Help & FAQ

HypoMe is a personal experiment tracker. You pick something you want to change about your life (sleep, focus, cooking satisfaction, energy, anything you can measure daily), run a short trial with daily check-ins, and HypoMe gives you a plain-language before-and-after verdict backed by real statistics.

An experiment has three parts: a hypothesis (“does daily meditation reduce stress?”), an intervention (the change you’re testing), and an outcome (what you measure). HypoMe compares a baseline period (normal life) against an intervention period (the change) and tells you whether the difference is meaningful.

Most experiments run 3–4 weeks total: a 1-week baseline plus a 2–3 week intervention is a good default. Shorter runs give noisier results; longer runs reveal subtler effects but demand more consistency. You can pause and resume any experiment if life gets in the way.

Free accounts can have one in-progress experiment at a time. Premium removes that cap so you can run several in parallel. Running too many overlapping experiments makes it harder to tell which change is responsible for a result — HypoMe will warn you when you’re about to start a fourth concurrent experiment.

HypoMe uses AI for three things:

• AI Experiment Designer — describe a goal in plain language, get a ready-to-run experiment (hypothesis, intervention, outcome, duration) you can start with one tap.
• AI Results Interpreter — after an experiment finishes, AI writes a plain-English interpretation of what the numbers mean in context.
• Next-Experiment Suggestions — based on what you’ve already tried, AI suggests follow-up experiments to deepen or refine the finding.

When you invoke an AI feature, HypoMe sends the relevant experiment metadata and entries (titles, intervention descriptions, outcome values, dates, notes) to Anthropic’s Claude API. We do not send your email, name, or Apple ID. See our Privacy Policy for full detail.

We don’t persist raw prompts or raw responses on our servers after the request completes. We keep a short metadata log (model, token counts, duration, error type, and a one-way hash of your internal user ID) for 60 days to audit cost and prevent abuse. Anthropic’s handling of data sent to their API is governed by their own terms at anthropic.com/legal.

Three possible reasons: (1) you hit a rate limit (free accounts: 3 AI designs per month; all accounts: 5 AI requests per hour); (2) we temporarily disabled AI globally or for your account while investigating an issue; (3) the upstream model returned an error. In all three cases the app will tell you which case applies and when you can try again.

Free accounts get 3 AI-designed experiments per month. Premium removes that monthly cap (the 5-per-hour throttle still applies, to both free and Premium, to keep costs predictable). Results Interpreter and Next-Experiment Suggestions are Premium-only.

Current pricing, trial terms, and regional availability are shown in the App Store before you purchase. Subscriptions are billed through Apple and may vary by region.

Eligible users get a free trial on the annual plan. Trial eligibility is determined by Apple and generally applies to users who haven’t previously redeemed a HypoMe trial. The trial converts to a paid subscription at the end of the trial period unless you cancel beforehand.

Cancel any time in your Apple ID Account Settings (apps.apple.com/account/subscriptions or Settings › [your name] › Subscriptions on iOS). Cancellation takes effect at the end of the current billing period — you keep Premium access until then.

Open HypoMe › Settings › Restore Purchases. If you’re signed into the same Apple ID that made the purchase, entitlement is restored within a few seconds.

Refunds are processed by Apple, not HypoMe. Request a refund at reportaproblem.apple.com.

No. Apple subscriptions are managed by Apple, not by us — deleting your HypoMe account does not cancel billing. Cancel your subscription in your Apple ID settings before deleting your account (HypoMe will warn you if you try to delete with an active subscription).

Only the four metrics HypoMe offers as experiment outcomes: Sleep Duration, Daily Steps, Heart Rate Variability (HRV), and Active Calories. You grant permission per metric, only if you pick a HealthKit-backed outcome. HypoMe never reads any other health data.

Four common reasons: (1) permission is off — open iOS Settings › Health › Data Access & Devices › HypoMe and confirm read access for the metric; (2) the source device (Apple Watch, iPhone, third-party app) hasn’t synced yet; (3) the metric type doesn’t exist in your Health app yet (HRV, for example, requires an Apple Watch); (4) the baseline period starts today — Apple Health data for today isn’t finalized until the day ends.

iOS Settings › Health › Data Access & Devices › HypoMe › toggle off any metric, or “Turn Off All” for all of them. Existing experiments that relied on that metric will fall back to self-reported check-ins.

Nothing — Apple Health data lives on your device, not on our servers. HypoMe only stores the resulting numeric outcome values for your experiment days (e.g. “8.2 hours slept on 2026-04-14”), the same as if you had logged them manually. Those stored values are deleted when you delete your account.

Premium subscribers can export any completed experiment as CSV or JSON from the results screen. Free accounts can’t export directly — upgrade to Premium, or email support@hypome.com to request a copy.

Open HypoMe › Settings › Delete Account. This permanently removes your experiments, entries, settings, and account credentials. The process is irreversible. A small amount of data persists after deletion (server logs, crash reports, Apple’s own transaction records) — see § 4 of our Privacy Policy for the exact list.

If you’ve opted into Anonymous Sharing, HypoMe has collected aggregate stats (means, effect size, adherence rate) from your completed experiments — no user identifier, no intervention text, no daily data. You can revoke previously shared contributions any time from Settings. Community contributions aren’t linked to your account and aren’t deleted automatically on account delete — revoke them first if you want them removed.
