## OneCalc: All-in Reviews in Canada

### ***** "Great"
Easy to use for us old seniors.
-- Dragoon 65, 2025-06-02

### *---- "Desperate"
This app was once good but recently it’s just plain awful. Ads popping while entering calculations and causing everything to switch to an unknown window of which could have malware and or viruses. The entries also grow in size sometimes to expand beyond the screen size.
-- 5TZp428y, 2025-02-28

### ***** "Super good it’s good for gyatt skibidi fizz Ohio pickle"
UwU gyatt my name is da rizzler by the way I wuv gyatt so much.
-- Tupac zz. Zz z, 2025-01-10

### *---- "Really stupid keyboard"
Since when do the keybosrd numbers and signs have a line underneath them? + (plus) turns into a plus-or-minus sign and the  - minus sign looks too similar to an = (equal) sign.

The = sign with its line underneath it, is three lines, like the menu sign.

Were these turkeys in drugs when they did this? Idiots!!!!
-- Dickie Halberg, 2024-06-27

### *---- "Misleading"
Does not include all that it says it does. 
Have to get additional apps.
-- TakenWhooo, 2024-06-24

### ****- "Good calculator"
Good calculator with a surprise ad
-- Presalesingh, 2024-06-20

### **--- "Paid for upgrade but not working"
I paid for the app to remove the ads, but the only way to access the paid version of the app is to open it, wait for the ad to finish, go to the settings, click the button that says Buy-upgrade to ad-free version, which opens it in the App Store, then shows me the option to open the app. When I open that it opens a new window, so I now have two different versions in separate windows from the same app on the App Store. It’s annoying and frustrating to pay for something that doesn’t work.
-- Sunkizzed, 2024-04-29

### *---- "Ads"
Way too many ads that interrupt your work and the only way to regain the app is to close and restart. Any calculations you’ve been working on are lost. Dumb app if you ask me
-- 5TZp428y, 2024-03-27

### ****- "Surprised by the Ad."
After I gave the calculator 5 stars, I got a surprise ad.  It changed the calculator to a video.  I had no idea how long it would last or that it was even an ad.  

Calculator functions very well.  To find square root you push the square root button first and then the number.
-- RSB123RSB123, 2023-06-29

### ****- "Nice app"
It’s useful. I hope it was more scientific.
-- Fr. Jean, 2023-06-22

### ***** "Rabia"
Mujhe pyaar hua tha
-- degrassi rabia, 2023-06-18

### *---- "why do you have to hit equal key after every action???"
why are there so few calculations where you can presd 3 times 3 plus 6 divided by 5 and get 3 for an answer
this is not one 
most give 10.2 as an answer
-- 1dffhghuyhrhhhhtg he e, 2023-05-08

### ***** "Like home."
95% identical to the calculator face I used for 4 years of tech school and college. For me this is a no brainer. Well done.
-- 22salburt, 2022-12-30

### *---- "It’s Rediculous"
Who would pay for such basic “technology”?.
-- NAK47, 2022-04-07

### ****- "Good for school stuff"
It’s good :p that’s it ig- sooooo yea it’s good
-- i justarandomgirl, 2022-01-20

### ***** "Love it"
I use this for many functions and this App does it all
-- Pc14634, 2021-08-08

### *---- "Wrong result for simple multiplication"
I almost got into big error using this Calc. 20x60=1.0! Can you imagine how it can be disastrous.
-- CheongGan, 2021-03-18

### **--- "Keyboard input"
I’m not sure what’s going on, but something like 3/4 calculator apps for the iPad don’t allow numerical input from the keyboard. 

I want to give no stars but I delete immediately and so didn’t give it a fair shake otherwise. 

But still? I’d love to use my keyboard.
-- yoink, 2021-02-20

### ***-- "Get rid of adds :("
Great calculator, but deleted it after using it twice due to the adds.
-- citradellic, 2021-01-27

### ***** "It’d be better to add a Foreign exchange function"
Possible?
-- 张山, 2020-12-23
