I really resonate with EvilT's review. I was really surprised that basic functions like downloading results or pushing to google sheets are not included without extra payments. So the first time I bough this deal I was frustrated enough that I returned it almost right away. It felt like a bait and switch and I really didn't like that.

But, I came back to it. Zapof is a powerful tool. The save and resume functionality combined with the option for .pdf download for individual form fillers, along with a relatively powerful calculation within the tables, lookups within the forms, and show if capability, were too good to miss out on. It's not exactly easy to work with especially when making lots of changes to existing cells, but it works really well and I've already integrated it into one of my workflows and am appreciating the results.

Like EvilT said, I want to be able to stack codes to get functionality like download, and google sheets, and CNAME. In terms of upgrades, I did like the concept of being able to select from a menu of subscription add-ons or choose from a subscription level. But the reality is that it's hard to imagine myself paying for the monthly subscription for those features - if that's the situation, I'll just use other form builders to avoid that and limit my use of this one working in the areas that it uniquely excels in. But if I could stack codes for some of those upgrades and more forms, I'd definitely be interested.
