Frequently Asked Questions

Yes — NourAIsh is now PureLog^™. Same app, same team, same data, with a sharper name and our biggest update yet.

If you already have NourAIsh installed, it simply becomes PureLog the next time your apps update — there's nothing you need to do, and all your entries, recipes, vitals, and settings carry over automatically.

Sage is PureLog's built-in nutrition assistant. Chat with Sage to log meals in plain language ("two eggs on toast and a coffee"), brainstorm what to make, and ask nutrition questions tailored to your goals.

Sage is a PureLog Premium feature.

Memory is where Sage remembers what matters about you — your tastes, dislikes, allergies, kitchen, and goals — so its suggestions and recaps feel personal instead of generic.

You can see and edit everything it knows, anytime — nothing is hidden, and it all stays on your device and travels with your backup. Memory is a PureLog Premium feature.

The Gut Check is a short, friendly recap of how yesterday went against your goals, written each morning by Sage from your meals, limits, and activity. It celebrates the wins and kindly flags anything that ran high — and it even names the food behind the number (e.g. "mostly from the soy-glazed chicken"). It's a PureLog Premium feature.

On iPhone, PureLog syncs with Apple Health. Turn on nutrition sharing in Settings > Apple Health, and the meals you log in PureLog flow into Apple Health.

From there, other apps that read Apple Health — like Google Health (formerly Fitbit) — pick up your data automatically. So log a meal in PureLog and see it in Google Health, no extra setup required.

2. Tap Backup & Restore
3. Tap Create Backup

Backup files are named PureLog-[date]-[id].purelogpack for easy identification.

Yes! PureLog can remind you to backup your data:

1. Go to Settings > Backup & Restore
2. Under Reminders, select your preferred frequency:
   • Never
   • Weekly
   • Monthly

You can also see when your last backup was created in this section.

A PureLog backup includes:

• Weight entries
• Blood pressure entries
• User profile and settings

The backup file shows you exactly how many entries of each type are included before you restore.

To enable meal reminders:

1. Go to Settings > Notifications
2. Toggle on Meal Reminders
3. Set your preferred times for:
   • Breakfast
   • Lunch
   • Dinner
4. Select which days of the week you want reminders

This is useful if you have a different routine on weekends or certain days.

If you're not receiving notifications:

1. Check that notifications are enabled in Settings > Notifications
2. Look at the Notification Permission status at the top of the screen
3. If it shows "Disabled," tap Settings to open iOS Settings and enable notifications for PureLog
4. Use the Send Test Notification button to verify notifications are working

PureLog offers three interruption levels:

• Passive - Appears silently in Notification Center only
• Active - Standard notification with sound and banner
• Time Sensitive - Breaks through Focus modes (except Sleep)

Choose "Time Sensitive" if you tend to miss notifications due to Focus modes.

Sodium Alerts notify you when you're approaching your daily sodium limit. You can:

• Toggle alerts on or off
• Set a threshold (e.g., 80% of your daily limit)

This is especially helpful for people managing kidney health or blood pressure who need to monitor sodium intake.

PureLog offers multiple ways to log what you eat:

• Chat with Sage - Describe your meal in natural language (e.g., "grilled chicken with rice and steamed broccoli")
• Search Food - Search the USDA and Open Food Facts databases
• Scan Barcode - Scan packaged food barcodes for instant nutrition data
• Scan Nutrition Label - Use your camera to scan nutrition facts panels
• Manual Entry - Enter nutrition values directly
• Recipes - Log saved recipes with calculated nutrition
• Saved Foods - Quickly re-log foods you've saved before

Chat with Sage is the easiest way to log meals using natural language:

1. Go to the Log Food tab
2. Tap the Chat with Sage card at the top
3. Describe what you ate (e.g., "2 eggs with toast and orange juice")
4. Sage will analyze your meal and log it automatically

You can also ask nutrition questions, get meal recommendations, and Sage recognizes your saved foods and recipes.

Scanning a Barcode:

1. Tap Scan Barcode in Quick Actions
2. Point your camera at the product's barcode
3. The app will automatically detect and look up the product
4. Review the nutrition information and tap Add

Scanning a Nutrition Label:

1. Tap Scan Nutrition Label in Quick Actions
2. Point your camera at the nutrition facts panel
3. PureLog will extract the nutrition values automatically
4. Review and adjust if needed, then tap Add

1. Tap Manual Entry in Quick Actions, or select a meal type (Breakfast, Lunch, Dinner, Snack)
2. Enter the food name
3. Fill in the nutrition values (calories, protein, carbs, fat, etc.)
4. Tap Save

Saved Foods shows items you've saved before, making it quick to re-log frequent meals:

1. Tap Saved Foods in Quick Actions
2. Browse or search your saved items
3. Tap an item to add it again
4. Adjust the quantity if needed

Yes! To edit or delete an entry:

1. Go to the History tab
2. Find the entry you want to modify
3. Tap on it to view details
4. Use the Edit or Delete options

History and Saved Foods are separate. If you also saved this food to your Saved Foods, editing or deleting the logged entry here won't affect it: deleting a History entry leaves the Saved Food in place, and editing a History entry's values doesn't change the saved version — your Saved Food keeps its original numbers. To change or remove the saved version, edit or delete it directly from the Saved Foods list.

