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.

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.
