT app is your digital companion for an easy verification of the new Austrian passport and ID card. With the app, check the QR code and other security features on the new passport generation easily and securely. Simple verification - without any need for technical expertise: In addition to the convenient QR code check, the CHECK-AT app guides you step by step through verifying individual security features on the new Austrian passport and ID card. Using examples, the CHECK-AT app allows you to thoroughly examine the digital and physical security features of the new passport generation and ID card – even without any special expertise. Local verification without retrieving personal data from the internet: During the QR code check, the information contained in the QR code is only displayed on the verifying device. The relevant information is directly included in the QR code and is not retrieved from a database. The app connects to the internet during the startup process to check the availability of new certificates necessary for the correct and secure verification of the QR code. If new certificates are available, the app automatically downloads them to the device in use. Furthermore, the app does not connect to the internet at any other time. No personal data is retrieved from the internet or uploaded to the internet.

It does not do live transcription while recording. It does not currently have speaker detection. Try the trial first. See website. Note: Sharing from Voice Memos on iOS 26 does not work because of a iOS 26 bug outside of my control.

I don't plan to support any editing. Export the transcription and edit it in a proper text editor. ‣ Why is the app so large? The app delivers the highest quality transcription on the market for 100 different languages. Rather than asking why it's so large, the real question is how is it so small. ‣ Why is the transcription so slow? The app favors accuracy over speed. However, performance is expected to improve in the coming months. ‣ Why must I keep the iOS app open while it transcribes? iOS apps are fundamentally restricted from operating in the background for extended periods. ‣ Can I delete some of the languages to save space? This is unfortunately not possible. The model has all the languages stored together in a way that makes it impossible to remove just some languages. More FAQs on the website. ■ Technical details The app uses the Whisper medium or small model on iOS depending on available memory and the large v3 model on macOS. ■ Privacy The transcription is done locally on your device. Nothing leaves your device. ■ Support You can contact me through the feedback button in the app.
