Whether you’re building a digital wallet for bilingual users in Montréal, a gig-work platform with geo-location features in Toronto, or a content-on-demand app that needs fluid onboarding in Vancouver—your interface either gets used or gets closed. There’s no in-between.
At Pearl Lemon Web, we work closely with founders, product owners, and engineering leads across Canada to produce interface systems that aren’t just attractive—they’re architected to meet product goals and withstand actual usage. That means UI that aligns with dev stack realities, platform guidelines, and user behaviours common to Canadian demographics, from iOS users in Ontario’s startup scene to Android-heavy user bases in Alberta’s logistics sector.
Interface Systems That Work Where Real Users Tap, Scroll, and Buy
We don’t offer templates. We build interface systems that work with your stack, your sprint, and your users’ behaviour—whether they’re on an iPhone in Toronto or testing Android beta builds in Alberta. Below are our core mobile UI design services, structured for technical teams, founders, and PMs who need usable output, not conceptual fluff.
Mobile UI Architecture & Design Systems
We create modular UI foundations that align with your codebase, follow atomic design principles, and reduce front-end inconsistencies across platforms. This ensures scalable design growth without version mismatch.
- Each component is built as a variant in Figma with structured naming and constraints.
- Design tokens are mapped for direct use in frameworks like Tailwind CSS or Material Theming.
- We match icon sizes, spacing rules, and colour systems for exact consistency in iOS and Android.
- Light and dark modes are fully developed with system theme responsiveness.
UX Wireframing and Clickable Prototyping
We produce interactive wireframes that map out real user flows and edge cases, built for quick validation with stakeholders and dev teams.
- Clickable prototypes are created for onboarding, sign-up, booking, checkout, and profile flows.
- We annotate screens for dev and QA with user intent notes, error state visuals, and success triggers.
- Prototypes include accessibility notes and mobile-specific breakpoints (min-width 320px).
- Ready for use in stakeholder demos, pitch decks, or early usability testing with users.
UI for iOS, Android, and Cross-Platform Builds
We craft UI that aligns with the Human Interface Guidelines for Apple and Material You for Android, while supporting hybrid environments like Flutter or React Native when needed.
- Component structures are delivered for native elements like tab bars, accordions, snackbars, and sheets.
- We use size-specific assets and font guides optimised for pixel ratio across Apple and Android devices.
- UI is delivered for screen sizes from 320px to 1280px, including foldables and tablets.
- Builds are tested visually in both iOS and Android emulators for design accuracy before handoff.
UX Audit and Interface Rework
Already have a product in-market but it’s not converting? We audit current UI with a technical eye—mapping flows, identifying friction points, and rebuilding what’s broken with usable, testable updates.
- We run diagnostic reviews using session recordings, user heatmaps, and crash reports.
- UX repairs are mapped to reduce form abandonment, drop-off mid-flow, and navigation bloat.
- Visual hierarchy, font pairing, and layout prioritisation are restructured for clarity and speed.
- We document all UX assumptions, map user intent, and test against your active metrics (CTR, engagement, drop rate).
Accessibility and Compliance-Ready UI
If you’re building for finance, healthcare, education, or government in Canada, accessibility isn’t optional. We design interfaces that meet required standards and are tested for compliance readiness.
- UI built to meet AODA and WCAG 2.2 standards for colour contrast, tab order, and ARIA labels.
- Input field spacing, target sizing, and visual states are compliant with mobile accessibility guidelines.
- Multilingual UI systems are built for English/French parity, meeting Québec’s localisation requirements.
- Handed-off design files include accessibility tags and audit checklists to support formal reviews.
Why Choose Us
We aren’t an agency with a folder of moodboards and half-baked style guides. We’re a system-driven product design crew working side-by-side with your sprint velocity and staging reality. Our clients include app founders in Toronto, compliance teams in Montreal, and dev shops across Vancouver.
We’ve rebuilt UIs mid-sprint, during code freeze, and two weeks before launch—because we know that’s how product work happens in real life.
Frequently Asked Questions
Yes, we’ve shipped multiple projects with Flutter. We deliver design files that account for PixelPerfect alignment and material theming via Flutter’s widget hierarchy.
Absolutely. We design with adaptive theming rules so your UI dynamically responds to the OS-level dark/light mode setting.
We build modular UI containers for EN/FR toggle and match font weights, glyph handling, and character limits accordingly—no truncation issues on long-form French content.
We deliver fully structured Figma files with nested components, variants, auto-layout, and documentation. Not just mockups—production-ready systems.
Yes. We routinely join sprint grooming, design QA, and post-release retros using Jira, Notion, or Slack. We integrate into your actual team rhythm.
Ready for Interface Work That Speaks Fluent Product?
We’ve built mobile UI systems for SaaS dashboards, eComm carts, mobile banking, booking apps, and B2B marketplaces across Canada. You’re not just buying design—you’re hiring execution that knows what version control means and where your burn rate is.
