As soon as I opened the app, a video ad the full size of my phone's screen was running. This totally surprised me and made me wary of this app. If the author of the app stops the ads and states so on his Apple App Store page, I would consider redownloading the app and trying it again. ### 5/5 — Very good application *2017-01-06* This is very good application. This is really free. ### 1/5 — Very limited *2014-07-31* Only a few constants are included. Also annoying ads - not mentioned in the description. ## Frequently asked questions about Physical Constants ### What is Physical Constants - ML?
