Implement likes & dislikes in google appsheet

[yantong]

Hi,  i am doing a event app, using google appsheet. 

I aim to let user likes and dislike the restaurant and the like counts will use to sort the ranking of the restaurant. Any good idea to implement this function?

If you have an action button that increase the "likes" quantity, you can just add the qty with a simple action that updates the qty column like.. [Likes]+1.

Depending on how serious you want to be about your ranking you would have to consider preventing multiple voting. 

Requiring user login is the most logical way to ensure this but it comes with a price because it's not available on a free plan. There is Google form and app sheet integration but I'm not sure how that works in terms of user identification and pricing.

Perhaps you might want to consider using Google form instead of Appsheet. If I'm not mistaken Google form is available for free to capture user emails.
