How can we help?

First, force-quit the app and reopen it. If the issue persists, go to Settings → General → iPhone Storage → Washoku Plus and tap Offload App, then reinstall from the App Store. Make sure you're running iOS 16 or later.

Still stuck? Check your internet connection — some features require a live connection on first launch.

Go to Profile → Dietary Preferences and tap Save after making any changes. If preferences reset after closing the app, sign out and sign back in to re-sync your profile from the server.

If you're using the app offline, changes will sync automatically the next time a connection is available.

Navigate to Meal Plan → Week View and tap the three-dot menu in the top-right corner. Select Reset Week or Start Fresh. This will clear the current week's plan but preserve your meal history and saved recipes.

Washoku Plus uses official references for educational nutrition and allergy guidance. Nutrition estimates are based on USDA FoodData Central and the FoodData Central API Guide.

General meal-pattern language references Dietary Guidelines for Americans and CDC Healthy Eating Tips.

Allergy information references FDA Food Allergies and FDA Food Allergen Labeling Guidance. Ingredient lists can vary, so verify labels and restaurant details.

Double-check that caps lock is off and your email matches the one you registered with. Use Forgot password on the sign-in screen to receive a reset link.

If you signed up via Apple or Google, tap the corresponding button on the sign-in screen — these accounts don't use a separate password.

If the reset email doesn't arrive within 5 minutes, check your spam folder or submit a support issue below.

Make sure you're signed in with the same account on both devices. Open the app on each device while connected to Wi-Fi — sync happens automatically within a few seconds.

If data is still out of date, pull down on the main screen to force a manual refresh. If the problem continues, let us know.

Go to Profile → Settings → Delete Account. This will permanently remove your account, meal history, and all personal data within 30 days as required by applicable privacy laws.

You can also request deletion by emailing hello@washoku.plus with the subject line Delete My Account.

Subscriptions are managed through the App Store. On your iPhone go to Settings → [your name] → Subscriptions, find Washoku Plus, and tap to modify or cancel.

We do not have the ability to manage App Store subscriptions directly — Apple handles all billing for iOS purchases.

The Companion feature requires an active connection to generate new insights. Verify you have internet access, then pull-to-refresh the Home screen. If the issue persists after a force-quit, submit a report and include your device model and iOS version.
