### 2/5 — Nice start but…

*2026-06-03*

This app is cool and has potential but needs a couple things right away. First, how about some documentation? Trying to figure out how to use this on my own is just wasting my time. Second, buggy as heck. Can no longer get to the import area. Seems to be stuck on a develop module which I cannot exit. Think I’ll take it off my iPad until things get fixed. Sorry buddy. I want to like but needs fixing.

**Developer response:** Thank you for your honest feedback. I am sorry that you have issues with the app. I might have gotten too much into features and requests and skipped some quality steps. I’ll fix this in an upcoming version.

There are some tricky parts to talking to the cameras and doing this stuff, but with your feedback I might be able to fix things faster. You can send me some details about your issue and I can have a look.

Thanks for giving it a try, and I hope you’ll check back once the next update lands.

Daniel

A faster, cleaner X Sim Lab — built for iPad.

• Settings fixes: smooth skin, monochromatic color, D Range Priority, and
  noise reduction now fully read, applied, and saved back to camera slots
  — recipes round-trip without losing detail.
• Sidebar reorganised: store actions moved to the Edit tab next to
  Reset to Capture for a more natural flow.
• Save a camera recipe directly to your local library with one tap
  from the Presets tab.
• New frame mode: tap to wrap your image in a clean white border for a
  preview that feels print-ready.
• Reworked camera import with a fresh modal, faster thumbnails, and a
  smoother grid that scrolls forever without breaking a sweat.
• Smarter camera connection: clearer status, a deterministic mode probe,
  and friendly hints when your camera needs to switch to storage mode.
• Tidier dashboard and sidebar — less chrome, more of your photos.
• Hung camera operations now recover automatically instead of leaving
  the app stuck.
• Welcome screen up front explains what X Sim Lab does (and what it
  doesn't), so everyone starts on the same page.

Thanks for testing X Sim Lab. Bug reports and ideas are very welcome.
