What you did on Tuesday explains how you feel on Thursday.
Wellcast is a one-minute daily check-in that finds the patterns in your mood, sleep, energy and symptoms. Including the ones that show up days later, after you've already forgotten the cause.
Open beta on iPhone, free while in beta. Android is next.
Nobody notices this on their own.
By the time the effect arrives, the cause has left your memory. Wellcast keeps the record so the connection can be found.
-
Check in once a day
Mood, symptoms, habits, sleep, energy and a journal line if you want one. It takes less than a minute.
-
Wellcast compares your days
It looks at days when something happened against days when it didn't, on the same day and up to five days after.
-
You get Ecos
Plain-language findings about what affects you, how much, and how many days later. Your first one usually appears after about a week.
Findings you can trust, or none at all.
Ecos run real statistics on your own data: a Welch's t-test for whether an effect is there, and Cohen's d for how big it is. Every Eco shows its size and how confident Wellcast is.
In the first week only strong effects show up, marked as early signals. With more check-ins they either hold up or disappear. When there isn't enough data, the app says so instead of guessing.
- Example Ecos
- Alcohol Mood dips 2 days later High confidence, 28 days
- Morning walk Energy improves Same day Moderate confidence, 19 days
- Late coffee Sleep quality drops Next day High confidence, 24 days
- Headache Energy drops Next day Early signal, 9 days
One app instead of five.
Ecos get better the more of your life they can see, so everything lives in one place.

Your data stays yours.
Wellcast is paid for by the people who use it, not by selling what they share. Health data is the most personal data there is, so the business model was chosen to never need it.
- No ads, and no ad networks.
- No third-party analytics SDKs in the app.
- Encrypted in transit and at rest.
- Delete your account and every entry from settings.
- Written for Brazil's LGPD and the EU's GDPR.
A small company with one job.
Wellcast is built full-time by its founder, Amanda Gama, in Brazil.
Wellbeing apps are good at collecting data and bad at telling you what it means. People log for weeks, look at a chart and stop. Wellcast is built on the opposite bet: a few honest findings about your own body are worth more than any dashboard.
The delayed effects are the core of it. Same-day patterns you can often spot yourself. The ones that take two days are where people need help, and where Wellcast does something a person can't.
