Unusable. Update: disable Face ID and PIN screen is usable. ### 5/5 — Great lightning Chatting and tipping app *2022-08-09, version 1.0.8* It makes you feel very comfortable if you run a lightning node knowing your data is in full control. ### 4/5 — Unable to log in… *2021-09-08, version 1.0.8* Want to be a big supporter of Sphinx Chat, but I’m unable to log-in on my latest version/up-to-date-OS iPad. The PIN# screen comes up, but the num-pad doesn’t work. Might be something I can fix in the account settings, but since I can’t log-in I can’t investigate. Right now Sphinx Chat is a brick for me. ### 4/5 — The FUTURE! *2021-07-09, version 1.0.8* This is an amazing app tackling a huge problem, decentralized communication & finance. Obviously there are some bugs but it’s absolutely worth the time to work through them. Spin up your node and launch SPHINX ASAP! Developer team, please let us know how we can help you take this to the next level! ### 1/5 — CAJ *2021-07-08, version 1.0.8* Really buggy app..continue to try to re-install, but stuck on sign in screen ### 1/5 — Would love to use it *2021-05-20, version 1.0.8* Broken app, won’t sync to my node, won’t show chats… UI isn’t user friendly… please get this up and working. ### 4/5 — Lots of Promise *2021-04-19, version 1.0.7* The app desperately needs to be able to control app badging on a per-channel basis, and emoji reactions and other polish to make it competitive, but its extremely exciting and I support them 100% ### 2/5 — Super buggy *2021-04-13, version 1.0.6* I wouldn’t run the relay on my node. With how many bugs there are, I don’t trust this thing with my sats. ### 5/5 — Amazing proof of concept *2021-04-11, version 1.0.6* Private, trustless, end to end encrypted communication with no third party sticking their nose into everything. This will change the world. ### 5/5 — Bitcoin! *2021-04-05, version 1.0.6* I’m here because of Preston Pysh ## Frequently asked questions about Sphinx Chat ### What is Sphinx Chat's age rating?
