We built a CLI that scans your iOS app against every App Store guideline before you submit.
and now we gave it a cloud device so it can validate full user flows.
It checks for:
- Payment & IAP compliance
- Privacy manifests & data usage declarations
- Required sign-in & account management flows
- App completeness & metadata quality
- Binary & privacy-manifest validation
Made it a Claude Code and Codex skill so it fixes every issue for you. Scan, fix, repeat until passing

We’re bringing the magic of Waymo to Toronto! 🇨🇦
In the coming days, you’ll begin seeing Waymo’s all-electric vehicles driving through Toronto’s streets as we lay the groundwork for our ride-hailing service.
Our goal is to begin serving riders in 2028.

At Revyl, we work with mobile apps where understanding the sequence of actions, taps, transitions, loading states, bugs, matters just as much as understanding any individual frame.
We’ve been testing Gemini’s new agentic video understanding capabilities, and this is the part that’s exciting to us: giving agents the ability to reason over an entire interaction, not just isolated screenshots.
Really excited to see @Google pushing this forward, and to be part of the launch!

🗣️📢 calling all mobile designers
we built a tool that lets you edit UI directly in the app instead of going through Figma + engineering
1. select the part of the app you want to change
2. describe what you want
3. Cursor edits the code
4. review the PR
designers can make small UI changes without waiting on an engineer, and engineers don’t have to spend time translating tiny design tweaks into code.
I would rather occasionally get hurt while fully participating in my life than spend my life successfully avoiding everything that could hurt me.
AI can write a 10,000-line PR in minutes. Reviewing it still takes you an afternoon.
Introducing Revyl Bot:
It builds the app, tests the flows, and leaves screenshots + proof directly on the PR.
Engineers should engineer, let Revyl handle the proof.
this genuinely game changing
This is going to change mobile development forever.
Introducing Revyl Mobile Cloud Agents:
> Go to any screen in your app
> Write out any change you want to be made
> Get a full PR created with screenshots + proof the change was implemented
The agent handles everything between idea → code → testing → PR.
