Trace Elements

Low-nickel & cobalt food diary

Free · In‑App Purchases

Private, offline food diary for low-nickel and low-cobalt diets. Log meals, see your daily total at a glance, scan barcodes and menus. No account, no ads. Trace Elements is a private, offline food diary for people on a restricted diet — a low-nickel diet for Systemic Nickel Allergy Syndrome (SNAS) or nickel-sensitive dermatitis, or a low-cobalt diet. Log what you eat and the app estimates how much nickel (or cobalt) each meal and each day adds up to, against a daily limit you set. It works fully offline, has no account, no ads, and no tracking. Your data stays on your iPhone. FAST DAILY LOGGING • Add foods to Breakfast, Lunch, Dinner, and Snacks • Enter amounts in grams or common serving sizes • A progress ring shows your running daily total at a glance • Copy a meal forward from yesterday with one tap • Save favorite meals and re-add them in seconds A FOOD DATABASE THAT GROWS WITH YOU • Hundreds of foods with reference values from the Rebelytics low-nickel and low-cobalt diet datasets • Edit or add your own values — they're saved and reused • Scan a packaged product's barcode to pull in its ingredient list • Can't find a food? Look it up in the USDA FoodData Central database, or use the in-app web lookup. These optional lookups are the only times the app goes online. RECIPES • Build compound foods (a sandwich, a stew, a takeout order) from ingredients and the app totals them automatically • Save them as reusable recipes SEE YOUR TRENDS • A calendar colors each day Good, Caution, or Over against thresholds you choose • Keep a per-day journal with mood and notes PRIVATE BY DESIGN • No sign-in, no user accounts • No advertising, analytics, or crash-reporting SDKs • Camera images from barcode and menu scans are read on the device and never stored or uploaded TRACE ELEMENTS PRO (optional subscription) • Track cobalt alongside nickel, with its own daily limit and dataset • Scan a restaurant menu: photograph it, pick your dish, and its ingredients are looked up — on supported iPhones, your phone's own on-device AI can estimate ingredients and portions without anything leaving the device • Export PDF reports to share with your clinician • Back up and restore everything: to a file, or to your own iCloud • $1.99 per month or $12.99 per year.

Managing it day to day was harder than it needed to be, and this was the only way I knew how to help. If it makes your days a little easier too, it's done its job. Please note: Trace Elements is a self-tracking aid. Reference values are estimates and vary by source, growing region, and preparation. It is not a medical device and does not provide medical or dietary advice. Always consult a qualified healthcare professional about your diet and any food sensitivities.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Scanned ingredients match by what they are: "sugar" is sugar, "oats" are oats; anything uncertain is left for you to confirm, never guessed. • Online lookups show every reading with its source sentence and only accept figures about the food you asked for. • "Look up all missing" proposes values beside the closest foods already in your list — nothing is applied until you choose. • Substitutes list related foods first. Saved recipes ask for servings.
