User Reviews

As others have said, the app does not work with yahoo when its marketing suggests it does. In fact, it only works with espn and sleeper. The Developer’s response to other reviews regarding this is “it’ll be fixed very soon”. When is very soon? Share your roadmap with your subscribers, commit to a date, and UPDATE YOUR MARKETING to reflect reality so you aren’t misleading people. The app is poor in other ways too. Start/sit and waiver suggestions aren’t insightful. Recommendations are basically “Start player A over player B because they have a higher ceiling and are projected to score more fantasy points”. No in depth analysis of each player’s matchup or anything like that. Just “we think they’ll score more points”. Also, it doesn’t actually synch or live update. The first game of the season just happened last night and the app is still suggesting that I sit players who have already played. The players’ scores in Flex still show projections even though they have already played. Flex also won’t “push” start/sit decisions to your fantasy platform. If flex suggests you start player A and sit player B, you still have to go into your fantasy league platform, make the changes, and then go back into flex to tell it whether or not you did so. The AI that drives the analysis is weak, (probably just scraping data from other subscription platforms and presenting it as their own) and functionality is very limited. Clearly somebody just used AI agents to rapidly build an app and rush it to market before the season started with a teaser $.99 founder subscription. Its not even worth that and its not worth your time if you value your time at all. If the developer’s response to this review is similar to those that were published before mine, you’ll know that their AI customer service agent is as poorly trained as the ones used to build the app and run the marketing.
