A lot of fun! I originally downloaded this app for my grandson, but I got around to using it also. For my aerobic routines, for example, I set it to a repeat cycle every 30 seconds (two cycles exercise one cycle rest). I like the mental workout for pattern recognition by changing the symbols regularly. I've re-watched the movies just so I can read the countdown on the Predator's detonator! On my phone, I use it at work for reminders for specific chores at set times. There's about a five second delay before the countdown starts again, instead of an immediate repeat, otherwise I would have given it five stars. That's just being nit picky, though. I'm satisfied the way it is.

I've looked long and hard for a clock that stimulates the predator number system ever since I saw it in the original movie. This app does what it claims, and does it flawlessly with some good extra features like the stopwatch and alarm parts. It also comes with the ability to change to other systems of symbol (i.e. Arabic) which is pretty cool, clever and entertaining. I also got a the table that actually teaches me to read these predator time back to normal time, wow -> can't be any better! it's the best.

I use it all the time in meetings, never paying attention to it, but I see folks looking at the screen. I can tell which ones know what it is by their quick smile. Others just think its some new kind of computer they don't know or understand. I used to think it locked up and crashed, but it was because I had it locked it on the side. It likes to be started in portrait mode and configured. Runs great.WARNING. If the alarm goes of on a plane, people freak.

The clock and the tones are awesome! I would change my review to five stars if the developers figure out a way to make it my lock screen. The issue is that the clock turns off whenever my phone turns off and if I set my phone to stay on longer it would also stay unlocked. Not a great security practice. I would also like to recommend that instead of the black backdrop could we see images of the predator spaceship walls surging? Holla

This is a awesome app, but the only problem I’m having is enabling my alarm clock. I set the alarm for a certain time and go to the next menu to enable the alarm and it kicks me out of the whole app. Everything else works just fine. Some small bug fixes are in need of some additional attention, other than this it is an excellent way to keep track of time!

Put it on my phone and people look on in amazement every time they ask me the time. This is the cleanest predator clock app on the app store right now (actually they are quite rare lol). I particularly love the count down feature backed by the exploration sound, it's so fantastic just like in the movie. So after these years I know the Predator number system!
