## Calculate84 Reviews in United States

### ***** "W"
Best calc app
-- CPSaki, 2025-01-03

### *---- "Makes mistakes"
This app makes mathematical mistakes! I thought I was making mistakes, little did I know that there is errors in the programming for this calculator! It was a simple average I was doing too.
-- Explorationsofa, 2024-12-27

### ***** "I have a TI-84 but. . ."
I find this app very convenient because I put it on my iPad and iPhone and it is way easier to use that my actual TI-84
-- IzzyRM, 2024-12-25

### ***** "Good app"
Good app for what you need in high school math
-- Hugo6⚽️🇫🇷, 2024-12-18

### *---- "Stupid pro"
Recently it made the calculator have pro features so it is simply un usable for normal usage unless you want to pay 30   a month. absolutely ridiculous i hope this app falls off.
-- Your Are Loved, 2024-12-17

### *---- "Ads"
Why ads for a calculator like honestly
-- AbroadElm, 2024-12-12

### ****- "Pretty good for a free app, one major problem."
This app has helped me immensely through my statistics class. There is one problem I have however, and it’s that it seems the “Picture” and “Statistics” labels under VARS are just straight up missing. This is unfortunate as it makes it more difficult for me to find variance.
-- Dontclickonme, 2024-12-12

### *---- "Doesn't work"
I paid for a years subscription and my subscription isn't up until 2025 and it's not letting me access the pro version. It keeps asking me to restore my purchase but when I put in my Apple ID and password it doesn't update. Total waste of money.
-- sbarboza707, 2024-12-09

### ***** "Great app—identical to the physical calculator"
This app works great, and the ad is not at all distracting. It works exactly the same as my physical calculator and super helpful!
-- A Sock Full Of Doorknobs, 2024-12-05

### ***** "Perfect App and great price! just missing one feature"
Needs to have an area to enter confidence level for 2samp z test, 2prop ztest, etc. Otherwise incredible app
