GTO Poker Preflop Range Charts

RangeLens is a GTO poker trainer and study app for Texas Hold'em. Preflop range charts, postflop solver spots and a live hand walkthrough that answers the spot you are actually in, and tells you why.

PREFLOP RANGE CHARTS
Open, 3-bet, 4-bet and calling ranges by position and stack depth, laid out on a hand grid. Your hand is highlighted inside the range, and borderline hands are marked as borderline instead of being rounded into a yes or a no. A preflop chart you can reason from, not just memorise.

POSTFLOP SOLVER SPOTS
Flop and turn spots with action frequencies for every bet size. How often the strategy checks, bets or raises, which sizings show up, and what the range is doing as a whole. Every recommendation carries its source, so you always know whether you are looking at a GTO solver output or a chart baseline.

LIVE HAND WALKTHROUGH
Enter the hand you are playing, one street at a time. RangeLens gives you the action for each street with the reasoning behind it, in a form you can read in the time you have at the table.

ODDS AND EQUITY CALCULATOR
Hand vs hand and hand vs range equity, outs, pot odds and the equity you need to call. Poker hand rankings are built in for quick reference.

ICM FOR TOURNAMENTS
Final table and bubble spots priced in prize money instead of chips, so you can see where chip EV and real EV pull apart.

HAND REVIEW
Reopen a finished hand and see the street where it went wrong. Repeated leaks show up as a pattern instead of a feeling.

HOW PEOPLE USE IT
1. Look up one spot you keep running into in the preflop range charts.
2. Open the same spot in the postflop solver spots and read the frequencies by size.
3. When it comes up at the table, walk the hand through street by street.
4. Review the finished hand afterwards. One spot a day is enough.

WHO IT IS FOR
- Players who want preflop ranges as a standard, not a guess
- Players whose postflop sizing changes every session
- Anyone starting poker study who does not know what to look at first
- Players who want poker strategy in their own language (33 supported)
