Review summary

Overall, most reviews praise Blynk IoT as a useful, beginner-friendly tool for IoT projects, especially for students and educators, with a free option. Many users find it easy to use and valuable for automation. However, recurring issues around reliability—freezes, reconnect errors, and login/authentication problems—along with UI/UX criticisms dampen the experience. The sentiment is mixed: strong educational value and usefulness amid stability concerns.

2026-07-02	Da*****	Every single time I close and reopen the app, I am completely logged out and have to sign in again. (I have given background activity access to this app). Additionally, the initial loading screen takes an unusually long time to load, as if it is struggling to authenticate my account or fetch the login screen. Please fix this session persistence issue. Update: I have cleared the cache and data. now it is working fine. Thanks
