Martin Höller offers freelance iOS and macOS development services, rather than a traditional SaaS developer tool. The positioning is clear: helping startups and product teams turn Apple-platform ideas into shippable native apps. He can also join an existing team as a senior engineer to help with feature delivery, architecture decisions, and release quality.
The service covers iPhone, iPad, Mac, Apple Watch, and tvOS, with visionOS support possible depending on the project. The core technical stack includes Swift, SwiftUI, async/await, Combine, Swift Data, Core Data, Objective-C, RxSwift, MVVM, and software architecture. The site also mentions additional skills such as Python, JavaScript, NodeJS, Ruby, and Kotlin Multiplatform, but the main focus remains the native Apple ecosystem. The FAQ clearly states that he does not do Android and does not use Flutter or React Native, making this a fit for projects that prioritize a native platform experience rather than cross-platform projects aiming to cover multiple platforms at once.
Beyond coding, he provides code and architecture reviews, team bootstrapping, build/release/QA process automation, coaching on Swift and testing best practices, and App Store compliance advice related to subscriptions and in-app purchases. Past work includes projects such as Bosch eBike Flow, OpenEmail, Douglas, Deutsche Bahn, Clue, and Thalia, covering areas like BLE communication abstraction, complex UI, internal SDK prototypes, e-commerce, and health apps. The delivery process is described as first clarifying goals, risks, and milestones, then building in small iterations and supporting launch.
The website only offers a free 20-minute call and product idea assessment. It does not publish hourly rates, project quotes, payment methods, or long-term maintenance fees. As an individual freelancer, his strengths are a short communication chain and concentrated expertise; the limitations are that capacity, scheduling, and service SLA need to be confirmed separately.
The main advantages are deep focus on Apple platforms, solid production project experience, and coverage across engineering quality, architecture, team coaching, and monetization compliance. The downsides are opaque pricing, no Android or cross-platform development, and the fact that this is not a self-hostable or directly purchasable tool product. It is best suited for startups and product teams that need a senior iOS/macOS expert for MVP development, architecture review, team augmentation, or implementation of complex features.
The site does not provide information about access from mainland China, payments, or invoicing. In practice, communication may be affected by network access, time zones, and cross-border payment arrangements. If localized communication and payment are required, domestic iOS outsourcing teams may be worth considering. For international freelance platforms, alternatives include Toptal, Arc.dev, Gun.io, and Upwork.
