Review on Draw.io by Warrick Infinite

It's easy to use - no learning curve required! I can create flowcharts in minutes without needing any technical knowledge or design experience at all (although it does have some nice features). The export function could be improved though; sometimes you want something that isn't available from other tools out there like FlowDroid by Google/Amazon etc., but this one has everything we need with just few clicks of button away. Our sales team uses these diagrams every day so they are very helpful when presenting our customers' products via presentations & meetings too which saves us time since we don't spend much effort creating them ourselves anymore because their designs were already done before hand thanks to drawing programs such as Adobe Illustrator / Photoshop along with free web-based ones. We also send those drawings over email using Gmail app instead.
