AppCraver recently spoke with Balazs Faludi, the developer behind Numerus. He answered our questions about developing apps for the iPhone and iPod Touch.
1. When did you start developing apps for the iPhone?
Balazs Faludi: I was very excited when the iPhone SDK was announced and decided to start developing as soon as possible. I bought my first Mac the day after the iPhone SDK was released. It took a while to learn Objective-C and see how the iPhone works, but after a few weeks I knew enough to start my first real project.
2. What was the inspiration behind your app?
Balazs Faludi: I imagined how cool it would be to have a real native plotter app with the same multi-touch gestures like the maps or photos application. To do this I had to find a way to interpret and calculate the expressions the user wants to be drawn. So I decided to develop a scientific calculator first. Soon the calculator became the main project, but I hope I can add the plotter soon.
3. How did you settle on your price point for the app?
Balazs Faludi: When I started working on my calculator, I wanted to create a $10 app. I had a lot of ideas for cool features, but unfortunately I didn’t have the time to implement all of them. I decided to release this first version with a much lower price and keep updating it with new features, if it’s well received by the users.
4. How did you like the developer tools provided in the iPhone SDK? Is there anything missing?
Balazs Faludi: The iPhone SDK is not perfect but it’s getting better. Apple did a good job with the documentation and there is plenty of resources on the developers website. I missed a way to communicate with other developers and exchange our experiences, but luckily Apple just dropped the Non Disclosure Agreement (NDA).
5. Is your company privately owned? Venture backed?
Balazs Faludi: I’m a student of computer science at the University of Basel in Switzerland and I develop my apps in my free time.
6. What are some of the other iPhone apps that you like?
7. What kind of features should apple implement in future versions of the iPhone / SDK?
Balazs Faludi: By now it’s not possible to change the startup screen shot programmatically which makes it difficult to create applications with multiple skins.
8. Are you working on any other apps that you will be releasing soon?
Balazs Faludi: I’m working on new cool features for Numerus, like the plotter mentioned above, the possibility to connect two devices on the same network to exchange data – and a lot more…
