# Build brief — an original mobile app in the taste of Notion Mail
> Reference: https://mobbin.com/apps/notion-mail-ios-1542f936-6677-4eae-890c-cbce751475a1/a2be653b-64d2-43de-833f-ebe8740744a9/screens · UIDiscovery: https://uidiscovery.com/sites/ios-notion-mail · captured 2026-09-23
## 1. Goal
Build an original mobile app for **[the user's brand]** that feels as considered as Notion Mail — same structure, rhythm and polish, entirely new identity and content. Stack: SwiftUI, React Native/Expo, or a mobile-first web app.
## 2. Originality rules
- Build an ORIGINAL design for the user's own brand in the same *taste* as Notion Mail: structure, rhythm, hierarchy, palette mood and type pairing.
- Never reuse Notion Mail's logo, name, product imagery, illustrations, icons, screenshots or copy. Write new copy for the user's product.
- If the user hasn't said what their product is, ask first (or use clearly marked placeholders like [Brand], [Product], [Audience]).
- Reference screenshots are for looking at, not for embedding or tracing.
## 3. The taste, in short
- Notion Mail is a Technology iOS app; 95 screens captured.
- Screens are captured from the app itself.
- Palette and fonts are NOT measured for iOS references — sample them from the screenshots.
## 4. Screens
Every screen needs: Status bar + navigation; Primary content; Primary action / tab bar; Empty and loading states.
1. [Name the account prerequisite](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0000-dea3272fa561.webp) — The welcome screen says to continue with a Notion account and provides Get started.
2. [Show the account-method menu](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0001-59ee18f5159c.webp) — A notion.so browser sheet lists Google, Apple, Microsoft, Passkey, SSO and Email.
3. [Expand the chosen email method](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0002-d63f1a8cb8a7.webp) — An email field and Continue action sit below the provider menu in the browser sheet.
4. [Retain the entered address](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0003-f3c26f77938d.webp) — The filled email field offers a clear control and a Continue button.
5. [Request the emailed code in place](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0004-3562ab392858.webp) — A verification-code field appears beneath the email field with a sent-to-inbox explanation.
6. [Make verification submission explicit](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0005-9ec80c96f9d0.webp) — The code is filled and a Continue action remains below the fields.
7. [Acknowledge account setup work](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0006-458b1c782c10.webp) — The browser sheet shows a spinner and Getting set up text in the center.
8. [Separate identity from mailbox connection](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0007-392542113367.webp) — A Connect Gmail address sheet explains mailbox connection and offers Continue with Gmail.
9. [Expose the provider handoff](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0008-872425e93706.webp) — An iOS dialog names accounts.google.com and offers Cancel and Continue above the connection sheet.
10. [Ask for notifications over the destination](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0009-4467235dbaac.webp) — An Enable push notifications sheet overlays the inbox and explains updates on new messages and replies.
11. [Keep service notices visible in the inbox](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0010-41f059b074b5.webp) — The inbox contains message rows, search and compose controls beneath a yellow service notice.
12. [Reserve a clear draft structure](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0011-db7fe559c265.webp) — The compose view separates recipient, subject and body, with attachment and calendar controls and a muted Send action.

## 5. Design system
- Colour: not measured. Sample background, text, accent and surface from the screenshots, then check contrast.
- Type: SF Pro natively (Dynamic Type: Large Title 34, Title 22–28, Body 17, Footnote 13); on the web use Inter or system-ui at the same sizes.
- Layout: 16–20pt side margins, 44pt minimum tap targets, safe areas, tab bar or navigation stack as seen in the screens; cards with 12–20pt radii are typical — confirm in the screenshots.
## 6. Imagery plan
iOS references show the product UI itself: build screens in code. What you still need to source is the content imagery inside them (covers, thumbnails, onboarding art).
### Slot 1 · All 12 screens → product UI
- iOS screen: the visual is the app UI itself; any photos/illustrations inside it are content. Count: one consistent treatment across these sections. Aspect: 9:16 (portrait, phone). Look first: [ref 1](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0000-dea3272fa561.webp) [ref 2](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0001-59ee18f5159c.webp) [ref 3](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0002-d63f1a8cb8a7.webp) [ref 4](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0003-f3c26f77938d.webp)
- Build every screen in code. Don't reproduce App Store marketing frames or the app's own artwork.
### Slot 2 · In-app content imagery (covers, thumbnails, onboarding art) → photography (uncertain)
- Technology apps often use photography for content — not measured; check the screenshots. Count: one consistent style across all content. Aspect: 1:1 thumbnails, 4:5 covers. Look first: [ref 1](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0000-dea3272fa561.webp) [ref 2](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0001-59ee18f5159c.webp) [ref 3](https://uidiscovery.com/media/captures/ios-notion-mail/sep-2026/0002-d63f1a8cb8a7.webp)
- **Stock** — “abstract gradient mesh”: [Unsplash](https://unsplash.com/s/photos/abstract-gradient-mesh?orientation=landscape) · [Pexels](https://www.pexels.com/search/abstract%20gradient%20mesh/?orientation=landscape) · [Pixabay](https://pixabay.com/images/search/abstract%20gradient%20mesh/?orientation=horizontal)
- **Generate** — `Photograph: abstract gradient mesh. Composition: centred subject with even space around it. Lighting: soft natural daylight, airy and high-key. Neutral, desaturated colour grade that sits on colours sampled from the reference screenshots. Photorealistic, natural textures, shallow depth of field, 35mm lens. Aspect ratio 16:10. No text, no letters, no logos, no watermarks, no brand marks or trademarked products, no recognisable real people.`
- **Licences:** Unsplash and Pexels images are free for commercial use under their own licences; Pixabay under the Pixabay Content License. Check each image's page before use, credit the photographer when asked (good practice anyway), and skip images showing logos, trademarks, branded products or identifiable people without a release.
- **AI generation:** the prompts work with any image model (GPT Image, Imagen, Flux, Midjourney, Firefly, SDXL…) — check its commercial-use terms. Never put the reference brand's name or “in the style of <brand>” in a prompt.
- **Never** download, trace or re-host the reference's own images, illustrations, product shots or logos.
## 7. Build steps
1. Confirm brand, product, audience and the primary action with the user.
2. Pick the stack and define colour/type tokens sampled from the screenshots.
3. Build the navigation shell first, then each screen, with each reference screenshot open.
4. Write original copy for every slot — match length and tone, never the words.
5. Source every image via the imagery plan (stock or generated); compress it and record credits.
6. Run the checklist at 390 / 768 / 1440px and fix what fails.
## 8. Acceptance checklist
- [ ] Responsive at 390px, 768px and 1440px — no horizontal scroll, tap targets ≥ 44px on mobile.
- [ ] Colour contrast WCAG AA: 4.5:1 body text, 3:1 large text and UI; visible focus states; full keyboard navigation.
- [ ] Semantic HTML: one <h1>, ordered headings, landmarks (header/nav/main/footer), labelled form fields, alt text on meaningful images.
- [ ] Performance: modern image formats with width/height set, lazy-load below the fold, ≤ 2 font families with font-display: swap, LCP < 2.5s.
- [ ] prefers-reduced-motion respected; animations under ~300ms and never blocking content.
- [ ] Originality: no copied logos, images, illustrations or copy from the reference; every image licensed or generated; credits recorded.
## 9. If you use Next.js + Tailwind
Mobile web: App Router + Tailwind, `viewport-fit=cover` with safe-area insets, a fixed bottom tab bar, components designed at 390px first.
