Review summary

Reviews are mixed but generally positive: users praise the app’s controls, waveform capture, and calculation accuracy, as well as overall quality and hardware support. Repeated concerns focus on input connectivity failures, reliability on certain devices or after updates, and inaccuracies in waveform representation (square waves and sine/triangle shapes). Some users also request clearer setup instructions. Overall sentiment leans positive, but reliability and accuracy issues limit universal adoption.

Pros

Good controls and intuitive UI
Captures waveforms and frequencies effectively
Frequency and time calculations appear accurate
High-quality design and performance, including with the hardware module
Overall positive reception across reviews (Excellent/Very good/Nice/So good)

Cons

Input/mic connection issues with TRRS/mic input
App instability and compatibility problems on some devices and after updates
Waveform accuracy issues, including incorrect square-wave display and inconsistent waveform shapes
Onboarding/usage guidance could be clearer

2021-03-17	Rk*****	Not giving a perfect square wave. Frequency and time calculation is accurate. When I give 25 Hz 20%duty cycle it does not show on time at 20% instead it shows 50% square wave with clippings. Please give the correct probe ckt diagram for mic input. Thanks for a good scope app in playstore. RK seth.
