Comments on Black Hole Finder for Android

★★★★★ Gerry Sherlock · May 31, 2025
I love this app, and thoroughly applaud this initiative which is looking for star brightening or dimming as a sign of a black hole transient. The training is in the app and we folks get to help with real science and evaluate images. If you get to be a superuser you even get to request follow-ups on one of the large telescopes attached to the program. I have done over 30 evaluations, so I must be hooked!
★★★★☆ Henk Langeveld · May 13, 2026
Nice and quiet app for killing time in-between with little distractions. Could be improved. 1. Default to Classify after first use. 2. Training mode - use historical examples and let people make their own mistakes. The tutorial only shows examples. 3. Better guidance on dealing with large (>10px) bright blobs. What's the size of a pixel if some pictures are blown up? 4. Add additional hairlines in red or green at the edges of square one, to better identify the object at the center.
★★★★★ Winstone Jordaan · Aug 24, 2024
As a software developer, I would like some sort of app access, that I can write my own automated classification. Is this an option?
★★☆☆☆ Nirmala · Jan 13, 2025
