"I've worked with ONE° on several projects over the years, and it's always been a positive experience. Building a website can get complicated, especially with multiple stakeholders involved, but they bring a steady, can-do approach that really helps keep things moving. They listen closely to what clients want and offer thoughtful, practical solutions—especially when the challenges aren't straightforward."

[FAQ]

Frequently
Asked.

App design projects start at $15,000 for a simple app (10-15 screens). Most apps with moderate complexity cost $25,000–$50,000. Complex apps with many features, both platforms, and extensive prototyping can exceed $75,000. We provide fixed quotes after scoping.
We focus on design and can recommend trusted development partners. We work closely with your development team or partner, providing specs, assets, documentation, and ongoing support for accurate implementation.
You receive organised Figma files with all screens, a component library, exported assets (icons, images), animation specifications, and developer handoff documentation. Everything needed to build the app accurately.
Yes. User research can include stakeholder interviews, user interviews, competitor analysis, and usability testing. Research is highly recommended for new products or redesigns—it reduces risk and improves outcomes.
Yes. App redesigns start with auditing your current app's UX, identifying pain points, and creating improved designs. We can do incremental improvements or complete visual overhauls depending on your needs.
Yes. We design mobile apps for businesses across Tasmania, Melbourne, Sydney, USA, and Canada. We're based in Ulverstone, Tasmania and collaborate effectively with clients anywhere via video calls and shared Figma files.
Yes. App icons, App Store/Play Store screenshots, and promotional graphics can be included or added as a separate deliverable. Strong store presence significantly impacts download rates.
Simple apps take 4-6 weeks. Medium complexity apps take 8-12 weeks. Complex apps with user research, testing, and extensive prototyping may take 12-16 weeks. We'll provide a timeline after understanding your requirements.
Both. We can design platform-specific interfaces that follow iOS and Android conventions, or a unified design system for cross-platform frameworks like React Native or Flutter. We'll recommend the best approach for your goals and budget.
We create clickable Figma prototypes that simulate the real app experience. You can tap through screens on your phone, share with stakeholders, and conduct user testing before investing in development.
Great. We'll collaborate with your developers from day one, ensuring designs are feasible and handoff is smooth. We're experienced working with in-house teams, agencies, and freelance developers.
Yes. If your app needs tablet versions, we design adaptive layouts that take advantage of larger screens. Tablet design is quoted based on the number of unique layouts required.
We include 2-3 revision rounds at each stage (wireframes, UI design, prototypes). Our thorough discovery process means we usually nail the direction early, but we continue until you're happy with the result.
