GTO Ranges+ is a preflop range app for iPhone and iPad covering multiway spots — 2 to 9 players, not just heads-up. Look up the GTO-optimal play for any position, stack depth, and action sequence in seconds, then drill it until it's automatic. Over 200 solver-computed preflop spots across MTTs, ICM, PKO, cash games, and Spin & Go, with exact frequencies for fold, call, raise, and all-in across every combo. Download spots for offline study — on a plane, at a live event, anywhere with no signal. WHY MULTIWAY PREFLOP IS HARD Most preflop tools solve heads-up spots and leave you to guess when three or more players are live. But multiway is where tournaments are decided: the button opens, the small blind calls, and now you're in the big blind with a decision no heads-up chart covers. Every extra player changes the equities, the sizing, and the calling range. GTO Ranges+ gives you the solved answer for 2 to 9 players instead of an approximation. WHAT'S COVERED • MTT — Chip EV (81 spots), ICM (50 spots), PKO (18 spots), from early levels to the final table bubble, including sims calibrated to real tournament structures • Cash games — online 6-max and 9-max (15 spots), heads-up (3 spots), live ante games, at NL50, NL500, NL50GG, and NL1KGG rake levels, classic and ante formats • Spin & Go — 60 spots covering 3-max hyper-turbo dynamics WHO IT'S FOR • Tournament grinders working on multiway preflop in MTTs, PKOs, and ICM-heavy final tables • Cash players studying solved multiway ranges at their exact format and rake level • Spin & Go specialists who need 3-max ranges at every stack depth • Coaches and stables who want consistent solver-verified ranges plus their own custom sims FEATURES • Range Lookup — any spot by format, player count, rake level, type, and stack size classification per position • Targeted Drills — pre-packaged scenarios for Defending BB, Facing 3-Bets in and out of position, Blind vs Blind, and more • Streak and EV Tracking — accuracy streak, GTO score, session EV loss, and per-hand feedback in real time • Offline Downloads — download any spot pack and study with no connection • Upload Your Own Sims — import HRC sims for custom training, built for coaches, stables, and study groups Part of the ThinkGTO poker training suite, alongside Solver+, Postflop+, Preflop+, and PLO+ — used by over 15,000 active players.
