I have created one, called Connective:

PlayStore: https://play.google.com/store/apps/details?id=com.connectify... AppStore: https://apps.apple.com/us/app/connectiveapp/id6624294792

Maybe is not the best, and I'm still working to improve it and add new functionalities. The major problem now is we don't have much users, so there is few content.

Feel free to use it and if you have any questions, please let me know
