The Digital Audio Capture (DAC) app is a free app developed by College Board and ETS to use for recording students’ audio responses for the AP Music Theory Exam and AP French, German, Italian, and Spanish Language and Culture Exams. This app has been developed to simplify the recording process for students and proctors, utilizing current technology that is intuitive to most students. It streamlines post-exam tasks for school staff by directly uploading student audio files after recording. School staff will follow the instructions in the 2025-26 AP Exam Instructions book to administer an exam using the DAC app. NOTE: The DAC app is limited for use on school-owned and -controlled iPad tablets (iOS 15.0 and above). Schools must update to the 2026 version of the DAC app; previous versions of the app will not work in 2026.

Verdict
The clearest difference is rating: goREACT at 2.2 against DAC App's 1.8. goREACT also leads on update cadence (every 4 months vs every 12 months) and ratings volume (99 vs 16). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
goREACT holds the better App Store score, 2.2 against 1.8. That said, the two scores are not equally well evidenced: goREACT has 99 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 18% of goREACT's written reviews are positive against 20% of DAC App's, so the app with the better star average is not the one people write more warmly about.
goREACT ships an update every 4 months, DAC App every 12 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
