How can I tell if I'm ahead or behind on my hour goal?

Open the Progress tab from the bottom bar. On the Month view, the report shows how much is left and how many days are left, and the line under it shows whether you're ahead or behind your plans. The Daily Pace card shows how much a day it takes to reach your goal; add it with Edit Cards if it isn't there. Pioneers can switch to the Year view, where the Service Year Pace chart shows how far ahead or behind your Annual Goal you are today, and each month's bar shows how that month did against its goal. The Year Pace card shows how much a month you need for the rest of the service year.
