Ratings and reviews

Pretty disappointed. Legacy Blynk was great - had a ton of widgets, and was intuitive to use. Now even with payment, they lack many widgets from the old version. I used and paid for old Blynk for its ease of use & feature set, but now I'm better off putting in the time to develop full custom solutions since they've removed everything that made it good & easy to use.

The Blynk 2.0 system takes some time to migrate from the Blynk Legacy system. Once I transfered my project and got more familiar with the Blynk Console, I actually like the new system. In particular the WiFi provisioning system is a major upgrade. My disappointment lies in the new pricing system. The legacy system was perfect for DIYers, like myself, for small home projects where you are only using a couple of devices. Additional widgets could be purchased with energy, which I invested a fair amount in. In Blynk 2.0 the widgets are extremely limited and my previous projects and layouts will not work without upgrading to one of the pricing plans. I am not trying to commercialize my projects, so joining a subscription doesn't make sense. I recognize the hard work that the Blynk Developers have put into this ecosystem and would be happy to "pay my dues" for that work. However, I would like to see something where I could purchase all the widgets perpetually for a one time fee.

When I had the previous version of Blynk I spent a few dollars on energy which is now worthless. I think at least they could make the amounts spent on energy available in subscription discounts. Even so, I won't pay as it's a non-commercial learning project. The widgets available on the free plan are VERY limited. It doesn't make sense to me. I'm going to look for another more complete platform that serves me free of charge for small projects.
