The currency conversion is an example: too much work to scroll through the whole alphabet to find USD for example, and then another currency to convert. Want to switch? Same again. Maybe a text box to quickly jump to whatever currency? There’s the ability to work with a calculator, which is the main reason I wanted this, but it’s not intuitive as to how to do that –which makes it not really useful. I know I could eventually make this work, but right now I don’t have time to make the effort to train myself to use all the hidden features. One day maybe. ### 1/5 — App not working at all *2022-12-24* Not sure what’s wrong. Nothing is working and I’ll be asking for a refund. ### 5/5 — Great coffee ratio calculator *2021-01-27* This is the perfect app for finding how many grams of coffee you need for the ratio you desire when you are thinking in ounces. So you want to make 12 oz of coffee using a 1:15 ratio. Simply enter 12 oz and see the number of grams it equals then press on the gram quantity and it will switch to the calculator mode and all you have to do is enter your desired ratio number. Of course you only need to do this if you are use to thinking in oz. if you think metric you do not Ned to convert. ### 5/5 — Freaked love this app *2015-10-31* Settles arguments that's for sure! ## Frequently asked questions about Calvertr Lite ### What is Calvertr Lite?
