This is awesome. Just yesterday I was doing a 7-minute workout in my room, just because I was waiting for dinner to finish heating up. The main problem is that the standard timer app on iOS only acts as a stopwatch...so the final ten seconds of each interval, I'm watching the clock so that I can hit "Lap" and move on...this is awkward when I'm also wearing headphones to listen to music. What would be ideal for me is…

check this out, tons of HIIT timers out there. i grew up wrestling and used to use a physical device called a gymboss which was awesome at the time. they have now made Android and iOS apps

I know exactly what you mean- I use this free app called 30/30 on my iPhone (https://itunes.apple.com/us/app/30-30/id505863977?mt=8), and it works great for a productivity cycle, e.g. rotating between focusing and doing something relaxing. I imagine it would be pretty good for workouts as well.

Earlier quoted context omitted.

I've read a bit about high intensity training (tabata, hiit, crossfit, etc.) and there seems to be quite a good bit of evidence supporting their utility. The 7-minute workout may well fit in that same category. However, as an old fogie, I recall a craze back in the 70s and 80s called 5BX, which stood for 5 basic exercises, created by Swedish aircrew iirc. The reason I recalled it is the mention of rapid-style jumping…

According to the Wikipedia entry, the harm from 5BX was caused by the situp. Replace with crunches and you're good.

Yes, that's a good catch. I think it was only late into the '80s that full sit-ups began to be deprecated. I did notice the 7-minute work out emphasizes abdominal crouches which is good. However, 5BX did also cause knee and elbow problems (thanks to the crouching jumping jacks and clap happy push-ups). I'd say watch out for routines involving jerky movements.
