Troubleshooting common issues

Quick fixes first

Most snags clear up with one of three things: check your permissions, restart the app, or pull down to refresh. If something specific has you stuck, find it below — and if none of it helps, we're one email away.

Apple Health data isn't syncing

If weight, steps, or sleep from Apple Health aren't showing up, the usual culprit is a missing permission.

1. 1On your iPhone, open the Settings app.
2. 2Go to Privacy & Security → Health.
3. 3Tap DayByDay in the list.
4. 4Make sure every toggle you want synced is turned ON.
5. 5Open DayByDay and give it about 30 seconds to sync.
6. 6Still missing? In DayByDay, go to You → Health Sync and tap Sync now.
7. 7If it still hasn't appeared, restart the DayByDay app.
8. 8As a last resort, revoke all DayByDay permissions in Health settings and re-grant them — this forces a fresh sync.

I logged something but it's not showing up

Screens refresh when you open them, so a quick re-focus or pull-to-refresh usually does it.

1. 1Pull down on the screen to refresh.
2. 2Switch to another tab and back — that re-loads the latest data.
3. 3Check the date pill at the top of the screen; you may be viewing a different day than the one you logged.
4. 4If you logged while offline, give it a moment after you reconnect — it syncs automatically.
5. 5Still nothing? Close DayByDay completely and reopen it.

My weight trend line isn't showing

The smoothed trend needs a few data points before it can draw anything meaningful.

1. 1Make sure you have at least a few weigh-ins logged.
2. 2Check that they span several different calendar days — multiple entries on the same day count as one.
3. 3On the Weight screen, look at the chart range (1W / 1M / 6M / 1Y / All). A short window like 1W may sit outside your entries.
4. 4Switch to All to see your full history, then narrow back in.

My GLP-1 medication level looks wrong

The medication level is an estimate based on the drug's half-life. A few things can throw it off.

1. 1Open the GLP-1 screen and check your most recent dose log.
2. 2Confirm the correct medication is selected — different drugs have different half-lives.
3. 3Confirm the dose date is right. One day off can shift the estimate noticeably.
4. 4Check the dose amount.
5. 5If no dose has been logged in a while, the level decays toward zero — log any missed doses to bring it back.
6. 6Remember: it's a pharmacokinetic estimate, not a blood measurement. It won't match a lab result exactly.

Food search isn't working

The Nutrition tab's food Search, barcode scan, photo of plate, and nutrition-label scan are all part of DayByDay Plus. If you tap Search and it prompts you to upgrade, that's why.

1. 1Check your plan under You → DayByDay Plus/Core. Search and Scan It need Plus.
2. 2Enter manually is free on any plan — tap it on the Add Food sheet to log food without Plus.
3. 3If you're on Plus and search returns nothing, make sure you have an internet connection (the FatSecret database is online).
4. 4Try a simpler search term, then refine — e.g. "chicken breast" before "grilled chicken breast skinless".

My trial or subscription state looks off

If features you expect are locked (or you were charged unexpectedly), it's usually a billing-status sync that just needs a nudge.

1. 1Open You — your current plan (Free / Core / Plus, and trial status) is shown near the top.
2. 2If it looks wrong, tap into your plan and then Manage Subscription to refresh the billing status.
3. 3On iPhone, you can also confirm the subscription in App Store → your account → Subscriptions.
4. 4Restart the app to let the billing status re-sync.
5. 5Your 14-day trial unlocks the full Plus experience; when it ends, your account moves to the Free plan unless you subscribe — so check which plan is showing.
6. 6Still wrong after that? Email support@mydaybyday.app with the email on your account.

I can't log in

1. 1Try the Forgot password link on the login screen — enter your email and check your inbox for a reset link.
2. 2Make sure you're using the same email you signed up with.
3. 3If you signed up with Google or Apple, tap Continue with Google or Continue with Apple instead of entering a password — those accounts don't have a DayByDay password.
4. 4Check the email address for a typo.
5. 5Still locked out? Email support@mydaybyday.app with your account email and we'll sort it out.

My reminders aren't arriving

DayByDay can nudge you to log, celebrate milestones, send a weekly summary, and remind you about GLP-1 doses and refills. If they're not coming through, check both the app's settings and your phone's.

1. 1In DayByDay, open You → Notifications and confirm the reminders you want are turned on (Daily Reminder, Milestones, Weekly Summary, GLP-1 Reminders).
2. 2Check the delivery channel at the top — Both / Phone / In-app. "Phone" notifications need system permission; "In-app" only shows in the Notification Center.
3. 3On your iPhone, open Settings → Notifications → DayByDay and make sure Allow Notifications is on.
4. 4Check that Focus / Do Not Disturb isn't silencing them.
5. 5For refill and prior-auth reminders, confirm the dates are set under You → Pharmacy.

The app says I'm offline

DayByDay works offline — you can still log data with no connection. But if you see an offline banner when you expect to be connected, try this.

1. 1Confirm your phone has a working connection — open a webpage to check.
2. 2Switch between WiFi and mobile data.
3. 3Pull down on any screen to refresh.
4. 4Restart DayByDay.
5. 5Anything you logged while offline syncs automatically once a connection is detected — you don't need to do anything.

Charts aren't loading

1. 1On iPhone: close DayByDay completely and reopen it.
2. 2On web: refresh the page (Cmd+R on Mac, F5 on Windows).
3. 3Check your internet connection.
4. 4Try logging out and back in.
5. 5On web only: clear your browser cache.
6. 6If charts still won't load, email support@mydaybyday.app with a screenshot of the error.
