Re-indexes every time

My iPhone has a large photo library, around 140,000 images.

Cluster says it will take about half an hour to index. I do something else on the phone and come back later, and it has to re-index.
It continually has to re-index, so I can't use it.

It's a very nice idea – wish I could use it.

Response from developer

Thanks for the feedback! Cluster indexes photos on each launch — previously indexed photos are automatically skipped. Indexing does not run in the background. When you see the counter start at 0 again, that’s progress for the remaining photos only, not a restart: for example, if 200 were indexed before, the next launch will show progress out of the remaining total (e.g., 0/139,800), not 0/140,000. It can look like a reset since the number resets to 0, but no work is being redone. Happy to look into ways to make that clearer in the UI — feel free to reach out at johndewey02003@gmail.com

FAQ

Does Cluster upload my photos anywhere?

No. All search and organization happens entirely on your device. Your photos and the index data never leave your iPhone, ensuring complete privacy.

The first time you open Cluster, it indexes your photo library once. This process can take a few minutes, depending on the total number of photos you have.
