Frequently asked questions
Is there a mobile app?
Yes! Cruxly is mobile-first. Available for iOS and Android with native camera integration and offline support.
Does it work offline?
You can capture photos offline. They'll process when you reconnect. Perfect for areas with spotty wifi.
How's the camera quality compared to laptop scanners?
Modern phone cameras are excellent. Our OCR is optimized for mobile photos—handles the angles and lighting you get with a handheld shot.
Can I sync between devices?

What about battery usage?
Optimized for mobile. The OCR and AI processing happen on our servers, not your phone. Minimal battery impact.
