Portable and precise but limited
Works well for what I use it for. Debugging small voltage electronics (arduino/pi/etc..) Very portable and useful in a pinch. The Oscium team is easily communicated with and helpful, so I count that as a plus but there are couple cons to add. You can't reanalyze the data in the app later and scroll to the time you want to look at. You also can't export it and open in another program in your computer. There's another guy who made a filter to parse the exported data and open it in salae's software I think but it was only for a certain setup and didn't work for me. So you can use it for real time analysis but not for later on to check the results. ***Careful the voltage is limited to -2 to 7v and there's no over voltage protection. So that could easily be a $200 dollar mistake. I always measure the voltage first to make sure and am mindful of spikes. ***update: 3/24/19 - app still works well and even though I have the adapter from Apple (the old style to lightning) it works well. Bought in 2014 and very careful to measure under the voltage limit prior to connecting. Glad the manufacturer is still proving app support 5 years later. Keep us productive!
