Frequently asked questions

How to join the Zepp OS community?

Join our Discord community (https://zeppos.dev/discord).

How do I get started if I have no Zepp OS development experience?

Discord -> 💡tutorials
Follow Zepp OS documentation and start by creating Mini-programs or workout extensions based on the sample v3 template.

What if I don’t have an idea?

Join the community (Discord -> #🤝looking-for-team channel) and discuss product design with experts to receive suggestions.

How do I test if I don’t have a smartwatch?

It’s recommended to start testing with the simulator. Zepp Health staff can assist with testing.

Is team participation limited?

There are no limits on team size or participation. Awards are granted per project rather than per individual. For example, if Team A — with three members — submits an app and wins the Gold Award in the Smartwatch Connectivity category, the team will receive one Amazfit T-Rex 3 Pro and a $300 gift card. Team members may divide the prize as they wish (e.g., $100 each or $150/$150), ensuring no single person is solely responsible for managing the funds.

Prize Distribution for Gift Cards:

The competition organizer will attempt to purchase gift cards supported in your country to ensure that prizes can be distributed to the winners, which will usually be Amazon Gift Cards or Prepaid VISA Cards.
