Formula Solver

Doesn't work on Android 7

Thanks for making this app! I have been looking for it foever. My HP 200 LX is getting old, and this fuctionality, is something I use a lot.

This is not a solver but only a calculator for an entered formula. From a solver I expect that I can input any of the variables in the equation and it will solve automatically for the variable left blank. It needs to allow for multiple equations with independent variables. So it has one advantage.... Variable names can be complete words, not single letters only.

This app is exactly what I've been looking for. It replaces the functionality of my HP 19Bii calculator SOLVE feature. It allows me to create any equation using my own named variables. Then it will solve for any of the variables as long as I supply all but one. It also allows me to save, export, import, my formulas. I am an engineer and this is fantastic. Feature Request: -Allow the use of numbers in a variable name, ex. Height1, Height2 -Allow for use of period symbol "." in a variable name, ex. Color.1, Color.2

This app work great. Simple interface and easy to use.

I've have been looking for a program like this for a long time. I can enter my own formulas I use all the time without having all the others I don't need. I can customize my input and output. It not just a number converter(convert.exe) like the other reviewer uses this allows multiply custom inputs.

Good concept but doesn't calculate compound interest correctly using P*(1+R/400)^(4*Y) I've assumed quarterly compounding.

Would be great if sine cosine and tangent where included. App has potential but minor stars until improved...

I am a pediatrician and use this app to quickly calculate the "custom" mixing of infant formulas for babies who need formula of increased caloric density. Easy to use. I was able to configure formulas immediately without consulting any help files. Nice job.

Would be better if I didn't have to add even the most basic formulas. Add some basic formulas and conversions. I use convert.exe for years. Try something like that.
