Who Heater is for
Heater is not for people looking to get rich at the casino. Card counting works, but the edge is small and variance is brutal. Heater is a learning tool, not a shortcut.

The grinder
You count already but want to stay sharp between casino sessions. Practice mode and Full Shoe Simulation keep your mechanics tight.
The curious
You want to understand the math behind blackjack. The free tier lets you explore counting without commitment.
Free or Pro

Pro unlocks everything for $9.99/month or $79.99/year — unlimited practice, Advanced Practice mode with Illustrious 18 deviations, Full Shoe Simulation, Deal-Along, focused drills, table rules customization, and all 49 achievements. 3-day free trial. Cancel anytime in iOS Settings.
Heater is an educational and analytical tool. Card counting is not illegal in most places, but casinos can refuse service, ban players, or void winnings online. Using a phone or device at a live blackjack table is prohibited in many jurisdictions, including Nevada under NRS 465.075. You are responsible for knowing the laws and venue rules where you play. 18+ only.
