It is not very useful without your own local server This support has been removed Blynk used to be the easiest way to prototype, but they have sold out. I backed you guys on Kickstarter, you had a brilliant idea, but the new version has really missed the mark. I know I can still use the old version, but the UI is so broken and you can't make the widgets small enough. My recommendation: keep everything in the front end the same, but add Bluetooth and local-server support!

Legacy version was retired and if you had credits they're gone. New version is incredibly painful to use - to the point where I'd rather make/look for any alternative. No local server, which makes half my projects useless. Just horrendous. I'd pay for use of the old app, even with no local server. It's a perfect example of how to ruin something that worked well and everyone loved. Developers have shot themselves in their own feet, and don't know they're bleeding with this one.

You can still use the legacy version if you like it more, especially if you have the Local Server. Blynk 2.0 doesn't affect you in any way.

I liked the legacy version where almost everything was simple and clear and you can do ALOT for FREE. I mean I get it, going enterprise is something everybody wants to do, but now with this newer version, not only it is complicated, you can do only few things with the free tier, alot of things are only limited to the PRO version subscribers. Subscription prices are waay high for a hobbyist. Will still use it though, but not with a big smile on.