PureLog supports four meal types:

• Breakfast
• Lunch
• Dinner
• Snack

Selecting a meal type helps organize your daily intake and provides better insights in your history.

• Recipe ingredients - Ingredient lists for AI analysis

This data is processed to provide nutrition information and is not stored by us. Your food logs, health data, and personal information remain on your device.

PureLog widgets let you track your nutrition progress at a glance without opening the app. You can add widgets to your:

• Home Screen - See nutrition progress alongside your other apps
• Lock Screen - Quick glance at your daily progress

Widgets are free and update automatically as you log food throughout the day.

To add a widget to your Home Screen:

1. Long-press on your Home Screen until apps start jiggling
2. Tap the + button in the top corner
3. Search for PureLog
4. Choose a widget size and tap Add Widget
5. Drag it to your preferred location

For Lock Screen widgets, go to Settings > Wallpaper > Customize and add widgets to your lock screen.

PureLog offers several widget options:

• Small (Single Nutrient) - Shows one nutrient with a circular progress ring. You can configure which nutrient to display.
• Medium (Rest of Day) - Shows 4-5 nutrients with progress bars, tailored to your health profile.
• Lock Screen - Compact widgets showing your primary nutrient or a brief summary.

Yes! For the small (single nutrient) widget:

1. Long-press the widget on your Home Screen
2. Tap Edit Widget
3. Select the nutrient you want to track (Calories, Protein, Sodium, etc.)

The medium widget automatically shows nutrients based on your health profile (general wellness, kidney health, or heart health).

Widget colors indicate your progress:

• Green - Working toward a goal (calories, protein, fiber)
• Orange - Approaching a limit (sodium, saturated fat, sugar)
• Red - Over your limit or goal

The color logic adapts to your health profile. For example, protein shows as a limit (orange) for users with kidney disease.

Widgets update:

• When you log food in the app
• Every 15 minutes automatically
• At midnight when the day resets

If your widget seems stuck, open PureLog and it will refresh immediately.

The Healthcare Provider Portal lets you share your last 30 days of health data with your doctor, dietitian, or other healthcare provider via a temporary web link.

Your provider can view your data in their browser without installing anything. The link automatically expires after your chosen time period.

This feature is free for all users.

The portal includes your last 30 days of:

• Food logs and nutrition - Daily entries and nutritional totals
• Blood pressure readings - With health category classifications
• Weight entries - With trend visualization
• Sleep data - Duration and quality if logged
• Health profile - Your nutrition goals and health condition settings

No personal identifiers (name, email, etc.) are included - only a random 8-digit verification code.

To share your data with a healthcare provider:

1. Go to Settings > Healthcare Provider Portal
2. Tap Create Portal Link
3. Select how long the link should be active (1, 6, 12, or 24 hours)
4. Tap Create Portal Link
5. Share the link with your provider via text, email, or copy/paste

Your provider opens the link in any web browser to view your data.

When you create a portal link, a random 8-digit verification code is generated (e.g., "04829163").

This code appears on both your phone and the web portal. You can share it verbally with your provider to confirm you're both looking at the same data.

The verification code is the only identifier on the portal - your name and personal information are never included.

Yes! To revoke access immediately:

1. Go to Settings > Healthcare Provider Portal
2. You'll see your active portal with the countdown timer
3. Tap Revoke Access

The data is immediately deleted and the link will no longer work.

Yes, the Healthcare Provider Portal is designed with privacy in mind:

• No personal identifiers - Only a random verification code identifies your data
• Unguessable URLs - Portal links use 32-character random IDs that cannot be guessed
• Automatic expiration - Data is permanently deleted after your chosen time (1-24 hours)
• Manual revocation - You can delete the data anytime before expiration
• One portal at a time - Limits exposure by allowing only one active share

To protect your privacy, PureLog limits you to one active portal link at a time. This prevents accidentally having multiple copies of your data floating around.

If you need to share with a different provider, you can either:

• Wait for your current portal to expire
• Revoke the current portal and create a new one

PureLog can show you current food recalls to help you stay informed about food safety. The Food Recalls feature displays:

• Recent food recall announcements

Recalls are available from United States (FDA), Canada (CFIA), and United Kingdom (FSA).

To view current food recalls:

1. Go to the Health Hub tab
2. Tap Food Recalls

   • United States - FDA food recall data
   • Canada - CFIA (Canadian Food Inspection Agency) recalls
   • United Kingdom - FSA (Food Standards Agency) alerts

The recalls displayed and notifications will be based on your selected country.

PureLog doesn't send push notifications for recalls, but it keeps you informed inside the app:

• The Health tab shows a "New" badge when fresh recalls are available.
• You'll see a brief in-app heads-up the next time you open the app after new recalls are posted.
• Browse the full list anytime in Health Hub > Food Recalls.

To choose which countries' recalls you see, go to Settings > Food Recalls and pick United States (FDA), Canada (CFIA), and/or United Kingdom (FSA).

Food recall data comes directly from official government sources:

• United States - FDA openFDA API
• Canada - Canadian Food Inspection Agency
• United Kingdom - Food Standards Agency

PureLog fetches this data on-demand when you view the Food Recalls screen. No personal data is sent to access recall information.
