Can I run on it or only walk?

It is designed for walking and light jogging. The flat deck and lack of handrails make fast running awkward, so treat it as a walking pad with some jogging headroom.

Do I need the app to use it?

No. The belt runs without a phone. The SunnyFit app adds step, distance and calorie tracking, trainer workouts and virtual routes, and Kinomap adds interactive routes.

Does it have incline?

No. The deck is flat, so resistance comes only from your pace and any settings on the belt.

Will it fit under a standing desk?

Its slim, low-profile frame is made to slide under a desk or bed. Check your desk's clearance height and the deck's footprint before buying.

The treadmill and the parts needed for assembly. The SunnyFit app is a free download; a phone or tablet is not included.

How is it different from a full treadmill?

It has no handrails or incline and a smaller motor, in exchange for a much smaller footprint and easier storage. A full treadmill gives more stability and speed for running.
