Quick verdict
Same workflow with more structure → ShipNative (contract-enforced consistency, backend included). Trade prompts for control → FlutterFlow. Technically comfortable → Bolt.new. Ceiling-free developer path → Expo + Claude Code.
1. ShipNative — same category, reliability-first architecture
The closest like-for-like: prompt (or screenshot) to React Native + Expo with live phone preview. The architectural difference shows up as apps grow: ShipNative generates from a structured data contract— schema, seeds, and screens derive from one source — so screen five agrees with screen one about what a “workout” is, instead of each generation reinventing the model. Practical effects: fewer fix-it prompts (which is what credit burn mostly is), and a backend (auth + database) that’s wired in and activated with a Go Live button rather than assembled afterward. Full head-to-head: ShipNative vs Rork.
2. FlutterFlow — trade prompts for control
Different philosophy: visual editor with AI assist, Flutter output. Slower to first draft, more deterministic at scale. Right if Rork’s generation felt too slot-machine and you’d rather place widgets.
3. Bolt.new — for the technically comfortable
Browser IDE, can do Expo with coaxing. You gain file-level control, you inherit the toolchain babysitting. More on that workflow in vibe coding a native mobile app.
4. Expo + Claude Code — the developer path
If you’ve learned enough React Native from reading generated code, a plain Expo template plus a coding agent is the ceiling-free option. It’s a different hobby, though.
