BEST. DEAL. EVER.
We are currently developing a SaaS app for the dental industry. I am not a developer, but I've been able to do some amazing things with this. Tool tips, hotspots, notification bars, video tutorial slideouts, and so much more. This will really have an impact on the user's experience. I have literally saved thousands of dollars (trust me, I've done the math) in developer fees with Tooltip.io, and I'm just getting started! Not sure if I will need thousands of MAU's, but I'm not gonna risk it, I've already stacked some codes, and I will surely stack a couple more before the deal is over.
FYI, this not only works if you have a SaaS app, it also does pretty amazing stuff for a normal website. Installation is a super simple. I used Google Tag Manager to get the code up in not time.
If you are on the fence, just do it. Buy a code (or several). Use it. Love it. Make money. Thank me later.
