## Scientific Calculator fx-991 Reviews in Пакистан

### ****- "Features"
Please update matrices in next version its outstanding but lacks matrix functions
-- Raouf Bangash, 2025-01-14

### ***** "Extremely amazing experience-I’m love in it.❤️"
100 💯 recommended.
-- Muhammad@19, 2024-10-07

### ***-- "Split View"
I can’t use Split View with other apps otherwise I would buy this app
-- M. Asim Ali, 2024-05-26

### ***** "Best minimalist scientific calculator"
I love the minimalist design of apple’s own calculator app but it was lacking the feature i use most “natural textbook display “ this app does that and much more. It also has no in app purchases or any other bloatware and doesn’t even gather any data. Hats off to developers. It can be bit more minimalist like apples calc and a night mode would be awesome plus the landscape mode.
-- Abdulmoeed, 2024-02-01

### ***** "It would be awesome if you could a night mode"
Option to have another theme with black keys would be awesome
