Escalafy works fully from your phone: the web app is 100% mobile-friendly.
You can go straight to app.escalafy.com from your phone's browser and use the dashboard, costs, integrations and reports as usual.
If your numbers look different on your phone and on your computer, check the currency selector at the top right: it's common to have it set to USD on one device and to pesos on the other. That selector only changes the display and doesn't modify any settings.
