App design, development and maintenance

Professional-grade app products, built with taste and kept healthy after launch.

Itch.studio is the studio behind TimerStack and other Apple-first product work. We shape interfaces, build native apps and stay involved after launch so the product keeps getting sharper with use.

What the studio does

Move an app from idea to product system, then keep improving it once real users show up.

01

Design

Product framing, interface direction, layout systems and the judgement needed to make an app feel deliberate from the first screen.

02

Development

SwiftUI-led implementation, API integration, Apple platform capabilities and the engineering discipline required for a real release pipeline.

03

Maintenance

Bug fixing, feature refinement, design clean-up, release support and the less glamorous work that separates a launch from a durable product.

Selected work

Selected work that shows the level of product thinking, craft and follow-through the studio brings to every engagement.

Design tooling

UI Palette Designer

A focused utility for building and exporting colour systems, designed with the same care for workflow, clarity and accessibility.

Creative AI product

PoeticAI

A compact AI product that shows how even smaller app ideas can ship with a clear concept, strong UI judgement and production discipline.

Diagnostics utility

bluetooth.itch

A technical utility shaped by real Bluetooth workflows, where usefulness, speed and technical clarity matter more than feature theatre.

Approach

Clarify the product, build it cleanly, then stay close enough to improve it properly.

01

Shape the scope

Work out what matters now, what should wait, and where product complexity actually earns its place.

02

Design for implementation

Use real UI constraints, platform behaviour and content hierarchy from the start rather than decorating in hindsight.

03

Support the long tail

Stay responsible for updates, fixes, refinements and the maintenance work that keeps a shipped app credible.

Ongoing maintenance

Retainers for teams that need an app kept current, compliant and steadily improving.

Launching is only the beginning. These plans cover Apple platform updates, App Store changes, accessibility and HIG alignment, localisation support for existing flows, and a defined block of time each month for refinement work.

Essential care

For stable apps that need compatibility, oversight and a reliable owner.

From £950/month

  • 4 hours of changes each month
  • iOS and iPadOS release readiness checks
  • SDK, dependency and App Store policy review
  • Minor bug fixing and submission support

Studio partner

For teams that want an ongoing product, design and engineering partner.

From £3,800/month

  • 24 hours of changes each month
  • Priority turnaround and monthly planning
  • Deeper product review across roadmap and releases
  • Coordination with your wider team when needed

What these plans cover

Compatibility work for new Apple OS releases, HIG and accessibility alignment, App Store compliance, localisation maintenance, release preparation and the steady product clean-up that shipped apps always need.

What gets scoped separately

Major new features, backend rebuilds, full redesigns, large-scale localisation projects and urgent out-of-hours work sit outside the monthly allocation and are quoted separately.

Contact

If your app needs strong product judgement, clean execution and support after launch, let's talk.

Itch.studio works from the UK with founders and teams who want Apple-focused apps, thoughtful presentation and reliable follow-through once the product is live, whether that means a new build or an ongoing maintenance retainer.
