• Directory Customization
  Custom folder icons, cover images, and backgrounds in the tree and grid.
• Local-First & Private
  Works fully offline. No account, no telemetry. Files stay on your disk.

• Cross-platform code reuse
  Hiring React Native developers lets you build iOS and Android apps from a largely shared JavaScript codebase, which cuts development time and cost compared with building two separate native apps.
• Faster time to market
  Features such as hot reloading, reusable components and a large library ecosystem speed up development and iteration, so an MVP or product update can be released sooner.
• Dedicated, flexible engagement
  Agencies like Appsted typically offer dedicated developers on hourly, monthly or project-based models, so you can scale the team up or down without the overhead of recruiting and managing in-house staff.
• Access to pre-vetted expertise
  Hiring through an agency gives you developers who already have experience with React Native, API integration, third-party services and app store deployment, which reduces the risk and time of screening individual candidates.
• Near-native performance and UX
  React Native renders using native components, so apps generally feel smooth and look consistent with platform conventions, and they can still be extended with native modules when needed.

Possible disadvantages

• Limited transparency on pricing
  The page does not clearly list fixed rates or detailed pricing, so you have to request a quote and cannot easily compare costs with other providers upfront.
• Performance limits for heavy apps
  Apps that need intensive graphics, complex animations or deep hardware access may still require fully native code, which can reduce the cost and speed advantages of React Native.
• Dependence on third-party libraries
  Some features rely on community packages that may be poorly maintained or lag behind new iOS and Android releases, which can cause bugs, compatibility issues and extra maintenance work.
• Outsourcing communication challenges
  Working with an external agency, possibly in a different time zone, can lead to communication gaps, slower feedback loops and less control over day-to-day work than an in-house team.
• Vendor lock-in and knowledge transfer risk
  Relying on an agency for development means that code ownership, documentation and handover need to be clearly defined, or you may struggle to maintain or move the app to another team later.
