Comments and feedback

We take user support very seriously. Our belief is simple, treat your users the way you would like to be treated yourself.

We do however have very strong opinions on what features make it to our products. Talk to us and we’ll be happy to explain our reasons, our thought process when coming up with what an app needs to do. That said, if you have an excellent idea or a feature that you feel we missed out drop us an email. We love helping our users.

We have extremely detailed help documents available for all our apps below. For absolutely anything, problems with an app, things you don’t like, app suggestions. Seriously, just try us support@parabolicriver.com.
