Remember FlexyCore DroidBooster? Well, the original 2010 demo app works fine to this day!

Back in 2010, a company known as FlexyCore developed a technology called DroidBooster that promised significantly snappier app performance even on low end devices. In one of their videos, they demoed a media app they optimized with DroidBooster running on an HTC Magic (based on a slow pre-Snapdragon Qualcomm SoC, running at 528MHz) in comparison to a Nexus One (based on the first Snapdragon, running at 1GHz) running the app without DroidBooster. The DroidBooster-ized Magic ran almost as well as the Nexus ran without DroidBooster! Anyways, Google bought DroidBooster later on. By some sheer luck, I've managed to find the APK for one of FlexyCore's early demos, specifically from the 15th of February 2010! Here are some pics of it working on my Galaxy Tab S3! Also, here is a link to where I've uploaded my copy:
