Koch Morse Trainer Pro Customer Insights

1. Beside the obvious, you can listen to rss newsfeeds and train in all speeds and modes all day long...This is an excellent learning aid with the ability to adjust the speed and timing of characters and word spacing is great.

2. The statistics and the ability to practice with RSS feeds make this the perfect app for me.App is great, however it stays in idle mode after closing and drains my battery.

3. My only issue is that the RSS feed output starts jumping from the top of the screen down to the bottom, then back up again between each word, once the text reaches the bottom of the window and has to start scrolling the visible window.

4. Within a very short space of time of installing KMT Pro i found i was "seeing" letters in my head from the sound without trying to decode the dots and dashes.

5. Will rate higher once this is fixed.Excellent so far! Ive been looking for a way to learn morse for fifty years.

6. It takes a lot of practice to learn the code, but this seeems to help.It is an excellent app but only 30 minutes each time is a limitation.

7. The screen jumping around when text hits the bottom is not good, maybe it can be fixed.

8. A way to go yet but very impressed so far.Great app for learning cw as well as for increasing speed but keeps running after closing the app.

9. Have not found a way to get the app out of idle mode so it closes and does not drain my battery.

10. Otherwise, this is a really good tutor.works real well on my samsung tablet with a pair of headphones.

11. This is stomach churning if you're trying to read while listening to the code.
