Robert Wohnoutka is an independent software developer with over 20 years of software development experience. He currently has 11 iPhone apps in the Apple app store.
Robert is a former Apple employee where he learned the importance of ease-of-use which is the first rule he applies in all the apps that he develops. He also has over 20 years of Product Marketing experience with high-tech products where the ease-of-use aspect was his guiding light as he helped companies develop and introduce new technologies into the hands of consumers.
My Walks is a good example of an app Robert developed where he applied the ease-of-use principal to a GPS-based walking application. This app only requires the user to tap a Start button to start the walk and the app will automatically detect the end of the user's walk should the user forget to tap the End button. My Walks was featured in the Best Mobile Apps 2013 book by Jeremy J. Warner and published by Portrait Health Publishing Inc. Robert has also developed a version for bicycling named My Bike Rides and a version for skiing named My Ski Runs.
Robert has developed a number of very easy to use money management apps including EZ Adder, EZ Adder II, EZ Balances, EZ Balances II, and EZ2Compare2. He also develops customized apps including an iPhone app for his dentist's clients called Nikki Green DDS.
