I am delighted to announce that TripNI has now been released on the Apple App store and is available as a free download.
For more information on the app head over to tripni.co.
As a developer I love to makes peoples’ lives easier. In particular I am fascinated by how ‘smartphones’ can offer new opportunities to enhance how we interact with the world. One such opportunity is the ability to change how we travel and find our way around.
Which is why I’m extremely excited to finally talk about TripNI - a mobile app which aims to help public transport user’s in Northern Ireland utilise our bus and rail services.
TripNI will initially be launched for iOS devices (iPhone, iPod Touch and iPad) - with an Android version to follow. If you would be interested in testing the app in the coming weeks then feel free to sign up as a tester.

A side-effect of developing apps over a long period of time is that you begin to see common problems that must be solved in numerous apps. Describing dates is just one such example. When I wrote my first app Simple2Do I needed a way to desribe to user’s when an item from their to-do list was due. I found the most comprehendible way to achieve this was to describe the time to/from the task in a single unit - i.e. the number of hours, minutes, seconds, days, months or years until the task was due.
Fast forward a couple of projects and I began work on a Twitter client which displayed the user’s timeline. Again I wanted an easy way for the user to visualise when something happened, in this case when a tweet appeared in their timeline.
The second time I encountered this problem I decided to code up a little utility class for creating these descriptions. The result was RelativeDateDescriptor, an objective-c utility class for producing human readable descriptions of date intervals which is now available open-license on Gitub.
Here’s an extract from the project README with some examples…
RelativeDateDescriptor *descriptor = [[RelativeDateDescriptor alloc] initWithPriorDateDescriptionFormat:@"%@ ago" postDateDescriptionFormat:@"in %@"]; // date1: 1st January 2000, 00:00:00 // date2: 6th January 2000, 00:00:00 [descriptor describeDate:date2 relativeTo:date1]; // Returns '5 days ago' [descriptor describeDate:date1 relativeTo:date2]; // Returns 'in 5 days' // date1: 1st January 2000, 00:00:00 // date2: 1st January 2000, 00:00:18 [descriptor describeDate:date2 relativeTo:date1]; // Returns '18 seconds ago' descriptor describeDate:date1 relativeTo:date2]; // Returns 'in 18 seconds'
