Blynk IoT User Reviews

Top reviews

Definitely the best IoT app builder out there!

Blynk continues raising the bar for all IoT platforms for many years. There is just nothing else so easy, beautiful, and intuitive. Built many personal and commercial projects - always a success! Thank you, guys!

Response from developer

Pablo, thank you for the amazing feedback🙏 Wish you success in future projects!

Best IoT Solution

Wether its a simple or complex project you need to get done, this app solves majority of cases with a very simple integration and user interface. Their documentation is good too which is a plus. I really can't recommend Blynk enough.

Response from developer

Hi Jorge, thank you so much for the review!

Start guide is not clear to follow

Can you have a complete hello world type tutorial on both or three sides hardware parts, host and phone

Response from developer

Hi Jz, thanks for your feedback. We have just launched a new feature - pre-built templates with firmware and a step-by-step tutorial. You can try connecting your device with this blueprint if you are using an ESP32 board, or check other blueprints in the library https://blynk.cloud/dashboard/blueprints/Library/TMPL4BlJLIkw7

Easy to get up and going.

Once I set up my account, without any issues and was able to test in the preview mode. I purchased the service the same day. I started with my PI and was able to have some circuits up and running and communicating the same day. The documentation and number of examples available made perfect starting point for several projects on my list. Thank you for such a stable and easy to use product.

Ben, glad to hear that documentation was helpful for you. Thanks a lot for your feedback!

Apple Watch app?

Can’t find the Apple Watch app

Great App

I just recently installed blynk and still learning alot about the app but this is the best app to learn and monitor different sensors on

Oh dear. Blynk has sold out. RIP beloved projects.

Update: Despite my many and bitter. misgivings (detailed below) I decided to migrate our project to the new Blynk. What a pain! Very convoluted this obviously now aimed at commercial IOT deployment where someone has many hours to create ‘templates’ and virtual ‘devices’ to communicate to your real devices. Layers of work. Sadly I found many Arduino sketch errors in the documentation. Not good. The final kick in the pants is that to get a graph of any output you need to subscribe. The free option has very limited ‘widgets’ with which to display your data. Subscription is expensive either at £5.99 a month which unlock a few more options or for more options a HUGE £41.99 a month; Beyond many hobby users budget. Which options you get for the lower fee is unclear until you actually pay. Nasty.

So let’s see is it:

Easy to use? No
Cheap or good value? No
Clear to see what you get? No
Well documented? No

Does it work after you’ve put in the hard work and paid ? Yes

Is our old family Blynk project alive again? Yes

In the end it’s a sell-out and a cash-in. It works but I resent the exploitation. As we say here ‘it’s having your eyes out’.

Original review follows:

I loved the old Blynk: Easy to use and code with my Arduino and ESP devices. Really easy to connect and display remote data generated by these cheap but amazing things. I used it to teach my kids and others how to get data and send data to home made IoT devices. Great. The essence of making. However : new Blynk. Ugh! Geared to pre-made commercial branded hardware. What a nightmare. It’s obviously chasing the money in the enterprise market. Now they are killing support for the old Blynk. Well, thanks. This is the kind of vile sell out that will eventually kill open source. Don’t invest too much time in this they’ll sell out again when a larger corporation buys them and they’ll shut down your new projects too.

Update: Well it happened. A day later than they said, a day later of hoping that they had changed their minds; an 11th hour death row pardon perhaps. But sadly it did and it was a difficult moment: It always is when something you brought into the world dies. The legacy server was pulled and my little ESP project that I first breathed life into finally transmitted its last bit of data. He was the result of an idea, some nice code and some snazzy waterproof hardware and several years of refinement and nurture of software and hardware iterations. Now dead. Cut adrift like a space walker with a severed umbilical. Data spraying out into space like frozen oxygen crystals glinting in the moonlight. RIP little buddy. Sleep well, the company that allowed us to talk and share the life’s breath of data simply doesn’t want us any more. I’m sorry. I am weak and vulnerable; I could learn to recode you with they new IDE but can I trust them not to pull the plug again? No. And no:; I can’t go through this again. Now the kids have plans to bury you in the garden next to the cat. I have some explaining to do.

$58.99/month to prototype single widget

Blynk’s website advertises free to test and prototype, yet Single video stream widget is $58.99/month! “month” not year.

Unusable

You made this new version unusable. Why not leave some of the legacy stuff in there. And your write a review also does not work. I can’t see what I type.

Best Arduino platform for building mobile IoT apps - for hobbies TC’s & pros

I’m a semi-hard-core hobbiest, have used Blynk for years, had no problem moving to the new and much richer platform a few years ago, and love the better approach of today’s Blynk. I am running a number of control and monitoring apps in my house on both Android and iOS.

No, Blynk is not free. I do find their pricing fair, especially considering how much they continue to pour into the Blynk mobile user interface and the back-end data management. Data flows are managed centrally through a browser-based dashboard that makes data and device management and coordination simple and clear.

Using Blynk with ESP8266s and ESP32s on the Arduino IDE has been a joy. My many apps are stable and available to me globally, which is great because I travel. It’s not a closed system as it’s easy to program Blynk apps to communicate with external systems. I use IFTTT and Google Assistant and run with Telnet, for example.

Blynk documentation is constantly improving and the community that supports, comments, and asks questions about Blynk remains active. You can find out pretty much anything about using Blynk one way or another. I now have a number of templates for rapidly spinning up new Blynk apps for monitoring something or controlling something else, all with excellent mobile phone user interfaces. Blynk supports OTA and many features for professionals, as well.

For me, as an earnest hobbiest, I have not yet seen anything that makes me even think about moving from Blynk. I continue to develop on Blynk and hope to continue.
