Faulty calc
Exponent multiplication and division doesn’t work properly
Excellent
Very good calculator. Has all the features I want.
Price ok, ok simulation
price was $8 to purchase full version. It's a good calculator but not 100% accurate simulation of the TI-84 (zoom button missing) which makes it not as useful for teaching students how to use a graphics calculator over zoom
Handy calc
Helped me to get through my numerical Analysis class
Mode button
The mode button appears to just access settings rather than a mode. Is there vase N calculation in this like in your other calculator app?
Muy bueno la verdad
Estoy en 8th grado. Estoy tomando cursos avanzados por mis niveles de entrenamiento, pero la verdad al principio me costó pero descubrí esta app y me a ayudado a hacer mis tareas mejor y practicar para mi examen de regents ☺️☺️
Best Graphing Calculator Ti84 replica
Very easy to use and full of great functions, that are consistent with a TI84 seriese calculator.
There right
This is the best free app.
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
