Creative workflow prototyping at scale
An iPad creative tool used by internal Adobe product teams to prototype new brush and surface behaviors before committing to the roadmap.
Adobe's internal creative-tools group needed a way to prototype brush-engine changes against real-world workflows without shipping through their regular release train. The brief: a sandbox iPad app that product designers could actually use, not a lab toy.
We shipped in 6 weeks on a fixed-price scope. SwiftUI for the interface, Metal for the brush engine, AWS Lambda + S3 for the backing sync. The app installs from an internal MDM channel and lets designers load surfaces, test brush behaviors, and export comparison recordings for review.
Key decisions: we kept the brush pipeline native-Metal rather than bridging through a cross-platform layer (latency was the whole point), and we let the sync layer lag behind the canvas rather than blocking — the wrong bet would have made the pen feel laggy.
- + kept: Sub-16ms pen-to-pixel latency- cut: Cross-platform code sharing// why: SwiftUI + Metal stayed; a React Native bridge would have doubled the frame budget.
- + kept: Offline-first sketch persistence- cut: Real-time multi-user canvas// why: Designers work solo; multiplayer was theater cost with no user demand.
- + kept: Hardware-accelerated export- cut: In-app video editing// why: Export was the share-ready moment. Editing was Premiere's job, not ours.
