What is the difference between a Premium Subscription and a Free Subscription?

While the Free Subscription allows users to control all necessary kiln functions from the TAP Kiln Control Mobile app, the Premium Plan (available from $4.99/Month or $49.99/Year) unlocks additional functionality and quality of life features.  

For the original TAP II Pro Controller and the original TAP, the Free Subscription includes full access to every feature except for Remote Start, which is only available with the Premium Subscription.  

For the TAP II Controller, Real-Time Firing Adjustments, Remote Start, Schedule Management, and Log Export are only available with the Premium Subscription.
