Nutrition

Log meals against a real food database.

Search any food in the USDA database and get its full macro and micronutrient breakdown, or quick-add a meal by entering the calories and macros yourself.

NutritionLedger tracks your daily and weekly nutrition, and shows you how your intake compares to your goals. You can also create a meal plan and generate a shopping list for the week.

Exercise

Follow a plan, or build your own.

NutritionLedger tracks your workouts and shows your progress over time. You can follow a pre-built plan, or create your own custom plan with exercises, sets, reps, and weights.

Fasting

Start, pause, and track a fast properly.

NutritionLedger tracks your fasting consistency and average hours over time, keeps a full history of completed, incomplete, and cancelled fasts, and warns you before advancing a fasting stage.

The rest of daily tracking

The smaller entries that round out the full picture.

Not every part of your health needs a dedicated screen — some just need a quick, honest entry.

Water

Log intake in milliliters or liters, track today's total against your goal, undo a mistaken entry, and see 30 or 90-day history. A reminder appears if you're falling behind.

Measurements

Log weight, waist, hip, and height, with 30/90-day and all-time trend charts. Total weight change and entry count are calculated for you, in metric or imperial.

Daily Check-In

Log your energy and mood on a 1-10 scale with an optional note, and see your recent logs and monthly history feed into an overall wellness score.

Supplements & Allergies

Track Supplements, allergies, intolerances, and deficiencies. Entries can be marked inactive without losing their history, and export into your health PDF.

Analytics & Insights

One dashboard, built from everything you log.

Fifteen micronutrient cards track calcium, iron, magnesium, phosphorus, potassium, zinc, manganese, and selenium, plus vitamins A, C, D, E, K, B12, and folate — each with its own trend chart and food sources, against targets you can customize yourself.

Charts adapt from daily to weekly to bi-weekly as you switch between Today, 7D, 30D, 90D, or a custom range

Glycemic & Insulin HeuristicWarnings

Cross-Domain Correlations

How your protein intake connects to your workouts, or fasting to your energy.

Mobile Companion Agent

Log almost anything by sending a message.

NutritionLedger connects to Telegram, so you can log meals, workouts, and check-ins, ask questions about your fasting status or shopping list, and even mark your shopping list as complete — all by message.

NutritionLedger only listens on your own device — nothing is sent to a third-party AI
