I recently purchased a Rocketbook Everlast, which is a reuseable notebook that can be written on, scanned with a cell phone using the Rocketbook app, and then erased with a damp cloth. It’s like having a portable whiteboard, except that it looks and feels like a notebook, and the integrated app makes scanning and organizing notes very easy. I’ll eventually write a detailed review on it, but for now I wanted to share my experience with changing the Rocketbook app’s resolution setting.
(Note: This only applies to the Android version of the app; the iOS version does not allow the resolution to be changed. See the RocketBook FAQ for more details.)
The app defaulted to a resolution of 2592 x 1944, which is only 5MP. My phone (a Moto G4 Play) has an 8MP camera, so I changed the setting to 3264 x 2448 to match it. Here are samples of a page I scanned at both 5MP and 8MP (click to see full-size):
For both sample images, I attempted as best I could to shoot from the same angle and distance. I then exported to PDF and viewed them at 300% zoom for the full-size sample images. The image taken at higher resolution is noticeably smoother, as expected. It doesn’t make a huge difference, especially when viewing at a normal zoom level. But it’s still quite noticeable.
Based on my results, I think it’s well worth it to check this setting after installing the app and see if you can increase the resolution. It’s found by clicking on the gear icon at the top left of the app and then going to Advanced Settings. It only takes a minute and can really improve the quality of your Rocketbook scans!
