I use this application almost everyday at work, from planning for training to operational incidents. ### 5/5 — Great product *2015-11-11, version 1.0.64* Chemdata is a great product for all those in the emergency response world. We use it regularly alongside the chemsafe scheme. ### 2/5 — A 'Must Have', but the subscription is normally £975 per year *2015-02-23, version 1.0.53* You need to be transparent about how much your information actually costs. There is no price for a subscription in the description and the app is woefully limited without it. You did offer a discount for my profession to £500 per year but I am afraid this is still far too much for an occasional use app. Toxbase, one example, similar database for poisons has a £6 subscription per year for NHS staff. ## Frequently asked questions about Chemdata ### What is Chemdata?
