Finding your settings
Most settings live in the Settings screen, accessible from the bottom tab bar or sidebar depending on your device. Dashboard-specific settings (which cards show, card order) are in a separate Dashboard Settings modal — tap the gear icon at the top of the Dashboard tab to open it.
Your profile
Your profile settings are the foundation of everything DayByDay calculates. Make sure these are accurate for the best results.
Display name
This is your name as it appears in the app. It is not public — only you see it.
Email address
The email address you signed up with. To change it, tap Email and follow the verification steps. You will receive a confirmation email to your new address before the change takes effect.
Profile photo
Optional. Tap the avatar circle to pick a photo from your camera roll. Your photo is stored securely and only visible to you.
Goal weight
The target weight you are working toward. DayByDay uses this to calculate your progress percentage and to predict when you might reach it based on your trend. You can update it anytime — there is no penalty for adjusting your goal.
Target date
An optional date by which you want to reach your goal weight. If set, DayByDay will show you the pace required to hit it. Leave it blank if you prefer to focus on the trend rather than a deadline.
Preferred units
Choose lbs or kg. DayByDay converts all your data automatically when you switch — you won't lose any history. Height is stored separately and can be set in inches or centimeters.
Dashboard settings
How to open Dashboard settings
Tap the gear icon at the top right of the Dashboard tab. This opens a separate modal just for dashboard customization.
Which cards are shown
You can turn individual dashboard cards on or off. Cards include: Goal progress, Today's Pulse, Momentum streak, Coach Notes, Weight trend, GLP-1 level, Sleep summary, Exercise summary, and Upcoming milestones. Hide anything that is not relevant to your journey.
Card order
Hold and drag the handle on any card row to reorder them. Your dashboard is yours — put the things that matter most at the top.
Theme
Light mode
The default look — warm white background with coral accents. Easy to read in any lighting.
Dark mode
A deep, dark interface that is easier on your eyes at night. DayByDay respects your system setting automatically, or you can lock it to dark mode from Settings → Theme.
Journey Mode
Journey Mode is a premium sunset theme that turns your check-ins into a moment you actually look forward to. The interface shifts to warm amber, orange, and deep purple tones — like golden hour, built into your health app. Switch it on from Settings → Theme → Journey Mode.
Premium — Journey Mode
The sunset theme that makes checking in feel like a reward. Available with a DayByDay premium subscription.
Health sync
Found in Settings → Health sync. This section controls which data sources are connected and what data DayByDay reads from them.
Apple Health permissions
Tap Manage Apple Health permissions to open the system permissions sheet. You can grant or revoke access to individual data types: weight, steps, sleep, workouts, and heart rate.
What data syncs
DayByDay reads weight, steps, sleep stages, active energy, exercise minutes, and resting heart rate from Apple Health. It never writes data back to Apple Health.
Sync frequency
Apple Health syncs automatically every time you open the app. You can also tap Sync now to pull the latest data immediately.
O2 Ring status
Shows whether your Wellue/Viatom O2Ring data has been imported. O2Ring data comes in via CSV import from the O2Ring app — it does not sync automatically.
Notifications
Weigh-in reminders
Set a daily reminder to log your weight. You can choose the time (most people choose first thing in the morning) and toggle it on or off. Go to Settings → Notifications → Weigh-in reminder.
GLP-1 dose reminders
DayByDay can remind you when your next GLP-1 dose is due, based on your injection schedule. Set it up in Settings → Notifications → Dose reminder. The reminder triggers at the time you specify on your scheduled dose day.
Enabling notifications
If you previously denied notification permissions, iOS will not prompt you again automatically. Go to your iPhone's Settings app → DayByDay → Notifications and turn them on from there.
Data & privacy
Export your data
You can export any of your data as a CSV file at any time — weight history, sleep logs, GLP-1 doses, measurements, and lab results. Exports are free and unlimited. Go to Settings → Data & privacy → Export data or use the export button inside each section.
Delete your account
To permanently delete your account and all associated data, go to Settings → Data & privacy → Delete my account. This action is permanent and cannot be undone. Your data will be deleted from our servers within 30 days.
Subscription
Go to Settings → Subscription to see your current plan, trial status, and renewal date.
View your plan
This screen shows whether you are on a free trial, monthly plan ($5.99/month), or annual plan ($59.99/year). It also shows your next renewal date.
Upgrade to premium
Tap Upgrade to see the available plans and start your subscription. Payment is handled securely through the App Store.
Manage through the App Store
To cancel or change your subscription, go to your iPhone's Settings app → [your name] → Subscriptions → DayByDay. Apple controls all subscription billing — DayByDay cannot process refunds or cancellations directly.
Support
Contact support
Tap Settings → Support → Contact us to open a support request. Include as much detail as you can — what you were doing, what you expected to happen, and what actually happened. We typically respond within 1 business day.
