Aside from the app not having more details on each killer within it, it's worth the buy. Also it does offer a more info link to get into each killers wiki. I've found some that I hadn't heard of before too, which is nice since I thought I knew about all of them ;)

Basically sends you to the information you're looking for. It's a worth the $$ app. If you enjoy this type of thing.. Which you do.

When people see a serial killer application they often think that the creator must be trying to capitalize on what we all know is a taboo subject - but this is not the case with this particular application. What you will find is one of the most broadly researched (profiles over 500 serial personalities from around the world) and the application's designer took the time to report facts, details and a recent pictures in a very accurate and respectful way.Many of the other serial killer applications try to lure you in with blood dripping and shock, but there is no substance behind them. What you get with this app are various ways to search for cases. Even if you don't know the correct spelling, you can narrow your search by sex (male or female), by country, by moniker or by many other aspects of the crime. There is even a section to show if a particular case has been adapted into a television episode or film.Once you make this purchase you will be surprised at the level of detailed information behind each of these infamous cases. What's more, you will learn how America is far from the only country with these individuals and that white males are far from the only perpetrators. The application is respectful and mindful that human lives were taken. The app creator used the proper term "victims" and did not glorify the fact that innocent sons, daughters, husbands and wives were taken by these men and women. Instead of saying (like all the other apps do) KILLS or total number of kills - this app calls the lives were taken just what they are - victims. Innocent victims. These were lives that were taken and that is important to remember.So, while the subject remains taboo and upsetting for many, The Serial Killer Murder Library handles all of these facets in a most responsible way. If I could provide more stars, I would. I fully support and endorse this application as a forensic consultant and criminal profiler - and the co-author of The Diary of the D.C. Sniper.

Best app for my phone that I have ever bought. Not only can you learn but you can connect the the owners website and read updates that you don't see on tv. I think it's amazing.
