Add Your Brief
Add your context below. It will be included with the prompt when you copy or download.
Create an editable mobile-first app prototype using the existing project stack for [PROJECT] and [AUDIENCE]. The task is: Car Maintenance Log.
Required content and structure
Log a vehicle's mileage and completed service, attach a receipt and maintain reminders based on owner-entered dates or mileage intervals.
Screens and navigation
Build three connected views: Vehicles; Service record; Upcoming tasks. Keep the selected record visible in the screen title or summary. Support an explicit back action and preserve in-progress inputs when moving between views. Keep the primary action near the relevant content and account for mobile safe areas, a visible software keyboard and long translated labels. At desktop widths, adapt the composition without removing a step or changing the task.
Project inputs
Use [APPROVED_CONTENT] for names, records, labels, quantities and destinations. Ask for missing data instead of inventing operational claims. Demonstration records may use the fictional brand Mileage; label these as sample data. Explain which actions are local prototype interactions and which would require authentication, persistence, permissions or a backend. Do not connect external services or claim a transaction was completed unless that integration has been explicitly implemented and tested.
Design direction
Follow [BRAND_RULES]. When no brand is supplied, use light gray, petrol blue, orange accents, precise technical layout. Make the workflow recognizable through its own content and controls, rather than repeating generic dashboard cards. Use a consistent spacing scale and clear text hierarchy. Include visible keyboard focus, accessible names, sufficient contrast and non-color status labels. Respect reduced motion and keep animated transitions optional.
Task-specific acceptance check
- Keep units explicit, flag a decreasing odometer value and avoid claiming manufacturer-approved maintenance advice.
Interaction states
Implement the three-screen happy path with local sample data. Include a useful empty state, validation before completing an action, a loading or pending state and a recoverable failure state. Destructive changes require a review or undo path. Keep the state of a record consistent across all three views. Do not silently discard partially completed input or change a user's choice after a retry.
Delivery and review
Return the editable app views and explain the data model, any local storage behavior and unimplemented integrations. Test at 320px and a wider viewport, with keyboard navigation and long content. Use the task-specific acceptance check above to review the result before adding features. Keep demonstration behavior clearly distinct from a running production service.
Reference attachment and reconstruction goal
Attach reference.webp from this prompt’s download bundle alongside this prompt in OpenDesign. Build an editable result with a similar composition and hierarchy; do not embed the whole reference image as the finished interface. Preserve approved project content and brand rules if they conflict with fictional sample labels. If the image is missing or unreadable, ask for it instead of claiming visual fidelity.
Reference composition and content
Use the attached reference.webp as the visual reference for Car Maintenance Log. Before building, identify the major regions from top to bottom, their relative widths and heights, alignment, spacing, typography hierarchy, surface colors, borders, imagery and repeated components. Preserve those relationships rather than substituting a generic template. Required task content: Log a vehicle's mileage and completed service, attach a receipt and maintain reminders based on owner-entered dates or mileage intervals. Use the following task-specific layout guidance when translating the image into editable elements: Begin with Vehicles as the entry screen, give Service record a clear primary action, and make Upcoming tasks explain what happened and what can happen next. Use light gray, petrol blue, orange accents, precise technical layout as a starting direction, adapting it to the supplied brand. Keep record identity and navigation context visible across the three screens. Prioritize thumb-accessible controls and readable labels over decorative panels; on wider screens, keep the workflow coherent rather than stretching a mobile composition edge to edge.

Interaction specification
The reference is a static concept: the behavior below is a requirement to implement, not proof that the picture already works. Copy the customized prompt into your project and build the connected flow: Log a vehicle's mileage and completed service, attach a receipt and maintain reminders based on owner-entered dates or mileage intervals. Keep units explicit, flag a decreasing odometer value and avoid claiming manufacturer-approved maintenance advice. For each visible control, specify its trigger, affected state and feedback; implement local changes with consistent state across related views. Give search and filters real results, selection controls an explicit active state, and save actions visible pending/success/failure feedback where relevant. Do not add unrelated workflows. Use proper links for navigation, buttons for actions and accessible names for icon controls. Do not imply a backend operation succeeded when only a local demo changed.
Visual comparison and delivery
- Compare the result with the attached image at matching proportions. Review major region placement, relative image sizes, line breaks, spacing, typography hierarchy, contrast, active states and content density before polishing decorative details.
- Then test the narrow layout without squeezing desktop text into tiny labels.
- Keep logos, photos and icons as separate assets and all meaningful labels editable. List any unavailable fonts/assets and any intentional departures. Return the working files plus a concise account of implemented behavior and remaining integrations; do not promise a pixel-identical result from the prompt alone.

How to Write a Car Maintenance Log Design Prompt
Use this car maintenance log design prompt to log a vehicle's mileage and completed service, attach a receipt and maintain reminders based on owner-entered dates or mileage intervals.
The reference is an AI-generated concept. The instructions below describe what to build and test; the image does not demonstrate working behavior.
Keep the Vehicle and Units Explicit
A car maintenance log records owner-entered history, not a maintenance diagnosis.
Mileage, dates and receipts need to remain attached to the correct vehicle and service. Begin with Vehicles as the entry screen, give Service record a clear primary action, and make Upcoming tasks explain what happened and what can happen next. Use light gray, petrol blue, orange accents, precise technical layout as a starting direction, adapting it to the supplied brand. Keep record identity and navigation context visible across the three screens. Prioritize thumb-accessible controls and readable labels over decorative panels; on wider screens, keep the workflow coherent rather than stretching a mobile composition edge to edge.
From the Prompt
Build three connected views: Vehicles; Service record; Upcoming tasks.
Make It Your Own
Show [VEHICLE] with its odometer unit, completed services and receipt attachments. Let the owner set date- or mileage-based reminders, keeping those rules visible.
Prepare the Car Maintenance Log Content
The middle screen shows a mileage field with an inline warning, service type, notes and a receipt. Define validation against the previous reading before saving a record.
Supply fictional vehicle records with an odometer unit, service dates, recorded mileage and receipt examples. Define the owner's reminder intervals separately; include an older mileage entry to test how corrections are reviewed.
From the Prompt
Log a vehicle's mileage and completed service, attach a receipt and maintain reminders based on owner-entered dates or mileage intervals.
Make It Your Own
For [PROJECT], use [APPROVED_CONTENT] as the source for this car maintenance log. Approved records and field labels for Vehicles; Service record; Upcoming tasks; the action and persistence rules; brand assets and permission requirements. Identify missing inputs before replacing them with demonstration content.
Enter a Lower Odometer Reading
The final screen groups due-soon and later tasks, with miles or months beside each item. Check that reminders use the correct unit and that completion updates the vehicle record.
Flag the decrease for review without silently replacing history. A reminder should be described as owner configured, not as a manufacturer-approved service recommendation. Test this specific boundary first: Keep units explicit, flag a decreasing odometer value and avoid claiming manufacturer-approved maintenance advice. Then run the main flow with a long record title, no saved records and a failed action. A user should be able to tell what is saved, what is pending and what can be undone without relying on color. Verify that returning to the previous screen preserves entered data and that a screen reader encounters the title, status and primary action in a sensible order.
