HypoMe: Self-Experiments

Most tracking never ends. HypoMe runs one question for a set number of days, finishes with a real answer, then helps you keep what worked.

Most tracking never ends. You log, and log, and one day you stop — no closer to knowing whether it worked. HypoMe is built the other way round: one question, a set number of days, an answer at the end.

Does cutting caffeine after 2pm actually improve YOUR sleep? Describe the goal in plain English and the AI Experiment Designer turns it into a full experiment — intervention, outcome, baseline, run length. Record a few ordinary days as a baseline, then make the change and check in for about ten seconds a day.

On the date you set, HypoMe compares baseline to change and tells you what happened in one sentence. You add your own takeaway beside the statistical one, and keep what worked as a practice with a reminder and a review date. The check-in streak tracks how consistently you logged — it is not the goal, and the run ends either way.

You can run a full experiment without an account. An account adds sync across iPhone and the web, publishing, and Premium.

DESIGNS THAT HOLD UP

• Crossover (A/B/A) designs that test whether an effect really repeats (Premium).
• Blinded runs — HypoMe seals which container is which until the end (Premium).
• Two to five outcomes at once, and custom scales in your own units (Premium).
• Confound tagging — flag travel, illness, or disrupted weeks so they don't muddy the data.
• Apple Health — pick a HealthKit metric (sleep, steps, HRV, active calories) as your outcome.

WHAT YOU GET AT THE END

• A plain-English verdict: direction, magnitude, effect size, and trend, with Cohen's d and standard deviation behind it (Premium).
• "Inconclusive" treated as a real result, with an explanation of why.
• AI Results Interpreter (Premium) — phase-by-phase breakdown, confound patterns, adherence impact, what next.
• A findings ledger where every completed run becomes something you know.
• Publish the method behind a result so someone else can run it, or fork theirs.

YOUR DATA, YOUR CONTROL

• Sign in with email or Apple. No social graph, no public profile, no advertising.
• Encrypted in transit. Data between your device and our servers travels over TLS.
• Apple Health is read on-device with your explicit consent for the metrics you pick. Only the resulting outcome value for each experiment day is stored with your entries — never the raw Apple Health data as a separate payload.
• Anonymous community contributions are opt-in. When enabled, only aggregate stats are added to the public community table — no user ID, no experiment ID, no intervention text, no hypothesis, no raw entries. Opt out or revoke past contributions anytime in Settings.
• Export your experiments, entries, and settings anytime as JSON from Settings.
• Full account deletion in Settings — permanently removes your account and associated data.
• Read the full Privacy Policy at hypome.com/privacy.

PREMIUM

• $4.99/month or $29.99/year — first month free on annual. Cancel anytime in Settings.
• Free tier: 1 experiment at a time, run all the way to a verdict; 3 AI designs/month. Nothing about finishing an experiment is paywalled.

Built for people who want to know what actually works for them. No woo, no medical claims, no mystery.
