This is my third review of target scan. You can read my previous review below. The short version of the review is “Get it!”.
The latest version of target scan is a big step forward in terms of accuracy from the previous versions. While I was enthusiastic about the previous versions, this latest one is the best yet. Over the past month I was able to do a statistical evaluation comparing scoring results between target scan and the system used at the olympic training center in Colorado Springs. Even though both systems operate on different technical principles the scoring accuracy and precision was virtually the same. Understand that the latest version of target scan will never replace the scoring systems used in international competition, they are designed for different users, in term of accuracy and precision it is a wash. Also the latest version of target scan is more forgiving of lighting requirements when scoring than previous versions. I can score targets on a white background under room lighting or if outdoors, I just hold the target up to the iPhone camera and I get very good results. To understand what I mean go to the developers youtube channel and watch the video. Congratulations to the developers.
Some other things that target scan does for me is provide statistics and the ability to maintain a shooters diary. The diary has become indispensable to me as a means to improve and is a lot easier to manage than a paper notebook. Scoring results, stats and diary are all stored in iPhone memory. If you have an iCloud account, your data is automatically uploaded there for archiving. Otherwise you can archive your data by mailing it to your email account.
There are some behaviors that need to be improved. One problem occurs when creating a diary entry. If you are typing and a phone call interrupts, then all that you have typed is lost when you return to the app (fortunately, the scoring information is intact). Also, when the app is updated to a newer version, all previous data is removed from your iPhone. If you are using iCloud then you can recover your data; if you have archived your data via email, then it remains there in your mail account. However, if you update and you have not archived via email or iCloud, then it appears you are out of luck. Fortunately, the developers are very good at listening to users and if history repeats, then there will be fixes in the next version coming soon.
Other reviews gripe about the cost of this app or the fact that the basic version does not have all the features turned on requiring more money in order to get certain targets, features, etc. To date I have spent less than $15US on this app to get it to do what I need to to do (I am a very avid 10 meter air pistol athlete). That is less than the cost of two tins of pellets. I think the app is certainly a good value if you are like me.
Other reviews claim that scanners or other equipment are required to make it work. These reviewers did not read the instruction annual or watch the video and are mistaken. All you need is the app and an iPhone. I have run the app on an iPhone 4 and iPhone 5c. it works equally well although the 5c processor crunches data much faster than that of the iPhone 4 giving nearly instantaneous results.
Summarizing, if you are interested in becoming a better target shooter then this is one thing I would recommend having.
<<From someone who shoots a lot, this app is indispensable. It scores your targets and enables one to keep a complete journal in your pocket. I use it every day. All of the poor reviews were written by people who didnt watch the instruction video or are unfamiliar with iPhone apps in general.
Best results are obtained using good quality paper targets and wad cutter pellets. A ragged hole is not going to be scored with the accuracy of a clean circle. My guess is that the app can distinguish two shots on top of each other with an offset of about a quarter of a millimeter. I can score a session of 60 shots in about a minute and images and stats are created instantly. Wow!
If you are using cheap paper or anything other than wad cutters then you wont be as enthusiastic about the app as I am. Otherwise get it.>>
