As I understood, it will be hard for vendors to understand and install the MainSale app and they will need help with it, correct?

Our app is very user-friendly. You can download it now in android and IOS versions. Please let us know what you think. Thank you

Please, give the link here. I can't find your app at Play Market. Thank you

Once your in google playstore, just type Mainsale app in the search box or try this link: https://play.google.com/store/apps/details?id=com.rockstable&hl=en

Your app doesn't work on both of my phones. It says "The application is not compatible with any of your devices."

Where did you download it? what device are you using? Android? Iphone?

If you have such mistake, you can't download it. Android. Not comatible. And my phone is not so old.
