★★★☆☆Dave, very much, FCD7/7/2019
Crashing
Upgraded rating. Thanks to the developer for his quick response. The app runs fine now. Three stars because the user interface is a bit opaque. [Original review: Bought this yesterday (7/3/19) and installed it on my phone (iPhone XS Max, iOS 12.3.1). It ran fine then, but subsequent attempts to run the app on the following day failed, with the app crashing after displaying the splash screen. Hard iPhone reset failed to resolve the issue.]

STILL NO CONTACT!!!
Has been a decent app until latest update - now it fails to launch! There is no contact info in the developers page to report this or find a solution! *UPDATE* Quick turnaround on bug fix! I enjoy the app and the interface is fairly intuitive. I have multiple chord apps and I find this one to be my go to for chording. Keep up the good work!

Help!
UPDATE: Looks like my issue was user error. Cool app, especially for free! This is a really useful app, and I use it all the time. However, the latest update appears to be non-functional on my iPhone 8+. Specifically, the “Type” menu on the left-most screen has disappeared. This app really is cool, so I hope a fix will be forthcoming. When it works, it’s five stars!
