Frequently asked questions
Is Iron Tuna really free?
Yes. Custom auction values for your exact league and scoring are free with no signup. The Advanced Auction Day Assistance package is the paid upgrade.
Does it work for any auction league?
Any auction league. Set your teams, budget, roster, and full custom scoring, and every value recalibrates to your exact settings.
How is it different from other tools?
Most tools hand you one generic auction value. Iron Tuna gives three numbers per player — market price, true value, and your personal max — plus an AI navigator that tells you exactly how high to go in real time.
Will it work on draft night?
Yes. It runs entirely in your browser and keeps working even if the Wi-Fi drops.
