Old review below, here is an update:
Update, finally got an update and maybe there is hope, please keep them coming.
As I said previously this is one of the easiest apps to use that I have found, but there are some slightly irritating bugs such as getting kicked out of a recipe mid edit.
Bottom line, great app, but buggy, if it continues to be updated there may be hope.
If it helps, this is still my default app for recipe formulation

Dead App! Do not waste your money!!!
l had IBM1 and loved it, frequent updates, and fixes as needed. Could not wait for IBM2, and updated as soon as the new version came out, at significant expense. New version had cool features, but buggy, as any new app will be. Instead of being refined overtime, the product is stagnant. Updates and fixes are few if any...
Truly a pity, this app had potential to be the definitive app for brewing, it was easy to use, and intuitive, but because of neglect it is a waste of money. I say this because after using may other apps, this is the one I found easiest to use. Very disappointed at the result of this franchise. Do not waste your money!
