About this app

Idunia answers one question most nutrition apps ignore: are you eating ENOUGH to support your training?

Eat, train, and track with intent. Idunia leads with adequacy, not restriction. It
is a maintenance-and-sufficiency tool, not a weight-loss app. No aggressive deficits. No "good food" or "bad food." Every nudge points toward eating enough to recover and perform your best.

WHAT IDUNIA DOES

• Log food in plain language. Type or speak what you ate, like "oatmeal,
banana, two eggs," and Idunia turns it into a full nutrition breakdown. Edit
anything by hand.
• See your fueling status. Idunia estimates your energy availability, whether
your intake is keeping up with your training load, and surfaces it as a clear
daily stat line.
• Track 30+ micronutrients, with a focus on the ones that matter most for
female athletes, including iron.
• Log training. Your sessions feed your energy and fueling picture.
• Cycle as context, done right. Optional, opt-in cycle tracking adds context
and iron-timing facts. No shaky 4-phase meal prescriptions. Just defensible
information, kept private.

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 anytime. 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, take medication, or have a nutrition, eating, or body-image related condition, talk to a sports dietitian or physician.

MEMBERSHIP

Idunia is a subscription. Start with a free trial, then choose monthly or annual. Manage or cancel anytime in Google Play.

What’s new

Iron is now graded against the flow you logged, so a heavy day asks for more. Vitamin D and vitamin C targets are corrected. Notifications are calmer and no longer tied to your cycle. When two apps send the same run, one copy counts. Today shows what set your fuel target. The Trends header describes the range you picked. A meal can carry a label, like Breakfast or Lunch. Sync messages say what happened to your workouts. You can search your saved meals.
