Iron Tracker is the simplest way to hit your daily iron goal and rebuild your levels. Low iron is the most common nutrient deficiency in the world, and it quietly drains you—showing up as fatigue, brain fog, cold hands, and feeling worn out no matter how much you sleep. The fix starts with knowing what you eat. Iron Tracker makes that easy. It's built for anyone who needs to stay on top of iron—people managing anemia, vegans and vegetarians relying on non-heme iron, and women boosting their levels before and during pregnancy. - Set your daily iron target based on your gender, age, and pregnancy status, using NIH guidelines - Log foods fast from a database of 225 high-iron foods - See heme vs non-heme iron, so you know what your body absorbs best - Log meals from a photo, barcode, or your voice with AI, then review every result before saving - Watch your daily intake at a glance with a clean progress ring - Track your streak on the weekly calendar - Earn XP, level up, and unlock 46 achievements for hitting your iron goal - Take on daily, weekly, and monthly challenges that push you to vary your iron sources - Everything runs on your device—no accounts, no data collection, no ads. That's it. A minute to set up, and you'll finally know exactly where your iron stands—every single day. Questions or ideas? Hit the contact link in Settings and I'll get back to you fast.
