Two Builders, Different Approaches

OxalateGuard vs Oxal AI

Both apps were born from the same frustration: kidney stones and a healthcare system that leaves patients to figure out oxalate on their own. Here's an honest look at how they differ.

Built from the Same Frustration

Oxal AI and OxalateGuard share something rare: both were built by kidney stone survivors who got tired of inadequate tools and decided to build their own. That shared experience matters. It means both apps understand what stone formers actually need, even if they solve the problem differently.

Oxal AI leans into protocols and automation: set it up, follow the guidance, let the AI handle the details. OxalateGuard leans into comprehensive data and hands-on tools: scan, search, analyze, and make informed decisions yourself. Neither approach is wrong. The right choice depends on how you prefer to manage your health.

What Oxal AI Does Well

Credit where it's due. Oxal AI has genuine strengths that are worth acknowledging.

Protocol-First Design

Rather than asking you to track every food manually, Oxal AI focuses on structured prevention protocols: hydration targets, sodium budgets, and calcium-oxalate meal pairing.

Heat Day Auto-Adjustment

Weather-aware hydration targets that automatically increase when temperatures rise. A genuinely clever feature that no other kidney stone app offers.

Doctor Export Reports

Generate progress reports to share with your urologist. Structured data your doctor can actually use during visits.

Minimal Input Required

Designed to reduce tracking friction. Less manual logging means lower barrier to staying consistent over time.

Clean, Focused UX

Does fewer things but does them with a polished, focused interface. No feature bloat, just the protocol essentials.

AUA Guideline-Based

Recommendations aligned with American Urological Association guidelines for kidney stone prevention.

Different Approaches to the Same Problem

Oxal AI asks “What protocols should you follow?” OxalateGuard asks “What is in your food?” Both questions matter.

Oxal AI: The Protocol Guide

  • AI-driven prevention protocols
  • Hydration targets (2.5L urine output)
  • Sodium budget under 2,300mg
  • Calcium-oxalate meal pairing guidance
  • Heat day weather alerts
  • Minimal manual input

Best for: People who want to be guided through prevention step-by-step.

OxalateGuard: The Data Toolkit

  • 2,549 foods from 15+ peer-reviewed sources
  • Barcode scanning (200K+ products)
  • Restaurant menu photo analysis
  • Recipe URL converter with swap suggestions
  • 50+ chain restaurant guides
  • Community contributions and recipes

Best for: People who want to explore, research, and make informed decisions with deep data.

Where OxalateGuard Goes Further

Protocol guidance is valuable, but it doesn't help you figure out what's in the soup you just ordered. Here's what deeper data and more tools unlock.

Less Than Half the Price

OxalateGuard Premium is $39.99/year. Oxal AI is $99/year. And OxalateGuard's free tier already includes the full food database, daily tracking, barcode scanning, and restaurant guides. No credit card required to start.

2,549 Foods, 15+ Sources

Every food shows exactly where its data comes from. When studies disagree, our consensus algorithm identifies statistical outliers and computes reliable values. Oxal AI's food database size and sources are not publicly disclosed.

Scan, Snap, Convert

Barcode scanning for packaged foods, photo analysis for restaurant menus, and recipe URL conversion with swap suggestions. Three ways to get oxalate data that protocol-based apps do not provide.

50+ Restaurant Guides

Pre-analyzed menus from chain restaurants with risk-coded dishes, ingredient breakdowns, and questions to ask your server. Real guidance for dining out, the hardest scenario for stone formers.

Works on Every Device

Oxal AI is iOS-only. OxalateGuard works on iPhone, Android, iPad, and desktop. Add it to your home screen for an app-like experience. No app store required.

Beyond Kidney Stones

CKD, IBD, bariatric surgery, interstitial cystitis, vulvodynia -- oxalate matters for more than just kidney stones. OxalateGuard supports multiple conditions with tailored daily targets.

The Bottom Line

Oxal AI is a solid choice if you want an AI-guided prevention protocol with features like hydration tracking and heat day alerts. OxalateGuard is the better fit if you want deep oxalate data, barcode scanning, restaurant menu analysis, and recipe conversion at less than half the price, on any device.

Both apps come from a real place. Both founders know what it feels like to pass a stone. The best choice is whichever one you will actually use consistently.
