Hands down the best calculator around the HP 10bii has always been your best choice for all tyoes of monetary calcs...it's been my choice for decades and you guys have gone above & beyond with this app!!! Keep it up!!!

★★★★★ Nick D8653 · Dec 14, 2021

This is a great financial app - there has been an issue with Google play the past couple of days that have been resolved - don't let this discourage you from using this app - I have been using this for years and once you get used to using it you won't be able to live without it - also, Kenny was a great help and very responsive during the issues with Google play

★☆☆☆☆ Indira Dejarnette · Jun 9, 2021

WT Heck Bought it struggled w Google play till 330am won't download just says refund or install. With each time I click install it wants to rebill. Account checked paid now no app and needed for all day RARE opportunity training told by 2 experts retiring soon to get. There's a free calculator they said could be alt this morning SMH. This could be a hit for hundreds of thousands when people have bad results everyone switches.

★☆☆☆☆ Lloyd Samsonite · Jan 5, 2022
