Just tried to return to it … but it seems like the log in server is out… stupidly signed out and now I can’t log back in. :/ ### 1/5 — Setup Failed *2025-04-16, version 1.2.4* I have a brand new Foci and every time I try to sign up in the app, it says “Sign up failed. Please check your network settings and try again.” It does this on every single phone I’ve tried. I didn’t spend $100 for something I can’t use. Get back to me with fix or I reserve the right to file a court action against you in my jurisdiction. ### 1/5 — Unable to log into account *2025-04-08, version 1.2.4* Cannot access account or update device. ### 1/5 — Servers offline *2025-01-01, version 1.2.4* After using app for a few years, suddenly unable to log in. All attempts at contacting customer service fail. Appears out of business. ### 1/5 — Device synching is a big problem *2024-10-07, version 1.2.4* Even though it works fine once properly linked and synch but it goes disconnected or ran out of charge for few weeks there’s no way to get it back to normal. Then it becomes a garbage. No physical buttons ### 5/5 — Live activities *2023-12-19, version 1.2.4* Live activities would be really cool ### 5/5 — Great *2023-11-11* I love foci it’s really an amazing device. ## Frequently asked questions about FOCI ### What does the FOCI app do?
