Update: severe bug with FaceID: if this app is the active app, and the phone goes to sleep, it goes into a state where it takes numerous (and I mean *numerous*) tries to swipe up to get the phone to wake. It just keeps showing a FaceID confirmation, but it stays on the lock screen. Anyone with an iPhone X, XS, or XR should beware. Presumably the new 2018 iPad Pro will also be affected.
I'm writing this from a parent's perspective. I imagine a coach would have a different view. The new app looks much better than the old, and acts much more like a modern iOS app. Neither old nor new versions make finding things easy. There are a *lot* of features, and it usually takes me a while to find what I'm looking for. Combining parent & coach apps seemed like a reasonable idea, until I saw all of the coach features cluttering up the screen. One feature I used a lot is either missing in the new app, or else is well-hidden: keying in the heat and lane assignments for events. I'd much rather have that info on my phone than carry around a paper meet program. The new app is slower than the old. It seems to load every page on-the-fly from the cloud, which is sluggish. On the meet entries display, 3-digit event numbers are truncated, which is a pretty severe problem. Touch ID is buggy - it often requires password entry, which kind of misses the point of Touch ID. OnDeck really needed a refresh, but this version is a swing and a miss.
