Developer ignores the app
I like this app, but when I clicked on the purchase button to unlock all the features, it didn’t work. The sound cues and reminders were unlocked, but no additional levels were unlocked. I wrote to the developer via the “Contact Us” link, but my message was returned as undeliverable. That being said, the $4.99 purchase never went through either - it’s listed as “pending.” My conclusion is that the developer isn’t interested in monitoring activity for the app, so it’s basically impossible to go past level 10 (100 levels are promised when purchased). Too bad, because I liked it enough to purchase. I cannot recommend this app due to the developer’s lack of involvement.
