Horse Racing Prediction SNS App [Umarkle]
~ Post and share your horse racing predictions with just a tap of your finger! A horse racing community where everyone's predictions gather ~

What is the Umarkle app?

Umarkle is a new kind of horse racing prediction SNS app where horse racing fans can easily post, share, and analyze their predictions.

From beginners to veterans, bloodline enthusiasts, training enthusiasts, and race development enthusiasts, we provide a platform where all horse racing fans can experience horse racing predictions "more conveniently and more enjoyably."

From JRA (Japan Racing Association) G1 and graded races to other featured races, quickly express your top pick (◎), betting selections, and race development predictions with just a tap of your finger!

Compare everyone's predictions all in one place and use them to help with your weekend betting and race predictions!

[A New Horse Racing Prediction Experience Proposed by Umarkle]

Traditional horse racing newspapers and general social media platforms presented several challenges: "It's difficult to compare which horses others are picking at a glance," "It's hard to neatly organize and save your past predictions and reasoning," and "It's difficult to find people with similar prediction styles."

Umarkle is a dedicated horse racing social media app created to solve all these problems.

With its sophisticated and intuitive UI design, you can smoothly complete everything from sending prediction marks to creating detailed race diagrams, writing detailed analysis notes, and organizing your betting selections. Posted predictions are automatically organized and visualized, making it easy to compare and share with other users. It provides a community where horse racing fans respect each other's predictions, making weekend races many times more enjoyable.

[Key Features of Umarkle]

◆Easy with just a fingertip! Authentic Prediction Posting
You can easily create and post predictions with intuitive controls, including inputting prediction symbols such as "favorite" (◎) and "second choice" (○), a race development forecast that visualizes the overall race development, prediction notes (analysis) where you can write down your reasons for your favorite and race trends, and a betting selection function to organize your specific bets. Clearly articulate and visualize your prediction stance and deciding factors.

◆ Compare everyone's prediction symbols at a glance with "My List"!

Prediction symbols from your favorite users and friends are neatly displayed in a single comparison table screen for each race!

"Who is everyone's favorite horse (◎) in this race?" "How are the second choice (○) and long shots (☆) divided?" is immediately clear. It's easier to read than newspapers or message boards, and you can quickly incorporate perspectives other than your own.

◆ Three Timelines to Choose From Based on Your Purpose
"Discover" Tab: Carefully selected high-quality posts with detailed prediction content, race development forecasts, and prediction notes. Ideal for those who want to check in-depth analysis and race development forecasts!

"Trends" Tab: Quickly discover posts from popular users currently attracting attention, and users with recent high success rates and return rates!

"Following" Tab: Stay up-to-date with the latest posts from your following horse racing friends and tipsters.

◆ "Tag Function" & "Powerful Filtering Search"
You can freely set tags on prediction posts such as "Training," "Track Condition," "Paddock," "Race Development," "Jockey," "Suitability," "Performance," "Pedigree," "Race Trends," "Intuition," "Odds Value," and "Longshot."

You can freely search to see only predictions for specific horses or jockeys, filter to bloodline-based predictions, or refer to the views of those targeting longshots! Instantly access the horse racing data and prediction approaches you need.

◆ Compete in prediction skills with our unique "Ranking" system!

The accuracy and success rate of submitted predictions are rated using our unique logic!

The fun of competing expands as you aim for the top of the rankings to prove your prediction skills, or follow top-ranked handicappers to use their insights for betting.

◆Connect and Expand with "SNS Integration and Communication"
・Instant Share to SNS (X, etc.): Easily share your prediction marks and images on a race-by-race basis to various SNS platforms!

・Reaction Function: Celebrate great predictions from friends and other users with "Likes"!

・PUSH Notification Function: Receive timely notifications when a user follows you or when your posts receive "Likes".

・QR Code Integration: Instantly follow and connect with other horse racing enthusiasts using QR codes!

【Detailed Features and Ease of Use】

A Race Development Prediction Tool that Visually Illustrates Race Development
You can move and position each horse using drag-and-drop functionality from the horse number pool displayed at the bottom of the screen.
Because you can visualize the positioning of horses at four key phases—"after the start," "backstretch," "final corner," and "before the finish line"—you can perfectly express and visualize the race development in your mind, including the assertiveness of the front-running horse, the pace of the leading group, and the paths taken by horses coming from behind.

Betting function to support the number of bets and fund management: Supports win, place, quinella, exacta, trifecta, superfecta, and quinella bets. Simply specify the key horse and opposing horses, enter the number of bets for each type, and enter the planned purchase amount, and the total amount will be calculated automatically. Betting formations and combinations are neatly organized, making it extremely useful for post-race review and fund management.

Unique stamp function: In addition to "winning stamps" and "high payout stamps" based on race results, we also offer a "loss stamp" for when you narrowly missed a win (a situation where you won but still lost money)!

[Recommended for these types of people and horse racing fans!] 】

* For those who want to manage, record, and post their horse racing predictions more conveniently.
* For those who want to refer to other horse racing fans' favorite horses, long shots, betting selections, and reasoning.
* For those who want to know "everyone's race development predictions and views" that can't be seen from just horse racing newspapers and odds.
* For those who want to share their preferred prediction style, such as bloodline, race development, training, and race trends.
* For those who want to test their prediction skills in a ranking and improve their race hit rate and return rate.
* For those who want to share weekend horse racing predictions (G1, graded races, etc.) on social media (X, etc.) and get excited with friends.
* For those looking for a horse racing app/betting memo tool that is easy for beginners to understand and operate intuitively.

【Umarkle Usage Methods by Prediction Style】

* Training-focused and Track-focused Usage Methods
Consider the advantages and disadvantages of training times, movement on the uphill track, and the track condition on the day (good, slightly heavy, heavy, poor), and post with the tags "training" and "track." You can share sharp predictions that focus on good track conditions.

* **How ​​to Use for Race Development Analysts and Forecasters:** Using a four-phase race development diagram from the start to the finish line, you can visually explain the race pace (high pace/slow pace) and positioning. This allows you to intuitively convey the logic of race development that is difficult to explain with words alone.

* **How ​​to Use for Odds Value and Longshot Bettors:** When you find a horse with favorable win or place odds, or a talented horse that's overlooked by the popular vote, tag it with "Odds Value" or "Longshot Bet" and share it. You can gather enthusiastic support from fellow bettors aiming for high payouts.

* **How ​​to Use for Beginners and Casual Fans:** Initially, check popular posts in the "Discover" or "Trends" tabs. You can use "My List" to see horses that many horse racing fans have listed as their favorites (◎) or contenders (○), and use it as a guide to build your own predictions.
