How can we help?

When you first open Presli, the onboarding flow will prompt you to enter a name and configure basic settings. You can always add more profiles later from the Profiles section on the Home tab.

Yes! You can add multiple profiles — useful for tracking yourself and family members like a spouse or elderly parent. Switch between profiles from the Home tab. With Presli Premium you can add unlimited profiles.

No account is required, and no internet connection is needed for any core feature. All your data is stored locally on your device. The only time the app needs internet is when processing a Premium upgrade through the App Store or Google Play.

Blood pressure is always in mmHg. Weight can be logged in kilograms or pounds — you can change this in Settings. Caffeine is tracked in mg. Sleep is tracked in hours.

Tap the + button on the Home tab, then select Blood Pressure. Enter your systolic and diastolic values. The pulse field is optional. The app will automatically classify your reading (Normal, Elevated, Stage 1, Stage 2) and save it with a timestamp.

Yes. When logging any reading, tap the date/time field to change it to any date and time you need. This is useful when you forgot to log something earlier in the day.

On the Home tab, scroll to the reading you want to edit and swipe left to reveal the edit and delete options. You can also find readings in the Calendar tab to edit from there.

Tap the + button on the Home tab and select the type of reading you want to add. Each vital type has its own quick-entry sheet. You can also log them from the quick-action buttons on the dashboard.

Custom Metrics (a Premium feature) let you track any health value not covered by the built-in vitals — for example, blood glucose, oxygen saturation, or any number your doctor wants you to monitor. You define the name and unit, and then log values just like any other reading.

Go to the Meds tab and tap the + button. Enter the medication name, dose, frequency, and start date. You can also add optional notes. The medication will appear in your list and in PDF reports.

On the Meds tab, tap the Log Dose button next to a medication. The app records the time and adds it to your dose history. You can view past doses by expanding the medication card.

Yes. In Settings, scroll to the Reminders section and enable medication reminders. You can set a daily reminder time for each medication, and the app will send a notification at that time.

PDF export requires Presli Premium. Once unlocked, go to the Stats tab and tap the Export button, or find the export option in Settings. You can choose a date range and the PDF will include charts, rolling averages, and your medication list.

Yes. If your device language is set to Spanish, the PDF will be generated entirely in Spanish — including all section headers, chart labels, day names, and medical content. Switch your device language in your device's Settings app.

After generating the PDF, your device's share sheet opens automatically. You can email it, share it via Messages, save it to Files, print it, or send it through any other app on your device.

Premium unlocks five features:

• PDF Reports — full doctor-ready reports with charts, averages, and medication history

• Custom Themes — dozens of color schemes to personalize the app

• Custom Metrics — track any health value beyond the built-in vitals

• Unlimited Profiles — add as many profiles as you need

• Home Screen Widget — see your latest BP reading without opening the app

No. Presli Premium is a one-time purchase for $9.99. You pay once and own it forever, including all future updates. There is no recurring charge.

Go to Settings → Restore Purchases. Make sure you're signed in with the same Apple ID or Google account you used when you originally purchased Premium. The restore will complete automatically.

Try the Restore Purchases option in Settings. If that doesn't work, please contact us with your order number from the App Store or Google Play and we'll resolve it for you.

Yes, completely. All your health data is stored only on your device. We have no servers, no accounts, and no way to see your data. See our Privacy Policy for full details.

Go to Settings → Backup & Restore to export a backup file. Save it to iCloud Drive, Google Drive, or any other location. To restore, tap Restore Backup and select the file. Your data is included in your device's standard system backup (iCloud or Google Backup) if you have that enabled.

All your locally stored data is permanently deleted when you uninstall the app. We recommend exporting a backup or PDF report before uninstalling if you want to keep a record.

No. Presli contains no analytics SDKs, no advertising networks, no crash reporting services, and no tracking tools of any kind. We collect zero usage or behavioral data.

Go to Settings and scroll to the Reminders section. You can enable a daily blood pressure logging reminder, a daily weight reminder, and medication reminders — each with its own time setting.

Make sure notifications are enabled for Presli in your device's system Settings app. On iOS, go to Settings → Presli → Notifications. On Android, go to Settings → Apps → Presli → Notifications. On Android 12+, you may also need to disable battery optimization for the app.
