What Davka does and does not do

What the app does

Logging

Supplements and vitamins by part of the day, a whole part of the day with one tap.

Supplements

A catalog of supplements, your own items with ingredients and brand, and a schedule for only some days of the week.

Water

A daily goal and quick logging.

Caffeine

Logging by drink and a caffeine curve, a rough estimate of the caffeine in your body based on the time and size of each entry.

Custom sections

Anything else you want to keep track of, such as habits.

Reminders

Local notifications for parts of the day; you can log supplements straight from them.

Widgets

Supplements, water and the caffeine curve on the Home Screen, and the caffeine estimate on the Lock Screen too.

Overviews

A calendar where you can fill in a missed day later, and Insights for a period you choose.

Export

A PDF report for a month, a quarter or a year, and a CSV with the full history.

With your permission, Davka writes nutrients, water and caffeine to the Health app.

What the app does not have

Advice

The app does not tell you what to take or how much, and it does not rate supplements. It is a record, not an advisor.

Medicines

It is made for supplements and vitamins, not for medicines.

Account

No registration and no sign-in.

Ads

No ads and no analytics.

Sharing

Records cannot be shared with other people directly from the app.

The price and more answers are in the FAQ.
