Keep a short, flexible record of the details that matter to you.
Private perimenopause observations
Peri-Lens is a local-first perimenopause app for recording symptoms, reviewing your observations, and preparing for healthcare appointments. Keep a private record for a clearer conversation, with missing days left unknown.

Keep a short, flexible record of the details that matter to you.
Review descriptive patterns with the missing days left honestly unknown.
Shape your observations into a focused brief for the care conversation.
A record that fits real days
A daily check-in can include symptoms, intensity, impact, bleeding, sleep, stress, context, and an optional note. Quick symptom episodes capture a moment without turning it into a full form.
Track symptoms such as hot flashes, night sweats, sleep disruption, mood changes, and brain fog, alongside your own context and notes.

Traceable, not predictive
Insights summarize observed days only. Coverage stays visible, questions are answered from your local history, and every highlight is grounded in the record behind it.
Peri-Lens describes your entries. It does not diagnose, predict, or infer a cause.

Built for the first release
Focused tools for keeping a private record, exploring it carefully, and preparing for care. Compare saved-record access, the store trial, and paid Plus below.
Record symptoms, bleeding, sleep, stress, context, and notes without turning an unrecorded day into a zero.
Capture a moment as it happens, then keep it connected to the same private timeline.
Review observed-day trends, a local weekly review, and bounded Ask My History questions. Missing days stay unknown, and you can inspect the entries behind each result.
Choose an available clinician-reviewed template or your own routine plan, then compare observed periods without claiming that the change caused the result.
Choose goals and questions, save a brief and snapshot, then review and copy or export it for a clinician conversation.
Optionally read selected sleep, activity, and cycle measures from Apple Health or Health Connect.
Optionally back up an encrypted journal with your account and a separate sync phrase. Restore the last uploaded copy with explicit Download and replace consent.
Use reminders and app lock, export your complete record, or separately delete device data and account data.
Keep a care plan, treatment and change timeline, and versioned clinician-reviewed learning cards beside your observations.
Paid Plus includes optional AI appointment-summary and weekly-insight drafts, plus voice transcription for check-ins. Review the wording and fields before saving; each transfer requires your consent.
Planned US pricing
Peri-Lens is not publicly available yet. These are planned US prices; the stores will show final local prices, eligibility, and renewal terms at launch.
Start a new journal, complete setup, then choose monthly or annual Plus and confirm with Apple or Google. An eligible one-month store trial starts only after that confirmation. Journal tools and encrypted backup are included; AI features unlock when your paid subscription begins. No Peri-Lens account is needed for purchase or local journaling.
Monthly and annual subscriptions include the same Plus features: continued logging, longer trends, personal trials, appointment briefs, optional health imports and encrypted backup. Verified paid Plus also unlocks AI appointment summaries, weekly insights and voice transcription within the monthly allowances below.
Always available without a subscription: Your saved health records, recent descriptive trends, reminders, app lock, export, and deletion controls remain available after access ends. New entries and edits require active trial or Plus access.
Compare what remains available without Plus with the eligible store trial and paid Plus. On a small screen, scroll the chart sideways to see every column.

Downloading the app or completing setup does not start a trial. Apple or Google confirms offer eligibility, localized price and the future monthly or annual charge before checkout. New logging begins after verified access; canceled or unsuccessful checkout grants no new trial. Plans renew unless canceled through store settings; cancel before the trial renews to avoid the next charge. A calendar month is determined by the store. If you are not eligible for the offer, the store shows the paid terms before you confirm.
AI features are not included in the public store trial. Paid Plus allowances reset each UTC calendar month: 50 successful AI drafts shared across appointment summaries and weekly insights, and 60 transcription minutes. Voice clips can be up to one minute; each successful transcription uses one whole minute. AI and audio transfers require separate consent. Local summaries and manual notes remain available during the trial.
Returning to an existing journal? Choose Restore a saved journal before setup, sign in to the same account, enter your sync phrase once, then confirm Download and replace. This recovers your last uploaded journal and remains available after Plus ends. Restore purchases checks existing subscription access; it does not restore journal contents or start a new free month.
Private by default
No Peri-Lens account is required for local journaling with active store access, purchase or Restore purchases. An optional account and separate sync phrase are needed for encrypted journal backup and recovery. Sign-in alone never uploads or replaces your journal. Optional AI and voice send only the disclosed facts or confirmed audio with your consent; you review the result before saving.
Connected health is read-only. You choose the measures and can keep cycle access separate.
Peri-Lens does not diagnose, recommend treatment, interpret tests, or monitor emergencies.
