Doesn’t work without subscription and buying another device

Forces you to buy a subscription and the smart ref to work

The SmartRef works fully without any subscription. Please feel free to reach out to us at support@my-smartref.com so we can clarify any misunderstanding and assist you further. Thank you.

Crippled app to force unnecessary subscription

For a $350-400 tool, I expect this app to be free and self-contained. They could store all your batches in iCloud, but instead are trying to upsell you on their own cloud storage service. Then they split the functionality into three separate apps so they can sell you three subscriptions. I would think twice before buying another Anton Paar product.
