Currently there is no plan to shut down Blynk legacy platform server. So old apps will continue working, but will no longer be developed or supported. We recommend making the transition to the new iOS & Android apps ASAP to not just take advantage of the new and ever-improving functionality, but also to ensure stable performance of your projects.
Blynk legacy platform users will get 5 additional free devices if they register and activate their first device before July 25.
Users who purchased Energy in the old app will get 5 free devices and 50% off any annual plan if they register by July 25.
