  1. Sorry I went MIA for a while. I'll give an update here about what's been going on with the app and try to answer some of the questions that were brought up. First things first, during the Apple's app review process they determined that the app's use of the workout and heart rate features were not a valid use case because the app isn't primarily used for fitness. I tried to make my case but they ultimately decided those features needed to be removed. This means several features on the watch have been lost including inversions, hangtime, altitude and heart rate. I hope there is a way to brin
  2. Ah thanks for letting me know, I'll note this in the app and on the App Store listing. Apple's documentation wasn't very clear on this, it does appear that you'll need an iPhone 7 or newer to record rides on an iPhone. For those with older phones you could still pair an Apple Watch, if you have one, and use it that way.
  3. Yes only iPhone at the moment. An Android version would probably be possible but I don't have plans to work on that in the short term. The 1 g force of gravity is included in this calculation so 3.6 is the correct value. Acrobat, the clone of Manta at Nagashima Spa Land, lists the max g force of their ride at 4.09 g. So it's close but not quite the same. There are many variables that could account for discrepancies like this, such as what seat you're in (I was near the back on this ride, I think the middle might produce higher forces?), how fast the ride is running, rattle of the ride
  4. Ha yes, that was definitely a consideration when deciding to build the app for Apple Watch. I encourage everyone to follow the rules!
  5. Hi all. I wanted to share an app I’ve been working on for the past year or so with Coastin Eric that I hope coaster enthusiasts like ourselves might find interesting. For several years I’ve found myself wanting more when it comes to thrill ride statistics. Sure we’ve got standard ones like height, length, speed, and if we’re lucky max g force. As a lover of airtime I wanted to know more than just the max g force. I remembered playing games like RollerCoaster Tycoon seeing stats like max negative g’s, total airtime, and a graph of the forces throughout the whole ride. I wanted these sta
  6. I visited Discovery Kingdom today. Here's a quick photo update featuring The Joker's construction and some other stuff they're working on around the park. Some Joker track. Coaster parts! Track in the parking lot, very Six Flags. A nice view at the entrance of the park. Lots of rides were closed today. The Joker's first drop Transition after the first drop into the first inversion. View of Joker's first inversion from outside the park's entrance. Joker's first inversion from another angle. The trick track before the lift. Overview of Joker's construction so
  7. I've been wondering about this, specifically how orientation should affect calculated forces. As an example, a barrel roll taken at a slow speed. (Think Tempesto, or Hydra) As you go through the inversion you're always experiencing 1 G but the angle changes, so you'll take 1 G of lateral force when you're body is parallel to the ground. When you're upside down you're experiencing -1 G. So then do we consider a ride that just holds you upside down to be providing negative Gs?
  8. Great Adventure some weekend in September. Then Disney World and Universal the first week of October.
