Store description excerpt

Are you eating enough to support your training? 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. No streaks, no guilt, no deficit scoreboard. Idunia's focus is adequacy: noticing where there is room to add, because for athletes, eating enough is what supports training, recovery, and health. LOG FOOD THE EASY WAY Type a meal in plain words, or snap a photo with Pro. With your permission, Idunia's AI reads it and drafts the entry; every gram stays editable, and manual logging always works without AI. SEE THE NUTRITION THAT MATTERS TO ATHLETES Beyond calories and macros, Idunia tracks iron and 30+ nutrients that matter for female athletes, with special care for iron: your iron picture accounts for your cycle, because menstrual iron loss is real and rarely accounted for. TRAINING IN, FUELING OUT Connect Apple Health and your workouts import when you open the app; a Sync now button 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 An optional cycle layer keeps period logging on your device (never on our servers) and uses it as context, like iron needs around menstruation. No predictions, no fertility features. HONEST NUMBERS, SOURCED The numbers Idunia computes come with plain-language sources. Tap "Sources" on the fuel card, or "Sources and references" in Settings, and read where the numbers come from, with links to the primary literature. The same material is offered during your first-run setup. A GENTLER MODE WHEN YOU WANT IT Gentle mode softens the display for days or seasons when numbers are not what you need. The support resources stay one tap away in either mode. Logging and your last 7 days are free. Idunia Pro unlocks your full history, trends, and photo logging: $99 per year (USD, US storefront) with a 7-day free trial on the annual plan for new subscribers, or $15 per month (no trial). Subscriptions auto-renew until canceled in your App Store settings. Idunia is not medical advice. It is an educational tool for healthy adult athletes; talk with a clinician or registered dietitian about your individual needs. AI estimates are estimates, and everything stays editable.
