Rithmm is a polished iOS-first AI prediction app that charges $29.99 to $99.99 per month for picks across the NFL, NBA, MLB, college basketball and golf — but unlike PropsBot.AI, it does not publish a third-party audited track record at scale, so bettors are largely trusting its "4M+ winning predictions" marketing claim on faith.
What Is Rithmm?
Rithmm is a sports-betting prediction platform built primarily as an iOS and Android app, with a companion web experience. Its homepage tagline is “Know what to pick. In seconds” and it positions itself as “Smart Sports Predictions. Backed by AI. Built for Speed.” The product surfaces three core outputs: AI-generated game picks, AI player props, and “Bolt” picks — high-confidence bets flagged by the model. A no-code model builder lets paying users tune their own prediction weights, and a line-comparison tool checks odds across sportsbooks.
The company cites credentials including MIT alumni, former athletes, data scientists and vetting by Billy Walters’ quant team. Headline claims include “4M+ winning predictions” and “1B+ data points crunched.” Sports covered: NFL, NBA, WNBA, MLB, NCAAB and golf. No published NHL coverage as of this review.

How Rithmm’s Model Works
Rithmm describes its system as a stack of machine-learning models trained on what the company calls “1B+ data points.” The user-visible layer is straightforward: every game and player prop gets a model price, a recommended side, and a confidence tag. “Bolt” picks are flagged when the model believes its edge over the sportsbook is historically large. The Premium tier unlocks a no-code model builder where users can re-weight factors like rest, pace, opponent strength and recent form, and an NFL+NBA “Player Adjustment” tool that lets the user override projections for specific players.
What Rithmm does not publish — at least anywhere we could find at audit time — is a third-party-verified bet-by-bet results log, calibration curve, or closing-line-value report. The headline “4M+ winning predictions” figure is an aggregate marketing claim, not a graded P&L. That’s the single biggest gap for a sharp bettor comparing tools. Our performance methodology page explains why graded ROI and Brier score matter more than raw “winning predictions” counts.
What Rithmm Does Well
- Mobile-first UX. If you live in an app, Rithmm’s interface is fast, clean and built for thumb-scrolling between games. Bolt picks surface quickly and the line comparison tool is a useful sportsbook-shopping shortcut.
- Content marketing moat. Rithmm has invested heavily in a sprawling glossary and daily-pick content network — roughly 218 indexed URLs covering terms from “RBI” to “moneyline.” That’s genuinely impressive SEO work and a real strength for casual bettors who want to learn while they bet.
- Model builder for tinkerers. The no-code custom model is rare in this category. If you enjoy tweaking weights and seeing how rest, pace or recent form changes a projection, you will get value out of Premium.
- Broad WNBA & NCAAB coverage. Rithmm covers WNBA and college basketball, both of which PropsBot does not currently model.
Where PropsBot Has the Edge
- No app install, works in any browser. PropsBot loads on iOS Safari, Android Chrome, a work laptop, or a tablet — same picks, same UI, no App Store gate, no version-update lag. Cancel takes one click on the web, not three taps through Apple’s subscription manager.
- Free daily picks, in public. Our free NBA picks, free MLB picks and free NFL picks ship every game day on the public blog. Rithmm’s equivalent picks live behind the subscription wall.
- Audited track record at scale. 218,000+ graded picks are public on our track record page, with audited unit ROI of +25.1% on NBA and +31.7% on MLB. Rithmm publishes “winning predictions” aggregates rather than graded P&L.
- Calibration that beats Vegas. Our MLB model posts a Brier score of 0.1903 vs the Vegas closing line at 0.1947 — lower is better, and the gap is the entire point of having a model. Rithmm does not publish a Brier score we can compare against.
Pricing Comparison
Rithmm charges $29.99/month or $19.99/month annual on the Core tier, and $99.99/month or $83.33/month annual on Premium. Premium adds advanced statistics, the deeper model builder, and the NFL+NBA Player Adjustment tool. A 7-day free trial is offered in-app, subject to App Store rules.
