Be sure to view the support video. The ads for the "Lite" version don't seem too intrusive. What I think is a minor limitation is that the screen does not rotate into a landscape orientation, only into either of the two portrait views, so if the iPad is propped horizontally one needs to turn one's head or the iPad or just read the button labels sideways. The paid version eliminates the ads and appears to allow full rotation. ### 5/5 — Very cool *2010-11-29* I really this app. The calculator is very useful, and beautiful. I do separate calculations all the time and find myself always looking for a place to write the results to do more operations later. The memory feature in calculators is not my preference. Hence I find this calculator amazingly simple yet useful. Since it is just released, I hope updates keep coming. For instance, ability to choose if add all the individual results or do any other operation. Thank you so much --great idea. ## Frequently asked questions about Fusion Calculator for iPad Lite ### What devices does Fusion Calculator support?
