The "Alphabet Tree" is centered VERTICALLY now, too.
For sorting and quickly finding alphabetical data, software programs use a so-called "binary tree" method. I have modified this method somewhat, and with this app you can play around with it.
The app is using the 26 characters of the English alphabet plus 3 German-only characters (ä, ö und ü).
The app is self-explanatory. This means that in any situation only those activities can be started which make sense at that moment.
Besides this, the app can be played offline (airplane mode). After being downloaded, no wi-fi or mobile connection is needed.
One more thing: for entering characters, I am using the old method which was used before touchscreens came up. A that time, for the character "f", for example, one had to type (now: touch) three times. - I modified this method, too. You will notice it.
Now have fun playing around with the characters!
