Quick answer: Rithmm is the most app-first AI betting tool we have tested — iOS, Android and web — with a custom model builder and deep player props across NFL, NBA, MLB, college sports and golf. A 7-day free trial then plans from ~$29.99/month. Best for US prop bettors who want control; it does not cover soccer.
Rithmm’s custom model builder is genuinely different from the pack. If you bet player props on US sports from your phone, it 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 in a polished app.

Rithmm pricing
Rithmm offers a 7-day free trial, then plans from around $29.99/month, with annual billing dropping the effective rate to roughly $19.99/month and a premium tier higher up. The free trial makes it low-risk to test whether the model builder fits how you bet.
A worked example: a Rithmm player prop
Rithmm’s strength is props. Imagine you build a model weighting usage and pace, and it projects a guard for 27.5 points while the sportsbook line sits at 24.5. Convert and compare: if the model implies a 60% chance of the over but the price implies 52%, that 8-point gap is the edge — the value logic in our expected value guide.
| Market | Line | Model projection | Edge |
|---|---|---|---|
| Points over/under | 24.5 | 27.5 (60% over) | Over, +8% vs price |
Pros, cons and our verdict
Rithmm is best for US sports bettors — especially prop players — who want a powerful mobile app and custom models. The main gaps are no soccer and premium pricing that climbs.
| Pros | Cons |
|---|---|
| Custom model builder | No soccer coverage |
| Deep player props | Premium tiers get pricey |
| Polished iOS/Android app | US sports only |
