What to drill first
Drill your first-in opens by position before anything else. Once you can recall which hands you open from each seat, move on to answering someone else’s open with a fold, a call or a 3-bet, and then to adjusting for the game and the players in it. Ranges also change with the stack depth, the number of players and the rake, so drill the preflop charts built for the game you play.
A chart tells you what to do in the exact spot it covers. The reason behind a hand, its strength and your position, is what lets you think through a spot the chart doesn’t show. Take king-ten offsuit.
On our six-handed opening range charts it folds under the gun and opens on the button. Poker Skill teaches it as an under-the-gun fold and gives the reason: from the first seat to act, the hand makes too many weak top pairs. With only the blinds left behind you on the button, the same hand is a raise.

How we compared
Each app was judged on what it drills, how it checks your answers, what it costs and where it runs. Poker Skill’s facts come from its store listings, the app itself and its training app page; the other four were read on their own sites and store listings in September 2026. The range examples come from our six-handed opening charts, and the fit lines are our judgment.
Frequently asked questions
How do you memorize preflop ranges?
Start from a default range for your exact game, because opening ranges change with the number of players, the stack depth and the rake. Then learn it one seat at a time: the position-first method in our guide to memorizing preflop ranges starts at the button, the widest seat, and takes hands away for each earlier seat.
Does GTO Wizard have preflop charts?
Yes. Its library holds solved preflop charts for cash games and tournaments, and its trainer drills them, with 100 preflop solutions and 10 trainer hands a day on the free plan. On GTO Wizard's cash plans, Starter's preflop set is the basic one without antes or straddles, and Premium at $79 a month billed yearly opens every preflop solution.
Is Preflop Wizard free?
It is free to download, and Preflop Wizard's site describes a free tier for core preflop drilling with AI coaching, though the store listings don't say what it includes. Its App Store plans cost $19.99 or $29.99 a month and $89.99 or $129.99 a year.
