Rithmm is the most app-first AI betting tool we have tested, and its custom model builder is genuinely different from the pack. Our verdict: if you bet player props on US sports from your phone, Rithmm is one of the best picks in 2026 — provided you treat its models as a tool, not a guarantee. Here is the full review.
What is Rithmm?
Rithmm is a mobile-first AI sports betting app (iOS, Android and web) that surfaces daily picks across NFL, NBA, WNBA, MLB, college basketball, college football and golf. Its signature feature is a custom model builder that lets you weight the stats you care about and generate your own player-prop and game-line predictions.
Features: custom models and player props
Rithmm’s standout is the build-your-own-model tool, paired with deep player-prop predictions — an area many rivals ignore. You also get game predictions, line comparison, player-adjustment tools and “smart signals,” all wrapped in a polished app experience.

Pros, cons and our verdict
Rithmm is best for US sports bettors — especially player-prop players — who want a powerful mobile app and the ability to build custom models. The main gaps are no soccer coverage and premium pricing that climbs quickly. If you mainly bet football (soccer), it is not the right tool.
Rithmm’s custom models are a smart way to engage with the data, but remember a model is only as good as your inputs — our guide to AI win rates and accuracy claims explains how to judge results honestly.
