Pro version is amazing

I recently purchased the pro version. Had some difficulty with the update and accessing the pro version material at first. I emailed customer support and Matthew responded swiftly with the appropriate solution to the problem I was having. I have found the app to be very helpful in the clinical setting as a student. I have been very happy with my purchase thus far.

Incredible anesthesia reference

Matthew and his team have created an thorough and comprehensive app to efficiently look up need-to-know information on various procedures, conditions, and medications. I had a brief technical difficulty with the app and Matthew was very quick to respond with assistance. Will continue to subscribe!

Why am I being asked to repurchase Pro version?!

I recently purchased the pro version and everything was working fine until the past week or so. Any time I try to access app the screen would go all white as if trying to load. I deleted app but chose to keep my membership and redownloaded. I am now being asked to purchase pro version AGAIN. I do not have money to keep paying for an app I’ve already purchased. There isn’t any way - that I could see to contact the owner/developer of app to report this discrepancy, so here I am with this review!
