Is there an Apple Watch app?

Yes, for iPhone with an Apple Watch on watchOS 26 or later. It installs automatically if Automatic App Install is on; otherwise open the Watch app on your iPhone, find WitnessWork under Available Apps, and tap Install. Then open WitnessWork on your iPhone once so your watch gets your progress. The watch shows this month's hours and whether you're ahead of or behind your plans, counted the same way as on your iPhone (without plans, how much a day it takes to reach your goal). On the watch you can add time for today with an optional Type, start and pause your iPhone's timer, and save the timer's time as an entry. If you don't log hours as a Kingdom Publisher, you can mark that you shared the good news this month. Two complications can go on a watch face or in your Smart Stack: Monthly Progress shows your hours toward this month's goal, with a mark where your plans put you by today; in a round spot you can choose a ring or a gauge, with your goal at its end or a clock below, and without a goal it shows your hours alone. Up Next shows your next follow-up or plan. You can also use Siri on your watch to add time, start, pause or stop your timer, and log a mileage trip, with the same phrases as on iPhone, such as "Add time in WitnessWork" or "Log a trip in WitnessWork". Your iPhone keeps your records. The watch receives your monthly progress, report status, timer, Types, car names and distance unit, and for Up Next the name, address and topic of your follow-ups and the title and place of your plans for the next two weeks. It never receives notes or other contact details, and it can't edit or delete entries. The watch app needs your iPhone, so it isn't available for an Apple Watch set up with Family Setup. With an Android phone, use the Wear OS app instead.
