Qualaroo

The best thing about Qualaroo is that it only takes a couple of minutes to set up, and you can start collecting feedback instantly. You can also deploy it on multiple channels, including websites, SMS, mobile apps, SaaS products, and more. Qualaroo mobile web also supports multiple devices, which makes the displayed surveys responsive on every device.

One thing that Qualaroo can do is tweak the UI and survey themes a little. Apart from that, everything was great

I would say my experience with Qualaroo has been absolutely pleasant. It had proven to be really easy to control and command with just a couple of minor hiccups.
