What's New in PocketOP

1.3.0

September 15, 2026

This version adds a live lens zoom preview. No new permissions or entitlements are required. What changed in 1.3.0: - A live lens zoom preview on the camera feed: switch between the field-of-view outline and a live zoom that previews each focal length and moves to the sharpest rear lens automatically. - More detailed screenshot annotations. - Additional improvements and fixes. General notes: - No login, no account, and no external server calls for core functionality. The database loads from CDN on first launch and is bundled in the app as a fallback. - The subscription (Pro, annual) unlocks the full database and the copy-spec feature. The free tier (four broadcast lenses and one PTZ camera) is fully functional, so the paywall and Pro features can be reached and tested directly.

A Must-Have for Broadcast Production

As a project manager for webinars and livestreams, I find this tool incredibly useful. Being able to quickly show clients realistic camera framing and perspectives before any gear is even on-site makes conversations so much easier and helps eliminate a lot of guesswork.

Response from developer

Thank you for this thoughtful review! Helping production teams align on framing before the shoot is exactly what PocketOP was built for. Great to hear it's making those conversations easier!
