- Path 03It is out of date
Upgrading or modernizing
The app runs on the Legacy Architecture, an old version, Cordova or Ionic.

Cost and timing
What it costs and how long it takes
The review is free
A 60-minute architecture review of your React Native app setup, with a written plan you keep.
A fixed-scope proposal first
Before any work starts you get a written proposal: a fixed-scope project with milestones, or a monthly plan. You approve it, or you do not.
Timing follows scope
How long it takes depends on what is in scope. The proposal states the milestones, so you see the timeline before you commit.
