RiverLab is a free, no-login poker education tool for practicing turn call/fold decisions. It combines an exact clean-outs calculator with 12 reviewed drills that show hit probability, required equity, and direct-showdown call EV. Progress stays on the learner’s device. It is deliberately narrow—not a solver, not GTO advice, and not a promise of winning.

I built RiverLab around one poker study problem: players often know what a draw is but still struggle to compare its chance of hitting with the price they are being offered. I wanted the answer to be auditable instead of hidden behind solver authority.
The first release is intentionally focused. It includes a free clean-outs calculator and 12 reviewed turn decisions. Every answer shows the hit probability, required equity, and direct-showdown call EV, with the assumptions made explicit. No account is required, and learning progress stays on the device.
I would value specific feedback on confusing wording, questionable assumptions, or anything that appears mathematically wrong. RiverLab does not model ranges, rake, ties, dirty outs, or future betting, so those limitations are part of the product rather than something I want to hide.

Took the turn drills last night and the direct-showdown EV readout really clicked for me, way more useful than another equity calc. Love that nothing leaves my device.

Thanks, Suat — that comparison is exactly what RiverLab is trying to make clear. I’m glad the direct-showdown EV readout helped, and keeping progress on-device was an intentional privacy choice. If any drill wording or assumption felt unclear, I’d really value the specifics.

Love how the clean-outs calculator makes the math obvious without dumping a wall of theory on you. The direct-showdown call EV on the drills is genuinely useful for someone trying to clean up turn leaks.
