Comments on Morse Expert for Android

★★★★★ Lucas Burlingham · Apr 23, 2025

By far the best CW decoder. Works great even with a high noise floor.

★★★★★ Brian Donlin · May 11, 2026

Works very well in decoding from video and from radio. A definite need for those with "CW dyslexia" where there is a gap between hearing and head decoding, making it very hard to QSO without having to slow down a lot to listen.

★★★★★ green top · Oct 10, 2025

Accurate. Designed well by some who knows what works for a CWer who can't copy but 15 wpm but likes to QSO with hams capable of higher wpm.

★★★★★ Airton Granero · May 20, 2023

Cool...it decoded the Morse code on the beggining of a RKO Radio Picture, and the Morse code on Radioactivity by Devo.

★☆☆☆☆ Muckel Stein · May 23, 2023

Utterly useless. It has completely rubbish audio detection/identification, so every single noise it picks up will be interpreted as morse code. So unless you're using it with a completely clean recording in a sound-proofed room, it simply WILL NOT WORK.

★☆☆☆☆ Stephen Sutker · Dec 6, 2025

This may be a great app, but it only lasted about 3 min on my phone. I couldn't make it past the ads to even evualate their product. NO, THANKS.

★★☆☆☆ Bj L · Jul 6, 2025

Great concept however, it only read CQ, and sometimes it seemed to read a call sign.

★☆☆☆☆ Charles Maslin · Jun 3, 2024

Adds don't go away after upgrade to premium unless you have Google open. I don't want adds, and I don't want to have to leave google play open. Fix or refund please
