Currently, we have a device prototype for the deaf and mute, and a mobile application with ready-made API interfaces. We want to create a dedicated web application to receive and process the data sent from the phone.
I personally know of:
- Transition Technology - https://ttpsc.com - huge organization, I don't know if they will want to work with someone small;
- Inwedo - https://inwedo.com/ - this company is closest to my heart;
- Liki Mobile - https://likims.com/pl - I thought of them because you mentioned a mobile app;
- Fabrity - https://fabrity.com/ - I used to work with them, but it's hard for me to say anything concrete after so many years;
If you have any questions, let me know.
