If you are in the veterinary field, get this app

Makes drug calculations so much easier; this is way faster than looking everything up in a formulary. There are also many other features such as toxic dose calculators for chocolate and rodenticides, glucose monitoring features, fluid rate calculators, and a feature to help grade kidney disease amongst other things. The only downside is that it’s geared towards cats and dogs and no other species. For other species you can still use the app but you have to enter drugs and recommended dosages manually.

Very helpful app with much potential

I use this app on a daily basis to calculate dosages of various medications, particularly when writing anesthetic protocols. The overall design of the app is quite good, proving that the designers are quite skillful and knowledgeable. The app is not completely flawless yet, and a new drugs/changes in drug concentrations are not always saved as they should. When the order of drugs is changed the app doesn’t seem to always save it either.
One suggestion I would make would be to add the ability to highlight a drug (line item) by clicking on it. This would make it a lot easier to pick dosages out of a large list and avoid making mistakes due to the proximity between numbers. Overall a great app though, well worth the cost. My compliments to the makers!

Developer Response ,

As a veterinarian and the sole developer of Vetcalculators, I really appreciate your suggestions and comments. Highlighting is something I can add to the next update.

Very responsive support!

Recently I had 2 issues which affected my ability to use this app-both issues were resolved ASAP. I discovered the customer support email for the 2nd issue, and within the hour I had already received a reply back! A temporary fix was discovered to get the app working again within another hour. And they fixed the main error by the next day. Overall, very pleased!!! Well worth the $$

Developer Response ,

There was a bug in the last version that has been fixed in version 2.9.98. Unfortunately, all updates have to be approved by Apple before they are available to users and it took 24 hours. Hope you can update the App and reconsider your review at some point.
