Her Sleep Debt Was 26.5 Hours — Scheduling Her Day Around Her Energy Cut It Nearly in Half
4 min read · RealCase summary
A reviewer used the Rise sleep app — rated 4.7 stars from more than 37,000 reviews, priced at $69.99 a year with a 7-day free trial — to align her schedule with its personalized energy-peak predictions: tackling demanding work during an 8:15-11:30 a.m. peak, resting through a 1:37-3:41 p.m. dip, exercising during a 5-8:15 p.m. surge, and starting her wind-down at 8:34 p.m.
Over a few weeks of use, her sleep debt fell from an initial 26.5 hours to 16.7 hours, a reduction of 9.8 hours, in a review published May 16, 2025.
"Living by these peaks and valleys has not only helped me feel less sleepy during the day, but I'm also slowly chipping away at my sleep debt," she wrote, rating the app 4.5 out of 5 overall.
Key takeaways
