This app does a great job of taking into your league's customized setting into account. I also really like how in depth the research is for each player is relative to free options out there like ESPN or Yahoo which only give surface level knowledge.
With that said, there could be some improvements. While the app dynamically ranks available players based on league settings and ADP/EDP, I don't think it does a good job of taking into account replacement value of certain positions. For example, I was in a 14 person half PPR league - in rounds 2-3, the app was pushing top tier WRs and TEs - likely because they have higher point projections than the RBs available. However, the drop off in good RBs available following that round is A LOT more significant than it is for other positions. Ultimately, it would've been more wise to ignore the app and make sure you grab a reliable RB before heading into the later rounds.
Sure, you could adjust switch to the tier by position view but then you lose the holistic view of all players available, and when you're on the clock, it's tough to switch back and forth between views especially given the app seems to be quite prone to bugs.
Additionally, I found the rate my team tool at the end of the draft useless. Not only is it pretty generic, but how can 12 out of 14 teams in my league have a >60% chance of making playoffs... somehow the math doesn't check out. For this feature, I actually prefer Yahoo!'s version: yes it's generic but at least they stack rank the teams afterwards.
Overall, I like the app but in its current state I'm not sure it's worth the $5 price tag. There are free solutions out there like Boris Chen that offer smoother and more reliable functionality in a live draft. It also doesn't make sense to me that the charge another $5 each for their start/sit and trade tools. Seems unreasonable that those are not included.
