### 3/5 — Uses a lot of battery

*2024-08-10*

The app seems to perform background activities that consume much of my phone’s battery. A Morse code training tool should not do this.

**Developer response:** Thanks for the feedback. I will definitely look into what causes this. 73 Åke SM6Y

### 3/5 — Locks up

*2023-11-27*

Locks up every time when sending international call signs. Sends one then freezes.

**Developer response:** Sorry for the inconvenience. It should be fixed in the current version, though. Hope you enjoy. 73 Åke SM6Y.

### 4/5 — Fantastic trainer!

*2024-03-31*

I use this just to listen and train my ear/brain for CW copy as background sounds. 

Note:
If the dev reads this, would it be possible just to add a few more options? Single letter, single number and mix of a single letter or number? I still find myself struggling with the sounds of some characters, and would be nice just to run through individual characters ad nauseam.
