Welcome to the latest installment of FanGraphs Changelog, where we update you on some of the recent improvements we’ve made to the site as we work to build a better FanGraphs.

First, a few things you might know about already:

• We updated the Baseball Simulator to include a bunch more features, including historical players and park and weather factors.
• We launched the RosterResource Roster Grid.

App Updates!

We’ve added The Board to the FanGraphs mobile app, which can be download here: App Store (iOS) or Play Store (Android).

In adding prospects to the app, we’ve outgrown the bottom tab bar, so you can now select between a few preset tab bar configurations; Members can fully customize the tab bar. To customize the tabs, go to the More Menu and select “Customize Tabs.” As a reminder, all features in the app can be found within the More Menu.

We’ve also implemented a new Member feature that allows users to set their default player page view options, while also allowing for temporary changes:

One of the challenges of fitting a data-intensive website into a mobile app is figuring out how to allow users to view the ever-growing number of tables they want to see. For example, I might have default tables that I typically look at for a given player (in the image above, it’s the Standard table), but today I need to see that player’s wRC+, WAR and Win Probably Added to settle a debate with a friend. Using the Temporary view option, I can temporarily enable the tables to see those stats. The next time I use the app, however, it will reset to the default view that I’m used to.

We’ve also implemented push notifications for both Android and iOS. After enabling notifications at the OS level, you can find the main controls for the notifications in the More Menu under “Notifications.” There you can choose to follow updates based on a scoring change in a selected team’s game, see when that team’s game goes final, or both:

If you are using iOS, you can enable Live Activities within the Scores tab to follow a live updating Win Expectancy Graph on your lock screen. Note that iOS limits Live Activities to five at a time:

You can also get a notification when we publish a new article, or follow a writer by tapping the subscribe (bell) button on their byline. Note that co- and tri-bylines are considered distinct from individual authors:

You can also now submit feedback directly in the app to report a bug or request new features:

RosterResource Contracts on Player Pages

Last month, Jon Becker added player contract details to the RosterResource Payroll pages. We’ve now integrated that feature into the player pages. If you go to a player page, find the RosterResource section on the side bar, and click Contract History, you can find the contract history for the player contracts we have tracked since 2020, when we integrated RosterResource into FanGraphs:

We’ve also upgraded the Closer Depth Charts to include more information about a given appearance, including how many innings the pitcher pitched, which innings they pitched, the number of batters they faced, and the leverage when they entered the game:

Legacy Team Usage Lineup/Def

We’ve moved the two player usage tools — Batting Lineups and Defensive Lineups — from the team pages into RosterResource:

These offer different views than the Lineup Tracker, showing the batting and defensive lineups vertically. The “row banding” allows you to see usage streaks more easily.

Flair

We’ve continued expanding our customization options for Members. We wanted to do a black header to go with our Dark Mode, which might have been inspired by some of the recent City Connect uniforms. But unlike the City Connects, the header and theme is totally up to you, the FanGraphs Member!

If you have any questions, please leave them in the comments below, and if you have any suggestions for site features, please be sure to let us know. And lastly, a thank you to our Members! Membership is the best way to support our staff, and ensure that we can continue to grow and improve the site. We couldn’t do any of this without you!
