I started developing the app while I was an undergrad. So yes and no, I wasn't totally new to programming, but didn't have any professional experience beforehand.
It is getting the UI right. Scientific calculators have tons of mathematical functions available and you want them to be easily accessible for the users. It has been, and still is, quite a challenge to create an interface that's not too cluttered and still has everything. There were many revisions, often I had to revert changes because it turned out that most people did not like it. Even though I tested each update beforehand, it is super hard to create something that is good looking, easy to use and functional at the same time. I have increasing respect for UX designers every time I touch the UI. Speaking of which, there is a new UI update coming soon that should make everything accessible with fewer clicks!
Marton, the interviewee and the developer of this app, is a PHD student in Machine Learning at Eotvos Lorand University. He has over ten years of app developement experience and his apps have over 2 million app downloads on Play Store.
I'm not a big smartphone user. My most used app is Firefox, I try to keep tracking to a minimum. Other than that, I have the usual messenger apps to keep in touch with friends.
It's been nearly 10 years now. There were times when I did not have that much time beside my day job to develop it and times when I could spend significant amount of energy on it. However, I don't plan to ever give up on it, I love the positive user feedback and making the app better and better.
Contrary to the current state of the Play store, there were no graphing calculators available ten years ago. That was the original goal, since then it changed to providing the best possible experience in a math app. Right now, I'm planning to add some small knowledge base so people don't have to leave the app and can look up formulas right there when they need them.
I'm trying to stay ahead of the competition by always adding new features and making sure everything is as smooth as possible. People have enough trouble learning math, the app shouldn't impose more problems. You should spend your brain capacity on solving your homework, not on remembering in what format an app requires its input.
Currently I'm working on a redesign that should make the built-in functions and constants more accessible and searchable. It turns out, one of the most important features of a calculator is its keyboard!
Please send me feedback on how you use the app or what feature would you include! It helps a lot knowing what problems people have and where the rough edges are.
Algeo is the most beautiful scientific graphing calculator available on the Play Store. It's fast and powerful and you'll never have to carry around a large physical TI calculator anymore. The intuitive interface shows your drawn functions as you would write them on paper rather than squeezing everything on a single line. And you don't need an internet connection unlike other graphing calculators, it works offline as well! Useful for calculus, physics or to solve those x+y equations.
Wolfram Alpha users love using Algeo! This free app is packed with more features than a big TI 84 graphing calculator. Solve your homework with Algeo: draw functions, find intersections and show a table of values of the functions with an easy to use interface.
As a calculus calculator
• Symbolic Differentiation
• Calculate Integrals (definite only)
• Calculate Taylor-series
• Solve Equations
• Draw function
• Function plotting and finding roots of functions
As a scientific graphing calculator
• Trigonometric and Hyperbolic Functions
• Radians and Degree Support
• Result History
• Scientific Notation
• Combinatorial functions
• Solve linear equations (x+y)
• Do everything what you can do with a ti graphing calculator
• Number theoretic functions (modulo, greatest common divisor)
As a free graphing calculator
• Draw up to four functions
• Analyze function
• Find roots and intersections automatically
• Pinch to zoom
• Share your plots with your classmates
• Create an infinite table of values for a function
This graphing calculator is the easiest way to analyze a function and integrate and differentiate equations. Useful for math classes in high school or university. Take the Calculus quizzes with confidence knowing that Algeo helps with all mathematical functions. It makes integrating a breeze.
Wolfram Alpha users approve! Algeo is the best scientific calculator for Wolfram Alpha users.
