Some researchers and authors were asking me, whether it is possible to get a Musnad-Keyboard which can be used instead of the soft keyboard of the phone to write short assays or similar.

Of course it is possibile to create a kind of a universal mixed keyboard. But in which of the five different Apps this should be implemented? Some of these app has reached a maximum limit of functionalities. The only possible way left is to create a new app.

But lets first understand the requirements of the users...
A user writing a text about an old inscription or for a book about a topic concerning Musnad may need at least two of these things:
1. Musnad text or words (e.g. ???? it is form right to left; means brotherhood; alliance) )
2. Equivalent in Arabic (ءخون)
3. Standardized Latin Chars (ʾḫwn)
4. Text to explain etc. in e.g. English, German, Arabic, Chinese etc.
5. The user may want to use 2. or 3. above to get the word in Musnad letters, but she/he is not really skilled in using the Musnad alphabet.
6. While writing one may wirite a Musnad text using Lt or Ar letters. OK, not problem: just selct the text, switch to Musnad Keyboard and use the key to convert ♻.

The user may want to save/ restore the text into/from the device. The retrieved text may also be inserted in a new text.

It is here not about having a perfect keyboard, but to easily save a lot of time doing the job. The user may also wants to share the text with someone else via whatever communication channel.
