Get to know Peri-Lens.

Start with your own record.

Choose Start a new journal, then set up the symptoms you want to track and, if useful, your period pattern. Choose monthly or annual Plus and confirm with Apple or Google to start an eligible one-month store trial. Downloading or completing setup alone does not start access. You can change symptoms and tags later in More → Symptoms & tags. Local journaling with active store access, purchases, Restore purchases and eligible AI features do not require a Peri-Lens account. An optional account connection and a separate sync phrase are needed for encrypted backup and recovery.

Returning users can choose Restore a saved journal before setup. Sign in to the same account, enter the existing sync phrase once, then confirm Download and replace. This recovers the last uploaded journal; it does not start a new trial or restore subscription access. Recovery remains available after Plus ends.

The five bottom tabs are Today, Timeline, Insights, Trial, and More. Start with one short check-in on Today. Record only what you noticed. A day you skip is never treated as a day with no symptoms.

Where to find each feature.

AI weekly insights, AI appointment summaries and voice transcription require verified paid Plus for public customers; the public store trial does not include them. Authorized beta and temporary review access can include AI under the separate testing rules. All three require transfer consent, provider availability and the normal monthly allowances. Voice creates editable proposed fields, and a recording is sent only after you confirm. AI weekly reviews and local or AI appointment summary drafts remain unsaved until you review and explicitly save them.

Practical walkthroughs.

Screenshots show development app screens with sample data. Mobile-layout browser captures illustrate the screens; native permissions, recording, and store checkout may look different.

Build a seven-day observation record

Use a week to see how a small, honest record becomes easier to review.

View full-size screenshot

1. Open Today → Begin today’s check-in. Mark only the symptoms you experienced and add intensity, impact, sleep, bleeding, stress, or context when useful. If an entry is already saved, choose Review today’s check-in to reopen it.
2. Choose Review impact & context, add an optional note, and save. Repeat on days you want to record.
3. For a symptom that happens at a particular moment, use Today → Quick symptom episode to record its timing, duration, or count.
4. Open Timeline to revise an entry. Then visit Insights → Create local review to inspect the observed days and missing-day coverage.

Prepare for a care conversation

Make a patient-created discussion aid from the record you have. Creating a new brief requires active store-trial or Plus access.

View full-size screenshot

1. Go to More → Appointment brief and choose the visit date and record range.
2. Add one goal and one question, then write any context you want the clinician to understand.
3. Choose the sections to include and select Save and preview brief.
4. Read it for accuracy, then copy it or export a PDF to bring to the appointment. If you create a local structured summary or use optional AI wording, review the generated draft before choosing Save reviewed summary draft.

Compare one routine change

This is a descriptive personal trial, not a test of cause and effect. Starting a new trial requires active store-trial or Plus access.

View full-size screenshot

1. Open Trial → Create a personal trial → Create my own plan .
2. Choose one non-prescription routine change and one outcome already in your record, then Start baseline.
3. Keep your usual routine during the baseline and record check-ins when you can. Then select Start observation period.
4. Record adherence and other changes that may matter. Select Finish observation and compare to see the recorded differences and coverage.

Review a week and ask your history

Local reviews remain available with saved records. Public AI drafting requires paid Plus, consent, and available allowance.

View full-size screenshot

1. Open Insights → Create local review. Read the recorded facts, missing-day coverage, and suggested questions.
2. Add My reflection (editable) and choose Save my reflection when useful. Reopen a saved review in Saved review history.
3. Use Ask my history to choose a supported question about recorded information. Saved-record access includes questions through 30 days; longer calculated ranges require current trial or Plus access.
4. For optional AI wording, choose Draft with AI, review the disclosure, then Send and draft. Only the disclosed review facts and evidence are sent, not your full journal or private notes.
5. Read and edit the proposed wording. Choose Save reviewed AI draft only when you want to keep it; generating a draft does not save it automatically.

Turn a voice note into a reviewed check-in

For public customers, transcription requires paid Plus. It creates proposed fields for you to review, never a diagnosis or an automatically saved entry.

