Are you eating enough to support your running? Idunia is built for women who run, and that is the question it answers every day.

Most nutrition apps ask how little you can eat. Idunia looks at the food you log and the training you do, and shows whether your fueling is keeping up, with a gauge that reads like a gas meter: Running low, Building, or Fueled up. Idunia leads with adequacy: noticing where there is room to add, because for runners and other endurance athletes, eating enough is what supports training, recovery, and health. Whether you are building toward a half marathon, a marathon, or your next long run, every nudge points toward eating enough.

LOG FOOD THE EASY WAY
Type or speak what you ate, like "oatmeal, banana, two eggs," or scan a barcode. With your permission, Idunia's AI reads a typed or spoken meal and drafts the entry; every gram stays editable, and manual logging always works without AI. With Idunia Pro, you can also log a meal from a photo.

THE NUTRITION THAT MATTERS TO RUNNERS
Beyond protein, carbs, and fat, Idunia tracks your iron intake and 30+ nutrients that matter for female athletes. Your iron picture accounts for your cycle, because menstrual iron loss is real and rarely accounted for.

TRAINING IN, FUELING OUT
Log a run by hand, or connect Health Connect and Idunia reads the workouts your watch or running app saves there. It checks for new workouts on its own, and Sync now in Settings pulls the latest anytime. Training energy feeds your fueling picture, so a long run raises what "enough" means that day.

YOUR CYCLE AS CONTEXT
Optional cycle logging adds context to your fueling, like iron needs around your period.

HONEST NUMBERS, SOURCED
Tap "Sources" on the fuel card, or "Sources and references" in Settings, to read the published research behind the numbers Idunia computes, in plain language with links to the primary literature.

A GENTLER MODE WHEN YOU WANT IT
Gentle mode softens the display for days or seasons when numbers are not what you need. Support resources stay one tap away in either mode.

PRIVATE BY DESIGN
Idunia is built so your health data stays yours. No advertising or analytics trackers ever touch your nutrition, training, weight, or cycle data. Cycle data is stored encrypted on your device. You can export or delete your data at any time. Adults 18+, US only.

NOT MEDICAL ADVICE
Idunia is an educational wellness and performance tool. It does not diagnose, screen, or treat any condition, and its estimates are based on the information you enter, not a medical exam. If you are pregnant or breastfeeding, or have a medical, eating, or body-image related condition, talk to a sports dietitian or physician.

FREE AND PRO
Logging is free, along with your daily fueling gauge, cycle logging, gentle mode, and your last 7 days of history and trends. Idunia Pro adds photo logging, meal history before those 7 days, and 30-day and 90-day trends. Pro is $99 per year with a 7-day free trial on the annual plan, or $15 per month with no trial (USD). Subscriptions auto-renew until canceled; manage or cancel anytime in Google Play. If Pro ends, you keep the free tier.
