Perfect Scientific Calculator
I have been searching for app that works closely to my Casio 9759 and TI-84. After download free version and spent 2 hrs to explore, This app is exceedingly my expectation. And I don’t hesitate to paid for lifetime version. It is money worthy and highly recommended.
A scam
My college professor said for us to get this app for our quantitative reasoning course, but for the one function that I need for half of the work I do, I have to pay for it, absolute ridiculousness
Please add history even after clearing
I enjoy using the calculator for school and have paid for the full version. Please consider adding history when you press the up arrow even after clearing the data.
for school
i hate school only have bc of it😡😡😡
Good emulator memory function faulty
Its a good app but after paying for it, it doesn't save anymore lines of calculations.
Excellent emulation
Feels and works just like a TI 84
Bought lifetime 7 years ago and now it’s unbought
My money is gone otherwise I would rate it 4 stars

Best Calculator App - Want’s to track me?
This is by far my favorite calculator app! It does everything! But… Why is my calculator asking to track me across other apps and websites? That’s it, I’m destroying everything I own with a network connection.
Amazing!
I legit stopped using physical calculator except on exams. Been using this for years. Great so u don’t forget how to use it 84. A,mazib product. Even the free version is great
Premium features are a second purchase
Ok so the app is $5 and it has ads??? There’s another $5 purchase for premium
Best calculator I’ve seen but has one problem
This is one the best calculators I’ve seen to be using for my schoolwork. However, the only problem is that the app crashes when the answer is a large number.
ya
Uma valente m*rda :)
功能缺失
为什么没有draw功能呢？2ND+ prgm变成了公制换算
One of the best calculator apps
I’m a huge fan of this program. I typically use physical calculators, but this one always serves me in a pinch, and it has excellent references like formulas. I cannot recommend this app enough for any practical mathematicians.
Can’t play music
Despite not having any sound come from the banner ads, the app will stop any music you are listening to every 5-10 seconds. Very irritating. Otherwise works pretty well
Good
Good
Loading screen annoying
I loved using this calculator app until the recent update that added a loading screen and full screen ad before I am able to use it. This makes the app hard to use quickly and made me look for alternatives.
Gay
Yo
I don’t like it
I’m gonna delete this the moment I graduate.
Delta Number
I need to know where we can change the delta number My delta is wrong and I dont know where to change it
Ads
I've been using this app for years, and the ads and boot time to go through the ads make it almost time to uninstall for my needs. I am quite disappointed.
Great calculator
Worth every penny. My new favorite.
Garbage
I paid for the app and ever since then it malfunctions. The app shuts off when I press enter.

Complete nonsense! Why would you need a subscription for a calculator?! Next thing you know, we'll have to pay a thousand dollars a year for a flashlight switch. Maybe soon we'll have to pay monthly subscriptions for underwear and socks too.
Just what I needed
Very similar to the Texas Instrument Ti 30 XS. Well worth the price of $4.99
The App Crashes
The app was crashing and I thought it was because it wanted me to upgrade. I purchased the upgrade and it is continuing to crash. It wont solve a single math problem before it crashes.
App
请问有安卓版吗
Error en de programación
Estoy enfrentando un problema específico al realizar múltiples operaciones. Cuando intento borrar solo la última operación para que no aparezca en el historial, el botón “DEL” no funciona correctamente. Esto me obliga a utilizar el botón “Clear”, que elimina todo el historial de operaciones, lo cual es inconveniente y poco práctico. Necesito una solución que permita eliminar únicamente la última operación sin afectar el resto del historial.
It’s GREAT!
Just like the real thing, and I have two Ti-84 calculators. I’m only giving ‘5’ stars because I do believe it could use some polishing up to ‘appear’ like the real thing, and I do believe that the creators of this app might be surprised at how many more apps they would ‘sell’. I always ‘purchase’ to get rid of ads, which are totally annoying. You would sell FAR more if you gave your buttons more ‘depth’, with dark tiny spacing to define the button away from its frame; the way it is, currently, is way too duo-dimensional. Add more depth and shadowing to where the cosmetics are more realistic and I would wager that your sales would increase to where people would pay for your product more than just wanting the ‘free’ version. Regardless, this is an excellent app - I purchased the ‘Lifetime’ upgrade!
Good except for 2 things
Doesn’t let you see anything from complex infinity answers, and won’t let you simplify certain answers.
Ứng dụng cần cải thiện thêm nữa!
Mong ứng dụng tiếp tục cải thiện thêm tính năng mới nữa nhé! Ứng dụng rất hay và tiện tính toán nữa!

Amazing
Calculator has every function you could possibly need at an amazingly low price. Useful for all my engineering calculations. A great resource when I am on the road or in the office.
Not working properly
After I pay for the app is closing and not giving out the solutions
great!
I still havent figured out how to calculate the root of a number in this but apart from that this thing is awesome.