1. In More → Account & journal recovery, enable Allow AI summaries and voice transcription after reading the transfer disclosure.
2. Open Today’s check-in and choose Enable voice transcription, then Record a voice check-in. Allow microphone access if prompted.
3. Record up to one minute and choose Stop recording. Play recording to check it or Discard recording to remove it.
4. Choose Review disclosure and send, then confirm Send recording. Recording alone does not upload the audio.
5. Review and correct the proposed symptoms and context. Continue through Review impact & context and choose Complete today’s check-in, or Save changes when editing.
6. If audio cleanup fails, choose Retry audio cleanup before recording or sending another clip. Provider availability, consent, and monthly limits still apply.

Keep care steps and changes together

Record your own care information without turning the journal into treatment advice. New entries and edits need current logging access.

1. Open More → Care plan to record the care steps, goals, and questions you want to remember.
2. Open More → Treatment & change timeline → Record a change.
3. Set Date, Change type, Item category, Name, and What changed?. Optionally add a reason, effects you noticed, and a follow-up date.
4. Choose Save change. Review it alongside your observations without assuming it caused a symptom change.
5. Correct a saved entry when needed or use Delete entry and confirm to remove it.

Choose read-only health imports

Health imports are optional and require current trial or Plus access. Peri-Lens does not write records back to the health store.

1. Open More → Connected health on a supported native device.
2. Read the permission explanation and select only the measures you want to import.
3. Cycle data has a separate choice: enable Import menstrual flow records only if you want those records included.
4. Choose Request access and import, then review the device permission prompt and the result. Declining permission does not stop manual logging.
5. Change permissions in the device’s health settings; on Android, use Manage Health Connect access. The browser preview does not provide native health imports.

Back up and recover your journal

Cloud recovery uses an optional account and a separate sync passphrase. It is distinct from Restore purchases.

1. Open More → Account & journal recovery → Journal backup & restore and connect your optional account.
2. Set Device name and Sync passphrase; confirm the passphrase when creating recovery. Keep it safe: support cannot recover it.
3. With current trial or Plus access, choose Upload this device and confirm the reviewed upload. Signing in alone does not back up the journal.
4. Before replacing a device record, export anything newer that you want to keep. Choose Download latest remote data, enter the existing passphrase, review the replacement, and confirm Download and replace.
5. Returning users can also choose Restore a saved journal before setup. Recovery downloads remain available after Plus ends, but recover only the last uploaded revision.
6. Restore purchases recovers store access, not journal entries or passphrases. A JSON export is an archive, not an in-app restore file.

Set reminders, export, and manage privacy

Choose your controls and review what each action affects before sharing or deleting.

1. Open More → Account & journal recovery. Choose Discreet daily reminder and Reminder hour (0–23) if helpful.
2. Enable Device biometric / passcode app lock for an additional screen lock. This does not encrypt the local database.
3. Choose Export all data as JSON to keep an archive. Store it privately: exports can contain sensitive information.
4. Use Delete data from this device for device cleanup, or Delete account and all data for the account-deletion flow. Read the confirmation and deletion guide before proceeding; exported copies and store billing have separate controls.
5. Manage a subscription or cancel renewal through the Apple or Google account that purchased it. Removing the app or account does not cancel store billing.

Plans and access.

Eligible one-month store trial, confirmed at checkout. Plans renew unless canceled through store settings; cancel before trial renewal to avoid the next charge. Plus is planned at $4.99/month or $49.99/year in the US. New local logging requires verified trial or paid Plus access, or separately authorized beta/review access. Existing issued access keeps its original terms; no new account trial starts. Saved records, local weekly reviews, Ask My History through 30 days, saved briefs, existing personal trials, export, deletion and encrypted recovery remain accessible. Check current access in More → Plan & allowances. The public store trial includes logging, new personal trials and briefs, longer trends, health imports and encrypted backup after account/sync-phrase setup. Paid Plus adds AI transcription and AI drafting with separate transfer consent and monthly limits. See the full capability comparison.
