# Code review for mobile

> Mobile is where review tooling broke first — phone screens, swipe-friendly diffs, async patterns.

**Sector**: [Developer Tools](https://signals.gitdealflow.com/niche-down/developer-tools)  
**Build cost**: Month-long build  
**Deal velocity**: Steady — one deal per month

## Why now

Async + distributed teams created a real need to triage PRs from a phone. GitHub mobile is read-only; the gap is real.

## What the signal looks like

Repos that publish iOS / Android binaries on every release and treat the web UI as secondary. Star growth dominated by managers and senior ICs, not juniors.

## Public examples

*Public projects + categories only — we never name founders tracked inside the paid product.*

- Pull request triage apps with native mobile clients
- Code review apps shipped via TestFlight + Play Store
- Slack-bot-first review flows for mobile-first managers

## What this displaces

GitHub mobile + a Slack notification + 'I'll look at this when I'm at my laptop.'

## Our build-vs-invest call

Wedge product is the mobile reviewer. Eventually expands to standups, deploy approvals, on-call. Build if you ship native mobile fast. Invest if you watch a repo gain stars from engineering managers (high LinkedIn-bio match rate).

## Frequently asked

### Isn't GitHub going to ship this themselves?

They had years to. They didn't. The constraint is product focus, not capability.

### What's the GTM?

Bottom-up to managers in async-first companies. Top-down to platform teams in larger orgs.

### How fast can this category grow?

Slowly — but the LTV is high. Once a manager replaces their workflow, switching cost is months.
