What are the Best DFS Apps?
It’s no secret that DraftKings and FanDuel helped pave the way for the daily fantasy sports industry that we know today. However, the evolution of DFS sites like PrizePicks, Underdog Fantasy and Sleeper Fantasy have managed to carve out a niche in the competitive DFS industry and attract a loyal player base by offering a fresh take on traditional DFS contests.
Stokastic is bringing our top-tier projections to the pick’em scene! With a Pick’em package, you’ll gain access to our elite PrizePicks, Underdog and DraftKings Pick6 Optimizers, making it effortless to build +EV entries in just a few clicks. If you’re a pick’em enthusiast ready to dive in, our tools and data provide unmatched value.
- PrizePicks: PrizePicks is a unique DFS site that allows players to make more/less predictions on the statistical performance of individual players. Unlike traditional DFS platforms, where players must build a lineup, PrizePicks only requires you to select a few players and predict their performance in various statistical categories. This unique gameplay format has attracted players seeking a simpler and more streamlined DFS experience that more closely resembles sports betting.
- Underdog Fantasy: Underdog Fantasy is a DFS site primarily focusing on best ball contests for football and basketball. In best ball contests, players draft a roster of players but do not have to make any lineup decisions throughout the season. The platform also offers traditional DFS contests and unique formats like pick’em contests and snake drafts. Underdog Fantasy has gained popularity due to its innovative gameplay formats and engaging user experience.
- Sleeper Fantasy: Sleeper is a fantasy sports platform that offers a variety of games, including fantasy football, basketball, and esports. Sleeper Fantasy app offers exciting new features and enhancements, including the opportunity to win up to 100x your entry fee, in-game contests, and dynamic payouts. Dynamic payouts introduce multipliers attached to player projections, replacing pre-set multipliers based on contest size. Additionally, Sleeper now supports a broader range of stat categories, allowing contests in areas like MLB home runs, triples, stolen bases, and NBA double-doubles and triple-doubles.
