I needed a simple app to measure vibrations on my desk because it was wobbling a lot. As soon as I opened the app for the first time I saw the oscilloscope running. No ads, no account signup, just a super minimal interface that shows me exactly what I need. I would happily pay $ to support the dev team based on my experience alone. The visuals are also beautiful, I spent way more time than necessary just shaking my phone to see the geyser and metronome move. I almost gave four stars due to one annoying quirk: whenever the device is rotated I lose my graph. If I’m in the oscilloscope and rotate to landscape, I have to select my chart type again. It’s also weird to me that the bubble level is hidden in the settings and not a top level view option. **Developer response:** Thank you for sharing your experience with our app! We're happy to hear that you found it useful and liked the design. We apologize for the issue with the graph disappearing when you rotate your device. We will work on fixing this in future updates. We also appreciate your suggestion about making the bubble level more visible. We really appreciate your support and feedback. Your input helps us make the app better. Thank you again! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
