I’ve spent part of my development schedule over the last few months rebuilding the iPhone app for NYC based startup Clean Plates. The Clean Plates iPhone app v2 is now available on the app store so check it out. Clean Plates offers professional restaurant reviews and a series of email newsletters with a healthy eating focus. The app allows users to search nearby or by neighborhood to find restaurants (think Yelp’s app but with more advanced filtering options and only professional reviews).
From a development perspective it was an interesting project in one way in particular: it was a brand new re-write of an existing app. Why re-write instead of extending the existing code base? Read on…
The old app was originally built several years ago and consisted of 475 classes and 79,889 lines of code. If that sounds like a lot of code that’s probably because it is. Because of it’s age there was no use of Storyboards and art assets were fixed in size (no Auto Layout). Combine this with poor performance, frequent crashes and heavy usage of an old un-upgradable version of RestKit and you have a perfect case for a brand new build.
The new app uses Storyboards and Auto Layout so it is compatible with the newer, larger iPhone models. It has been redesigned to be more in line with iOS 7+ style guides and even has more advanced features, including better restaurant filtering and the ability to save favorite restaurants. It is also only has 52 classes and 6,910 lines of code. With the new updates I tried to not to leave any existing users behind so it is still compatible with iOS 7.1+ devices, including hardware compatibility with the iPhone 4 and it’s shorter form factor. Finally, there are no major dependencies on third party libraries such as RestKit so future upgrades should be relatively smooth. The app is not perfect and at least one update will be needed for minor improvements but I consider everything here a big win.
