Sleep Habits: N of 1

Find what actually improves your sleep. The internet says what improves sleep in general. A tracker says how you slept. Sleep Habits: N of 1 answers the question that matters: what works for YOU? Pick a research-backed sleep experiment — caffeine cutoff, morning daylight, a consistent wake time, screen-free evenings and more. Log a few baseline nights, then make the change. A 15-second morning check-in is all it takes. When the experiment ends, your own data delivers the verdict: HELPED · NO CLEAR EFFECT · MAY HAVE MADE IT WORSE No wishful thinking. "No clear effect" is a real finding too — it saves you from running habits that do nothing for you. WHAT YOU GET • 12 research-backed sleep experiments, each grounded in published studies • Honest recommendations — the app will even tell you when an experiment is probably NOT right for your situation • Baseline → experiment design, so you compare against your own normal • A 15-second morning check-in: sleep quality, restedness, time to fall asleep • A clear result page — plain language, no made-up percentages • Retest any result to see if the effect repeats • Your personal Sleep Playbook: what helped, what didn't, kept for good • A Lock Screen widget with your current experiment, always at a glance • Custom experiments for anything else you want to test NO STREAKS. NO GUILT. A missed day is a data point, not a broken chain. Reminders are quiet and optional. Nothing nags forever — every experiment has an end date. PRIVATE BY DESIGN Your data stays on your device. No account. No cloud. FREE & PRO Your first experiment is free — recommendation, baseline, result and playbook included. Lab Pro is for continuing: run as many experiments as you want (one honest test at a time), retest your results, keep your full archive, and export everything as Markdown/CSV. Your sleep is the lab.
