Thanks again don’t change nothing. Best app ever. ### 3/5 — Good app *2015-07-10* I like this app. It could be improved if the app user could put in extra fields, like truck charges, and itemized parts. Hopefully this will be changed in the future! ### 5/5 — Wow, what a time saver! *2013-09-18* I get kind of excited every time I finish a job now cause it means I can use ServiceCalc again!

I would recommend to any service employee who has to write up invoices on paper every day! ### 5/5 — This app has helped me in life. *2012-12-14* This app has helped me build many things, mainly happiness though. Sometimes I take my phone in to the bathroom while I take a shower and the phone screen builds condensation. I no longer hold my breathe thinking about when the next awesome calculator will be released. I hope the developer is as handsome and strong as this app makes him/her out to be. I couldn't be happier with my purchase. I would also like to say there is a flashlight which helps me when I travel to dark places. One thing I would like to be added would be animal pictures for the buttons such as a dog instead of the + symbol. Other than that, A+++ ### 5/5 — My life made that much easier! *2012-12-08* Excellent app! Makes it much easier to write out invoices for work. Also helps giving customers an exact amount!
