I have been teaching piano and actively working online since 2020. I've tried all existing platforms. I have been using this app since July 2023, and currently, I have completely switched to this application. What I like: 1. **Sound synchronization:** In my opinion, this is the biggest advantage of the application. No other platform allows working with a backing track or metronome synchronously. Everywhere, there is a delay of several seconds. 2. **Collaborative work on sheet music:** There is the ability to enter text, draw, and make notes directly on the sheet. The student has their cursor, allowing them to demonstrate something. Essentially, it's like working in a "live" format. 3. **Multiple camera connections:** Both I and the student can connect multiple cameras. Consequently, I can show everything in detail, and likewise, see in detail what the student is doing. As for the downsides, various bugs occasionally pop up. However, the application team promptly responds to all inquiries.
