I have been using this app for a few weeks now and I’m really thrilled. It has all the capabilities of other apps that I’ve used & more with the journal feature really being useful. The interface is really intuitive and it has a bunch of recipes preloaded into it, which are great. Additionally, there’s access to the data sheets from the chemistry manufacturers, which is really helpful for the reference. Definitely recommend this app.
