(For other people to see): I tested it on keytrac and typingdna while i was writing the code and it worked, but i haven’t been able to thoroughly test it with another person (it should either detect 0% for each person or ~100% for each person on the same entry). So please report tests to me if anyone tests it.
The best one that doesn’t seem too sketchy is http://jmp.chat/
I’m quite familiar with voipms since I have a reseller account with them for my sms service . They aren’t very privacy friendly, so if you are trying to maintain anonymity there are probably better options. I successfully ported a MySudo number to my voipms.
I’ll point out that MySudo seems to only use Twilio which is a developer oriented voip/sms company. You can directly make account them them and use a web interface but they aren’t very private either and require a non voip number to be confirmed on the account.
If you really want MySudo (note they are proprietary) you could try running it in android-x86 which includes standard google apps I believe. Haven’t tried this
This is cool and I don’t fault anyone for using it but for me personally I don’t trust proprietary games and trust pirated games even less, one of the only times I ever got malware was from a pirated game
