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.

Our free Vernier Instrumental Analysis™ app makes it easy to incorporate instrumentation into your chemistry curriculum. The user-friendly interface walks students through the data-collection process and includes instrument-specific analysis features. Collect, analyze, and share data from our Mini GC™, Mini GC Plus, Go Direct® Mini GC, Go Direct Polarimeter, and Go Direct Cyclic Voltammetry System with this free app. Students can collect a gas chromatogram from the Vernier Mini GC, Mini GC Plus, and Go Direct Mini GC. They can also determine peak area and integrate peaks. Using Go Direct Polarimeter, students can collect polarimetry scans and optical rotation data for individual samples, as well as over time. The mutarotation kinetics of sucrose has never been easier to observe. If students have the Go Direct Cyclic Voltammetry System connected, they can easily collect voltammograms to analyze current peaks and determine standard potentials of electrochemical reactions.
