Well worth it
Initially I was hesitant to buy the app because of the cost but after making the plunge it was well worth the money. For a home roaster this is your right hand man, logging roasts, a wealth of detailed inputs, logging raw beans, cupping scores, and compatibility with thermometers. Theres so much this app provides that replaces a excel sheets and notebooks. If you check the company forum, their customer service (the creator of the app) communicates with you directly and helps you with whatever question you have. Overall, you wont be disappointed if youre tired of tracking your roasts manually!
