Winner21 App (赢家) is a free horseracing app developed by Pioneers Leaders Publishers Pte Ltd for Android users. The app provides accurate and up-to-date horseracing information and statistics for races in Singapore, Malaysia, Hong Kong, Macau, Korea, Australia, and South Africa. With a 40-year history in the horseracing industry, the app offers a range of features to assist users in selecting the strongest horses.

The app's computerized horse-picking algorithm, proprietary iformrate, and 3-star rating system provide users with the tools to select the best horses. Additionally, users can analyze the performance of thoroughbreds with post-race videos. The app also provides race results for selected venues within minutes of the last horse past the post, and dividends/payouts are shown in the local currency of the race venue. Users can view the race card as well as the records of the horse, jockey, and trainer at one glance, making it easier to make informed decisions.
