Era bom…

Antes era muito bom, mas de um tempo pra cá, toda vez que volta pr menu inicial ou faz qualquer coisa, aparece “atualizando” e demora para voltar. Perde-se muito tempo. E é totalmente desnecessário! Não precisa ficar atualizando a cada poucos segundos!

Only one calc at a time

Great resource, but app freezes if you use the app for more than one calculator. Get out of the app between each calculation.
