This is completely voluntary.
I am looking for testers who would like to test my upcoming B4A app, RoboTexter.
The app uses a bot to reply to SMS messages that are solicitation or spam. If you are getting unwanted SMS text messages, you can add that phone number to the blacklist so the bot will always respond to that person. Alternatively you can add all your contacts to the whitelist so the bot never texts a person from that list.
Right now it's just a very basic early version. If successful, I plan to add many more features to the app.
