Needs some work

I really love the new web dashboard and I would give that 5 stars if I could. This app however is definitely worse than the legacy version in some ways. I can’t seem to see the current values of sliders anymore so they are effectively useless if you want to use them for any kind of precision.
I’m not that upset about the lack of widgets. I know Blynk is oriented towards businesses not hobbyists, but I think it would serve them well to remember that a lot of hobbyists supported Blynk and there should be a pricing plan for them as well.
I’m not sure if it’s a bug or a feature, but if they fix the issue with sliders not displaying their values then I could definitely give this app 4-5 stars.

Developer Response ,

Thanks for the feedback! Regarding the slider - it works a bit differently from the one in the legacy app and you just need to add Labels in order to show the values. Please give it a try and let us know if you need more guidance on how to do it!

Really disappointing pricing options

I was a huge fan and advocate of Blynk before their new version. Even today it is the only app of its kind, where you can create your own interfaces for microcontrollers on your phone with ease. I would have been happy to pay a couple bucks a month to continue to use it, but these new prices are completely unjustifiable. In addition, the free plan is so absurdly limited that it’s completely useless without upgrading.

Fortunately, it is still possible to use the legacy app, provided that you self-host your own Blynk server. I’d recommend that others try that out, it’s not as daunting as it may sound (check out hortio/docker-blynk on GitHub). You can use *all* of the widgets included with the old app, and also give yourself as many points as you need, so no in-app purchases.

To the Blynk team: reconsider this change, and think about what made the original such a success.
