BetFully, Inc. builds tools for daily fantasy sports players under the LineStar brand. Focused on lineup optimization and props, the company develops mobile apps that help users analyze contests, construct lineups, and test combinations quickly. The current portfolio on our site includes LineStar DFS & Props Optimizer, LineStar for DK, and LineStar for FD, reflecting a concentrated effort on the two largest U.S. DFS platforms.
The team positions itself as specialists in DFS analytics and workflow: their apps aggregate player projections, ownership models, and slate-specific filters so users can move from research to roster construction in fewer steps. They support both DraftKings and FanDuel users with separate apps tuned to each platform’s scoring and roster rules. Contact and support are available via [email protected], and more information can be found at https://www.linestarapp.com/.
While BetFully, Inc. keeps a narrow product focus, that specialization has allowed them to iterate quickly and respond to market needs such as prop-heavy slates and contest-format differences. Their presence on multiple app stores and continued updates indicate an active development cycle aimed at maintaining accuracy and usability for daily fantasy players of different experience levels.
