I bought Zonka Feedback, Qwary, and YouEngage knowing that there are similarities and some differences in each platform feature and the limits for their appsumo deals.

Within 1 minute of signing up I was offered:
If you provide a 100+ word review on AppSumo, Zonka will increase your Website Visitor Limits by 2x. For me that means 1,000,000 web surveys per month. WOW! Then if you leave a review on review and recommendation at G2 and Capterra, Zonka will upgrade you for free to all our new, upcoming growth plan features including Workspaces, Custom Report Builder, Custom Survey Link Builder, Language Translator and more.

For Zonka I like the following features:
1) Easy to use, intuitive
2) Templates that give us a headstart
3) cname
4) adding logic to survey questions
5) Mobile App for Android and iOS
6) KIOSK mode works online and offline (when offline it queues and syncs later) real time feedback and collaboration with team members (although it would be nice if the user counts were also increased with reviews)
7) Locations, where we can run location specific surveys and also assign users to locations. I haven't figured out how to limit admin users to a specific location yet. the admins see all locations.

For Zonka I wish for the following features:
1) I wish the 4 Offline devices limit is also doubled with reviews because I am not sure if we can have an unlimited number of devices running the iOS/Android app in Kiosk mode as long as they are online.

2) I wish they had a question type with numbers as the expected answer so we can do calculations and/or hidden calculated fields.

3) At first, I was excited to see additional language options in the survey builder. However, I was disappointed when I found out it did not auto translate my English questions to the other languages. You have to manually design each survey question in whichever additional languages you select.

Overall, I like this deal and I am hopeful that Zonka Feedback will keep getting better.
