I work for a Carsharing company and we use Outgrow to easily make calculation tools where people can quickly see if a shared car is beneficial for them. They are super easy to make and can be duplicated and modified within minutes. This allows us to scale our company more efficiently. Our company is relatively small, so every euro has to be spent wisely. The Freelance package offers enough for us to do exactly what we want to do with our calculations. I've done some research into alternatives, and I find that the competition is not on the same level. I recommend this software to anyone that wants make basic or advanced calculation tools for their website within a few hours.
The reason for the 10/10 is that the one time I got stuck within Outgrow, their helpdesk was able to fix it within a few hours. The calculator wasn't displaying properly and I don't have the technical know-how to resolve the issue myself, but with the support of Outgrow I got it up and running the same day.
I'm looking forward to any updates that this software will have in the future to get even more value for my money.
