This APP has helped me very well, it is very easy to use, it is worth recommending, and the customer service answering speed is very fast!

***UPDATE***
After the snarky response from the developer, I decided to update my review. I would also like to point out we did open support tickets and brought these issues to the attention of the app developer first, but received a similar response from them. The app works but is severely lacking for businesses that care anything about metrics. It also can create a nightmare for coupon management.
We installed the app across 2 stores and experienced the same issues on both. While technically the app did it's job in email capture, there are better options available.
Issues:
1) You cannot measure true campaign performance. The app will only track overall number of coupons provided and how many were used along with dollar value of those orders. You can't measure down to the "slice" level. So you won't be able to answer simple questions like: How many 15% off codes were provided? How many were used? How much revenue did that generate? Did the 10% off codes do better or worse?
***Response to developer*** My issue is based on a company that measures sales performance. If you have companies that DO NOT care whether a 10% or 15% off coupon works better, that is on them, but most companies need this whether they report it to you or not. Being able to see something like 1000 10% off codes were provided but only 2% were used vs 500 15% off codes were provided but 10% were used is vital information when running discounts. 2) Each dynamic code is created as a separate coupon code in Shopify. Several other companies will create a parent coupon listing (ie Save 10% OFF) and the dynamic codes will be compiled under it. This helps keep your discount section from becoming overly cluttered. 3) Codes are not created with an expiration date, leaving them open liabilities. When you create a campaign in the app, you would think the codes created within that campaign would have the same expiration date, but they do not. We ran a campaign for a few weeks around Nov/Dec 2020 and now have to go through THOUSANDS of coupon codes and manually disable them.
***Response to developer***
Setting an expiration date on dynamic codes wasn't an option. We set expiration dates on every code we ever create because we consider them open liabilities. 4) URL targeting can't utilize wildcards which is an issue if you have marketing variables in your URL (ie from emails or other campaigns). The URL had to be an exact match.
***Response to developer*** My issue here was based on a response from your team on a ticket we opened, so no, your "contains" variable did not work on either of our sites so we had to use the on page load option.

Love the app. Actually just installed a day ago and I've already generated enough revenue to cover the cost of it for the remainder of the year. I had some questions during set up and they were all answered in a timely manner. This app comes highly recommended from me!

i use this app for receivent emails and im really satisfied with it. It is easy to use and it has a lot of options

It has helped as a great lead magnet and for additional sales. I also like how it is not too intrusive, it doesn't pop up all the time.

Was a bit put out that I had to set up a new campaign to have the latest version of Wheelio active on my store but I'm glad I did. Wheelio2 is awesome, easy to set up and the look and feel of the App is much better than the older version. Sam at Wheelio was super helpful with the new set up. I think it will convert better also!

I ditched a hot garbage banner this morning and SO VERY THANKFUL I FOUND WHEELIO2.0! Man...this wheel is amazing! And the customer support is even better! I was up and running in no time! No for all you coffee nerds out there...go check out Wheelio 2.0 in action my site: bitbytejava.com !

An amazing support team to reach out to, also an amazing, high-performing app. I definitely recommend anyone who's interested in increasing their conversion rate to look into this app :)

by far the most impressive gamified app wheel I have used on my store! I have used this app for over a month now and it's aesthetic is absolutely AMAZING!
I had 8% of the subscribers I have now when I first started with Wheelio, and my conversion rate was literally 1-2% MAX and with Wheelio vs other Gamified apps i've used, I have seen my conversion rate of ATC's go up about 5x every store I use this application on. If you're looking for an app which has presets, a great look ,easy to use and set up, I'm talking like , I'm continuously amazed by this Application, Wheelio has really set the bar high for Gamified pop ups and it was the first one so that really makes me understand why it's such a high converter, with time they have made this app literally a behemoth of an amazing top 10 shopify app I would use, if you are new to shopify which I would recommend over other hosts for your shop, then my favorite in my top even 3 apps without making your costs too high would be to download this gamified pop up ap, wheelio never ceases to amaze me, from store to store, they have fast support, always helpful , multiple different games so that you can capture email, phone, and any information. Multiple integrations,a and I mean, I cant believe it, it's really a spectacle of an application!!!!!! I will always be a shopify, and wheelio uiser, all the other gamified pop ups look so bad to the user, and I see maybe 3% of the conversions Isee compared to the ones I see with Wheelio THANK YOU TO WHEELIO!!! THE WHOLE TEAM! It changed my store from a small time store to a huge store, and continues to do the same for every store. If you're new to Shopify, or a user looking for a gamified pop up app, or top 10 recommend, top 5, even the only application for data collection of users so you can do marketing on shopify, this is by far the best one to use. TRUST Me, and thank me later by checking my site out!

Yes it is ugly, yes I hate websites who have it, yes it may look gimmicky...but deep down, it increases conversions and works!
