Excellent cookbook; outdated UI – How to Cook Everything Review

Good job with updating to iOS 11 but it definitely needs a full UI update. Love the book. The app adds convenience. But please please please actually update the app UI. This would be a 5 star review for content and I will update accordingly when they do. Edit: Thanks for the clarification about 64bit, for that I'll add a star. I look forward to the update.
