I was in need of a customized form for calculating rent based on market value of a property. I was inclined to use sliders for the best customer experience and found the Loan Repayment Calculator.
The standard and already available forms were good in themselves, but I needed some specialized functionality with interdependent sliders etc. I thus contacted the team for a custom form and received very swift feedback from Graham.
All in all, the communication and collaboration to create the sliders I had envisioned, was on point and I cannot say anything else but that I am extremely satisfied with the level of service and invaluable help. The final product meets all my expectations and requirements.
To anyone in need for a great form with slider functionality, I highly recommend the use of the Loan Repayment Calculator with Apllication form.
I really like this plugin, simple and powerful. Would like to see an option for more advanced interest options though. 4 is pretty limited.
Great plugin and great service!
It seems like a great plugin for loan applications and calculaters
