Exporting your data & health reports

Your data belongs to you

You can export everything in DayByDay, anytime, for free. No paywalls, no limits. If you ever want to leave, take your full history with you. If you want to share your progress with your doctor, there is a report for that too.

CSV export

CSV exports are available for every data type in DayByDay. The files open in any spreadsheet app (Excel, Google Sheets, Numbers) and can be imported into other health apps or analysis tools.

Available exports

• ✦Weight history — date, weight, body fat %, source (manual or synced), and notes
• ✦Sleep logs — date, total sleep, sleep stages (awake/REM/core/deep), SpO2 metrics, heart rate, and notes
• ✦GLP-1 dose history — date, time, medication name, dose, injection site, and notes
• ✦Body measurements — date and all tracked measurements (waist, chest, neck, clothing sizes)
• ✦Lab results — test date, A1c, glucose, cholesterol, triglycerides, and any other logged values

2. 2Tap the Export button (top right, or in the section menu).
3. 3Choose a date range if prompted, or export all data.
4. 4On mobile, your device will offer to share the file or save it. On web, the file downloads automatically.

2. 2Tap Generate PDF report.
3. 3Select your date range — choose a preset (last 30 days, last 90 days, last 6 months) or set custom dates.

How to share with your doctor

Once the PDF is on your device, you can share it like any other file — email it, AirDrop it, print it, or attach it to a patient portal message. Most providers are comfortable receiving PDF attachments through their secure messaging system.

Tips for getting the most out of your appointment

• ✦Generate the report 1–2 days before your appointment so you have time to review it yourself first.
• ✦Highlight specific questions: if your weight plateau started on a certain date, point to that on the chart.
• ✦Bring 90 days of data minimum — it shows enough of a trend for your provider to see patterns.
• ✦Ask your doctor to review your GLP-1 dose history alongside your weight trend — the connection is often clear.
• ✦If your A1c or glucose has changed, the labs section gives your provider the timeline at a glance.
