A good product in need of an update

I have been using this product for several years and always though it was the best thing since sliced bread until I installed it on my iPad Air 2 and iPhone 6 with iOS8+. It works no better with iOS9. It frequently crashes out of the app and I have to open it again. The company has not updated the app in the last five years and apparently doesnt care. The email log feature doesnt work, and the restaurant info omits many national (and international) chains that have entered the market since 2011. I have tried emailing the producer and never receive a response. I keep hoping for an update but am looking for an alternative.
