2. How to develop successful products.
First of all, it's critical to determine the level of interactivity for the app. For instance, what features will, and more importantly, won't be included. Establish the genre for the app (e.g., games, children's books, reference) and then be extremely careful to eliminate any "feature creep," unnecessary ideas that increase development costs, but add little value. Strive for "Five Star" ratings from customers, a vital component to an app's success. The more positive ratings, the better longevity for the app. For the children's market, the key to developing apps is to make them so user-friendly that even toddlers can manipulate the apps by themselves. Properly designing your touch screen interactivity is essential. Always design with navigation tools that are straightforward and features that do not take away from the essence of the app. For example, I've found that excluding games and animation in our children's book apps make them more successful in the long run, as the core focus remains on teaching kids how to read rather than simple entertainment.
3. How to estimate your ROI.
With the way the app market is structured, there's a good chance no one will notice your first app, and it won't be profitable. The key is to develop enough apps and to learn with each one, repeating the process until you find your niche and start turning a profit. Once you have a half-dozen or more apps, you'll get a good feel for the return on investment (ROI) on your specific apps in their particular space.
This is a crowded marketplace that is growing tremendously each day, with more than 400,000 apps currently on the App Store. Apps are price-sensitive, and low prices are encouraged. Apps that are 99 cents are competing with others that are $3.99. You can strategically play around with pricing, offering a special introductory price or putting the app on sale for a specified time. These tactics can help the app get noticed by consumers. In fact, many users regularly look for an app to go on sale before purchasing it.
