The app has been very helpful in keeping track of our appointment schedule with many different doctors across multiple facilities over several states! It's easy to use as well - no need for training or any special software required from other companies that I've tried before it (such as Evernote). There are some minor bugs here & there but they're easily fixed by contacting support staff via email which works perfectly fine since we have an account manager who takes care of customer service issues right away so far nothing major at all. Tracking my doctor visits using this tool makes scheduling them much easier than calling each office individually every time i want something changed / added etc.
