## OneCalc: All-in Reviews in United States

### ***** "Perfect!"
With husband being  retired from construction he sometimes helps friends. 
I am retired from being a Tax Commissioner and owning a private accounting business. 
Many times I will receive a call for help. 
This app allows both my husband and I to complete tasks required to assist others. 
Perfect and the ads are minimal. Thank you!
-- LoveQuilt Lady, 2024-12-30

### ***** "Best thing 🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂🤯🤯"
I’m 7yrs old and I still love trying to learn algebra because I have borrowed a dictionary from my grandpa and I know what “e”is; 2.71828*.       *Perhaps a two?????????????????????????
-- I am 7!, 2024-12-30

### ***** "Big fonts"
He should use easy to read thanks.
-- Papabearsmith, 2024-12-24

### ***** "OneCalc"
OneCalc is the best app ever. :D
-- & nhvuteiuhvtirbyuitrth, 2024-12-16

### ***** "This is the best calculator"
Because there is a lot of everything there, there is a percentage ratio and prices and this is only a quarter!
You really need to download the app.
-- DinosMinos, 2024-11-19

### ***** "Great app!!!"
So good and it was easy to access
-- Yazmine G, 2024-10-23

### ***** "Review"
It is everything
-- Ericbananaz, 2024-09-29

### ***-- "Dividing by zero isn’t infinity!"
This is trying to teach my kids bad math.
-- parentofgamers, 2024-09-24

### ***** "Excepcional"
LA MEJOR QUE HE PROBADO
-- nacostermaterno, 2024-09-12

### ***** "FINALLY !!!"
It took me waaayyy too many downloads to find a scientific calculator with no ad banners lol. This app checked all the boxes !

This is definitely the best; love that you can change the appearance of the calculator to make it look like your typical Apple calc / between two other aesthetically pleasing options :) 

Plus the ability to earn ad free for 7 days at a time is wayyy more user friendly & I don’t mind it at all. 

I’m also beyond glad that it supports split screen mode !

Thank you for making a fully functional & user friendly calculator for iPads :)
