The company also positions project audit and rescue as a current service. Its work is particularly relevant to financial applications where the mobile architecture connects with payment systems, cloud infrastructure, compliance requirements, and complex backend services. Audit findings can lead into controlled refactoring, stabilization, or re-architecture.
Appinventiv has a dedicated mobile app consulting practice that covers architecture and platform consulting, portfolio audits, modernization strategy, integration architecture, security, and existing-app rescue. Its technical and codebase health audit examines architecture, code quality, dependencies, and technical debt before separating components that can be retained from those that may need rebuilding.
The audit can also incorporate performance diagnostics, stability analysis, security and compliance gaps, and data continuity planning. It is suited to larger mobile environments where architecture cannot be evaluated separately from APIs, enterprise systems, governance, and backend infrastructure.
21century.tech is an AI-native software studio where senior engineers retain responsibility for architecture, design, business logic, security decisions, code review, QA, and final production quality. Its capabilities include full-stack development, legacy refactoring, integrations, test coverage, documentation, CI/CD, and production deployment.
A-listware works with existing mobile applications through modernization, architecture redesign, code refactoring, QA, security assessment, integrations, and application support. Its mobile development service specifically includes reworking legacy applications through architectural redesign and code refactoring.
The company is a better fit when an architecture audit is expected to lead into engineering work rather than remain a standalone advisory exercise. A-listware can examine an existing application through consulting, testing, and security assessment, then provide development resources for restructuring the mobile app and its connected systems.
Miquido approaches architecture assessment largely through application modernization and project takeover work. Its modernization process begins with a structured technical assessment of architecture, dependencies, crash patterns, and CI/CD maturity across iOS and Android, followed by a prioritized modernization plan.
The company also provides mobile engineering consultations that evaluate an application's current architecture and operational load. This makes Miquido relevant when the main purpose of an architecture audit is to decide how an unstable or outdated mobile product should be stabilized, modernized, migrated, or restructured.
Mobian is primarily a mobile and software development partner rather than a dedicated audit provider, but its work includes architecture assessment and planning around existing products. The company builds iOS, Android, and Flutter applications and states that clean architecture, test coverage, documentation, performance monitoring, and scale planning are standard parts of its engineering process.
Its engagement process begins by assessing an existing product and identifying gaps before deciding how specialists should support the team. Mobian is therefore more relevant to architecture reviews that are expected to lead into modernization, team augmentation, or continued mobile development.
OSKI's mobile engineering services cover architecture, native and cross-platform development, backend integration, security, testing, CI/CD, and modernization. Its enterprise mobile process starts by mapping security requirements, devices, integrations, and other technical constraints before the team defines identity, data, offline, integration, and deployment architecture. Its approach is more suitable for teams that want assessment and architecture work to form the opening stage of a larger modernization, enterprise integration, or redevelopment engagement.
Inoxoft offers a dedicated Technical Software Audit that includes both a Mobile App Code Audit and a Solution Architecture Audit. Its mobile assessment covers native and cross-platform iOS and Android applications, with attention to performance, responsiveness, and maintainability.
The wider audit also examines backend architecture, frontend structure, security, databases, cost optimization, and technical risks. Inoxoft provides an audit report containing architecture review findings and a roadmap, making it particularly relevant when decision-makers need one assessment covering both mobile code and the surrounding software architecture.
Droids On Roids provides code audits, technology capability audits, product audits, regression testing, and technical discovery for mobile products. Its Android service includes an in-depth code audit alongside architecture capabilities such as Clean Architecture, modularization, data synchronization, reactive programming, and offline operation.
For existing products, the company's Product Discovery process can analyze technology risks, legacy dependencies, integrations, user data, and business requirements before producing recommendations for future development. This broader approach makes the firm useful when architecture quality needs to be considered alongside product behavior and technical feasibility.

net-devs takes a broader enterprise engineering approach, with senior engineers responsible for architecture, technical trade-offs, code review, testing, and final quality. Its service catalog includes an AI-accelerated enterprise codebase audit and modernization roadmap, while its team includes mobile engineering expertise.
Its stronger fit is an application where the mobile component depends on enterprise backends, cloud architecture, integrations, or a wider legacy platform that also needs assessment.
Infinum has documented architecture-review experience in inherited mobile codebases. In one project takeover, senior engineers reviewed existing iOS and Android applications and produced a written assessment covering dependencies, codebases, architecture, packages, and data layers, followed by prioritized action points.
The company also maintains established internal architecture practices for mobile development and offers broader app audits in areas such as usability and accessibility. Infinum is well suited to organizations that need senior engineers to understand an inherited application before committing to a takeover, refactor, redesign, or longer modernization program.

Teams with mobile front ends connected to .NET, Azure, AWS, or enterprise backend systems may find the company's broader architecture and modernization experience particularly relevant.
Andersen provides technical audits, architecture analysis, application security assessments, mobile security testing, and mobile development. One banking project involved architectural analysis of the systems supporting a consumer mobile application, documentation of the current architecture, identification of critical risks, and recommendations for improvement.
Its broader application security work also evaluates architecture, trust boundaries, authentication, mobile dependencies, APIs, source code, and design-level weaknesses. This makes Andersen relevant where architecture auditing needs to include security, compliance, backend dependencies, and enterprise integration rather than focusing only on the mobile client code.
A mobile app architecture audit can serve different purposes, from evaluating an inherited codebase to planning modernization, restructuring, or a larger redevelopment project. The companies in this list cover a broad range of architectural concerns, including code quality, dependencies, scalability, security, integrations, backend systems, and technical debt.
When choosing a provider, teams should first define the scope of the assessment and the technical questions the audit needs to answer. A standalone architecture review may be sufficient for a focused evaluation, while legacy or enterprise applications can require analysis of APIs, cloud infrastructure, security controls, data flows, and connected systems. Some providers also combine assessment with refactoring, modernization, or development, which can be relevant when architectural findings need to inform subsequent engineering work.
A well-defined scope, relevant experience with the app's technology stack, clear deliverables, and a documented plan for addressing identified issues can help teams turn an architecture assessment into a practical roadmap for the next stage of the product.
