Onix offers software project rescue services alongside mobile development. Its rescue practice covers stalled or delayed projects, code stabilization, functionality extensions, technical audits, and decisions between refactoring and rebuilding. Onix also has specific experience rescuing mobile applications, including projects that need to move from incomplete or unstable implementations toward a scalable production product.
Mobian provides mobile engineering and post-launch support for existing digital products. Its services cover iOS, Android, and Flutter development, legacy integration, bug fixes, scaling support, performance monitoring, and ongoing maintenance. The company also works with existing teams through dedicated engineering and team augmentation models, which can be useful when an organization needs additional expertise to recover or stabilize an application without replacing its entire development team.
Mobian specifically describes post-launch support as part of its delivery model, including bug warranty, performance monitoring, OS updates, scaling, and flexible maintenance packages.
CrecenTech provides mobile development with a dedicated Rescue & Rebuild capability for stalled and unstable applications.
