   bestFor

   Before: ["Clients needing fast, high-quality mobile app development with AI-assisted coding and senior engineer oversight.","Clients requiring urgent fixes and same-day help for production issues."]

   After: ["Clients needing fast, high-quality mobile app development with AI-assisted coding under senior engineer oversight.","Organizations requiring senior-level engineering without juniors or account managers, with direct communication and no handoffs."]

   features

   Before: ["Use of fleets of coding agents and latest AI models to handle scaffolding, tests, refactors, and store metadata.","Senior engineers direct and review every design call and merged line of code.","Automated test suites gate every build to ensure quality before shipping to the App Store."]

   After: ["Mobile app development end to end for native iOS and macOS apps using Swift and SwiftUI.","Use of fleets of AI coding agents to handle scaffolding, tests, refactors, and store metadata.","Senior engineers direct and review every design call and merged line of code to ensure quality.","Automated test suites gate every build to maintain quality before shipping to the App Store."]

   limitations

   Before: []

   After: ["Focus is primarily on mobile apps but also covers AI/LLM systems, backend, and distributed systems; not a generalist software consultancy."]

   summary

   Before: "p99.studio is a senior engineering studio specializing in mobile app development for iOS and macOS using Swift and SwiftUI, leveraging AI coding agents under senior engineer supervision to deliver projects quickly and with high quality. They also handle inherited codebases, backend, AI/LLM systems, and distributed systems, providing same-day fixes and ongoing support with clear ownership of code and IP."

   After: "p99.studio is a senior engineering studio specializing in mobile app development for iOS and macOS using Swift and SwiftUI, leveraging AI coding agents under senior engineer supervision to deliver projects quickly. They also handle inherited codebases, backend, AI/LLM systems, and distributed systems with a focus on quality and speed."

   useCases

   Before: ["Developing native iOS and macOS mobile applications from design to store shipping.","Taking over and improving existing or inherited codebases, including half-finished projects and systems with missing original authors."]

   After: ["Taking over and improving inherited or half-finished codebases where original authors are unavailable.","Providing urgent same-day fixes for production issues or critical deadlines."]

   walkthrough

   Before: ["Clients start by discussing scope and timeline on a call to get a real timeline estimate.","Code and IP ownership remain with the client from day one, with all code living in the client's repositories and accounts."]

   After: ["Start with a first call to get a real timeline estimate; a first working build usually takes days, with a shippable version in weeks.","AI coding agents handle scaffolding, tests, refactors, and metadata, while senior engineers direct and review all code merges.","Tests and reviews gate each merge to ensure the build is stable and reliable before shipping to the App Store."]
