Many unnecessary differences between website and iOS

There are various differences between the website and iOS. This should be consistent.

- tracks in my library on iOS show the file extension (mp3/mp4) whereas they don't show on the website because I edited the names. The website is correct, the iOS app is not.

- the website shows the key, BPM and chord summary when I have opened a song. The iOS app does not! Especially the missing BPM is quite annoying.

- on the iOS app I can reduce the speed only by 25% steps (75% and 50%). The website lets me reduce in 10% steps (90%, 80%, 70%, 60%, 50%). Those 10% steps should be available in the iOS app as well.

- the iOS app regularly reports connection issues. My internet and Wifi is fine - Chordify is the only app complaining about it. Clicking on the menu, switching pages a couple of times usually solves the problem.
