Sleep is about more than just measuring the time you were asleep. The amount of time spent in N3/4 (Deep Sleep) and REM sleep is very important.
The author is using sleep cycle on his phone, which is not a good method of tracking sleep cycles. He says "their ability to wake me in “non-deep” sleep pretty spot on" - you're not in deep sleep in the morning anyway, or very unlikely. So any "app" has a good chance of waking you from REM or N1/2.
We've been building a headband which monitors your sleep state, and uses sound to improve your sleep performance. Literally, improving the neurological function of your brain while you sleep.
We're currently working on improving the fit and comfort before finalizing industrial design. You can find out more, and join the waitlist at https://soundmind.co

I used one of our early prototypes to win the Sleep World Championships (https://soundmind.co/blog/neurohacking-the-world-sleep-champ...).
