There is no large cooperation to present boring facts about, so I am giving some less serious trivia about me as a developer instead. The information below is of course completely unnecessary to appreciate the apps, but someone might find it fun to see what leads up to a collection like this.

After a Ph.D. in Aerospace Engineering in 1985,  I began as an Associate Professor in Solid Mechanics at the Royal Institute of Technology in Stockholm. But after a few years I decided to leave the University.  After a short stint at IBM I spent eight very stimulating years at Apple Computer, mostly in marketing management positions. Since Apple I have been self employed with a very varied range of assignments, from management over marketing to technical development. Working with marketing and advertizing made me interested in graphical design, and that is why I am dabbling with the app graphics without the proper background.

About 5 years ago, at the age of 55 I decided that I was too old to have budget restrictions and clients telling me what I could do or not. So I started developing these apps completely on my own, with no financing except my own time, a lot of time 🙂 I am only working with applications that interest me personally (thus a lot of sports) and that are complex enough to be a challenge. I has been fun and very stimulating to work with all the aspect of the creation: Idea, design, graphics, programming, testing, video production, documentation, support etc. All the positive feedback and ideas I have received from users has also been very rewarding (thanks to everyone).

  1. Your app helped me blow the minds of my track coaches and athletic director. In the past they had spent thousands on complicated and poorly supported fast cameras and software that was a hassle to setup and use. Your Photo Finish and Starter combination yield instant, accurate results well beyond what they were getting from all this and manual stopwatches before. Your app allowed me to run the timed track events alone with only minutes worth of training for the starters. Thank you.

    I am curious if the photo finish result would be better if using a device with a faster claimed frame rate. The new iPad Pro for example, has a claimed rate of 240 – will this improve the accuracy/clarity of images in 100m running events for example? Have you tested such devices?

    Secondly, the backing board and finishing line we use is white. The text overlay for the Mark is also white. Is this something that could be an option in future versions for better contrast?

    Thanks for a great product. All our tech coaches saw it in operation today and I’m sure they will promote it among their PE teachers and coaches as well.

    1. Thank you for your positive comments.

      Yes, newer devices with higher frame rate give a little higher accuracy (and nicer images). Check the accuracy post in the blog for some details. There is also an item in the Q&A in the app about it.

      I know that white not is optimal in some cases (no single color is). I have it on the todo list, I just want to find a way to add it without cluttering the interface.
