Used to love it until the last update.

I’ve used Dr. Cleaner for quite a while and have installed it on my client’s computers to help them understand how they’re using apps and how it affects memory. I’ve found that after the latest update Dr. Cleaner does not accurately reflect the actual total memory in use. I’ve compared in real time to other memory programs like istat and memcleaner and have seen it report 25% less memory in use. I will start to see pinwheeling when istat reports memory is at 99% usage while Dr. Cleaner is reporting 70%.
