I am appalled that this company created a non-subscription app which you could purchase, and then decide to do an update, forcing you into an unwanted subscription. If they wanted to do a subscription-based app, they should've created a totally different app and respected the agreement between their previous customers, who had already purchased their app. Which, I might add, no longer works unless you buy the subscription. There are other options out there, such as Pennyweight, that are great apps. Don't waste your money or time here unless you want to be suckered into an agreement that could very well change to benefit them, not you, the buyer.
