## Pascal: 3-in Reviews in United States

### ***** "Love it"
Great calculator. From easy to complex tasks
-- Ajax1949, 2020-10-15

### ***** "Perfect Calculator App"
I have been using this app for many years. No other calculator app pays as much attention to both function AND design like Pascal. It’s a beautiful calculator.
-- RRossier, 2020-10-14

### ***** "Simple use"
Great app!
-- R2D2-Lafuente, 2019-12-06

### ***-- "Update: problem needing resolution"
This was my favorite minimalist app until just now when the premium version I had installed reverted to the basic version. This happened immediately after I tried the new OS11 dark theme. DON’T DO IT YET! Then reverted back. Developer, I can’t get ahold of you but could tell you how to replicate the condition. Please fix. Will revert to 5 stars when fixed. Three for now because this is in total a major function and aesthetic loss that I can’t undo. Part Apple’s responsibility; part developer’s. Also, can’t find you on Google App Store. Are you there?

Ready to be resatisfied.
-- TheCyberHunter, 2017-12-17

### ***** "Great Calculator"
I like the vertical format for scientific mode.  Has a lot of functionality.
-- Former Admirer, 2017-09-27

### ****- "Money-quality"
Though it cost money for the Graphing section, it has a well put feature for you to test it out before actually buying it same for the Programming configuration. If I remember correctly I think the app costed money, but I dont remember, but I think it's worth buying and all( the best calculator I've ever ran into) it's quite useful when or not my own non-phone graphing calculator dies and it's just fun and super easy to use this app. Also to get the other features besides the standard scientific-Calculator is $1 I'm pretty sure that's a good deal. Worth it every way, but every app needs improvement and anyone can help the developer do that. 🔗
-- Flying fruit, 2017-05-13

### *---- "ITS A TRAP!!!"
Free calculator app that makes you pay for the reason you installed the app(the graphing calculator and programming calc )
-- galaxydigger, 2016-08-26

### *---- "Why does graphing calculator cost money"
Why would it cost money when clearly in the video you can use it for free. If you want a free graphing calculator then do not get this app.
-- the_cob5283, 2016-04-19

### *---- "Don't waste your time"
You have to pay to get the stuff that the default calculator doesn't have. Waste of battery life downloading this
-- Game lover74, 2016-03-08

### ***** "I personally use it way more then the school calculator"
I think it's super handy and fast I use it for graphing in physics and it never fails me it can do all that the school calculator can do ( graphing wise )
-- CatoSenpai, 2016-02-18
