App Crashes constantly and Customer Support Non-existant.

I have an iMac 21.5 inch late 2013 model using the latest version of EL Capitan. When I first purchased the Sweeper App it appeared to be working. However, early on it started to crash every time I attempted to perform a function in the App. While the App worked on my MacBook Pro Retina 13” (late 2015 model) it has failed to work on the iMac. I sent an e-mail with the error message attached, regarding the crashing problem to the developer as provided for in the App, but have not received either an acknowledgment or advice on how to fix the problem. I would not recommend this App to anyone who owns an Apple computer. The App’s customer service is basically non-responsive. Apple should remove this App from the Apple Store until they are assured that the App developer actually provides customer support as promised and has resolved the crashing problem that exists in the App. Don’t buy this App. You might be wasting your money.
