My advice is that ANOVA needs to stop wasting their money and valuable software resources on the app. The process that will lead to efficiently satisfying customers is to designate a product manager and have this person write up the proposed specification for the app. This specification should then be validated with the customers. Once this specification is complete I am sure the software engineers will do a superb job at implementing it.
The current app is useless to me. It is a waist of time for me to even describe the problems until you have put some process in place to meet customers needs.
