I tried to focus on a problem which i faced using other tools in the past - Placing a widget/ Feedback button somewhere in the App and hoping users would go in and share feedback/complaints. This works ofcourse but it only brought to the fore the negative sentiment and not the overall sentiment.
With Feedbak, i try to capture the overall sentiment with the App via CSAT, NPS and dig deeper with text based questions. All fully customizable.
You can target by App version, Geo, Page wise without putting in extra dev effort.
Install once. No App update required later. Wide set of questions which you can change/add anytime