PropsBot.AI is $34.99/month flat, with no upsell to a “Premium” tier — every subscriber gets the full model. A free tier publishes daily picks publicly with no credit card required, so you can grade the model yourself before paying. Annual pricing is available on the pricing page.
Net: Rithmm’s annual rate is cheaper if you commit, but you pay up-front for a model without a graded audit. PropsBot’s $34.99 monthly is no-commitment and the ROI is verifiable before you pay.
Who Should Choose Each Tool?
Choose Rithmm if you are a mobile-native bettor who wants a polished app, you bet WNBA or college basketball regularly, you enjoy tweaking your own model weights, and you are comfortable taking AI-prediction performance on a marketing claim rather than an audited log.
Choose PropsBot.AI if you want a browser-first tool that opens anywhere, you want to grade the model yourself against 218,000+ public picks before paying, you bet NHL or PGA props (not covered by Rithmm), and you value Brier-score-calibrated probabilities over “Bolt” confidence tags. See our best AI for NBA props and best AI player prop tools 2026 roundups for how we stack against the wider category, including our PropGPT alternative page. If you came here for the glossary angle, our RBI in baseball entry is a fair head-to-head against Rithmm’s widely-ranked RBI post.
PropsBot publishes a fully transparent Confidence Score on every pick — Rithmm does not. Our score is a calibrated 0–100 model output, the same number that drives our public 218,000+ graded pick log (+25.1% NBA ROI, +31.7% MLB ROI). The model’s calibration is verifiable: Brier 0.1903 on MLB, better than the Vegas closing-line Brier of 0.1947 across the same window. The full math is documented at /performance-methodology/. Rithmm’s “Bolt” tag is an opaque high-confidence flag without published calibration, no per-score hit-rate table, and no Brier score we can compare against. The transparency is the differentiator.
FAQ
Is Rithmm worth $29.99 per month?
If you bet daily across multiple sports and want a mobile-first app with a custom model builder, the Core tier can pay for itself on a handful of correctly-sized bets. The catch is that Rithmm does not publish a third-party-audited unit-ROI log, so you are taking the model’s edge largely on faith. PropsBot.AI’s $34.99/month plan is comparable in price and publishes a 218,000+ graded-pick audit.
Does Rithmm have a free trial?
Yes — Rithmm offers a 7-day free trial inside the iOS and Android app. The trial unlocks Core-tier picks and is subject to App Store and Google Play subscription rules. To compare, PropsBot publishes free picks daily on the public blog with no signup required.
What sports does Rithmm cover?
Rithmm covers the NFL, NBA, WNBA, MLB, college basketball and golf. It does not currently cover the NHL. PropsBot covers NBA, NFL, MLB, NHL and PGA, so NHL bettors will get more from PropsBot and WNBA/NCAAB bettors will get more from Rithmm.
How accurate is Rithmm’s AI?
Rithmm advertises “4M+ winning predictions” and “1B+ data points,” but these are aggregate marketing figures rather than a graded P&L or calibration metric. PropsBot publishes graded unit ROI (+25.1% NBA, +31.7% MLB) and a Brier score of 0.1903 on MLB — a calibration metric directly comparable to Vegas’s 0.1947 closing-line Brier. See our methodology page for how these are computed.
Is Rithmm a paid app or free?
The Rithmm app is free to download with a 7-day free trial, after which Core ($29.99/mo) or Premium ($99.99/mo) is required to view picks. PropsBot.AI is browser-based with a permanent free daily-picks tier and a $34.99/month plan for the full model.
Rithmm vs PropsBot — which is better for player props?
Both tools ship AI player props. PropsBot publishes audited per-sport ROI and a Brier score for prop calibration; Rithmm publishes aggregate “winning predictions” counts. If you are evaluating player-prop tools and want a verifiable edge metric, see our best AI player prop tools 2026 roundup.
Can I cancel Rithmm easily?
Rithmm subscriptions are managed through the App Store or Google Play, so cancellation runs through Apple or Google’s subscription manager. PropsBot subscriptions cancel in one click on the web, with no platform gatekeeper.
