I came across this awesome kickstarter. The SmartScope is a 100M/S (45Mhz) oscilloscope that is compatible with PC/MAC/Android/IOS. Although it looks like you need to jailbreak for IOS. It also packs a 100M/S digital logic analyzer and an arbitrary wave form generator! The UI looks pretty polished as well. I hope that the logic analyzer would decode UART/SPI/IIC/Etc. There are still some slots open for $179, a great price for a 3-in-1 tool.
Check it out!
