I use the Muse EEG band [1] but with the Mind Monitor third party app and tools [2]. This is another case of an official app being subpar to the hardware device.
Did you have any specific gripes with the Mind Monitor app? The visualizations seem nice, but it would be interesting to see a feature that allows synchronization with other data sources. (e.g. connecting a keyboard to capture both neural activity and keystrokes simultaneously) That said, this might not be worth the effort. For me, obtaining high-quality data was a challenge, which I suspect is a common limitation of non-invasive electrodes.
You can export your data and work with it. Also, there are some online tools and docs [1][2]. Also, there are open source libs such as [3]. My only "gripe" is knowing enough about EEG.
