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.

- 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.
Feature-by-Feature Comparison
An honest side-by-side look at both tools. Green checks are not always better -- it depends on what matters to you.
Oxal AI pricing as of 2026: $12.99/mo or $99/yr. OxalateGuard: $4.99/mo or $39.99/yr. Both built by kidney stone survivors. We respect the work behind Oxal AI.
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.
