Useful Formulas are live and ready for beta testers! 🚀

Hello Indie Hackers,

I would like to invite you to try UsefulFormulas.com

Your feedback would be much appreciated!

I'm sure there is a lot of work to be done yet, but can't wait to hear your first thoughts on the app.

Those, who will find time for test and give constructive comments, will be granted with an increased trial limit. 🎁
