The ideas behind Lumi
Lumidey is not a medical app. It was designed with inspiration from psychology research, to make everyday life a little calmer. Each of the principles below is tied to something we actually do in the app, and the studies that inspired us are listed at the end of the page.
Lumidey is not a medical device or a treatment. Reaching out to a professional when things feel hard is always a good idea.
1Small steps are enough
Habits settle through repetition, not big leaps. In one study, it took anywhere from weeks to months for a behavior to become automatic, depending on the person. Specific little plans like “when and where” also help people reach goals. That's why Lumidey suggests a single small step.
2Missing a day is not a penalty
There is no streak loss and no “you didn't do it today” warning. You simply continue where you left off. In the research, a single missed opportunity did not materially affect habit formation, and being kind to yourself after a slip often supported trying again rather than giving up.
3Calm focus, with short breaks
Brief breaks can help sustain attention. That's why focus sessions are short and breaks are part of the plan. (The study used a laboratory task and does not validate any particular timing rule.)
4Put your feelings into words
You can choose how your day feels and, if you want, what affected it (sleep, work, school, loved ones, body, weather, nature, loneliness) and add a note. All optional, and you can change it any time. Naming a feeling is an idea that has drawn interest in research on coping with emotions.
5You're in control
Steps you choose and take at your own pace tend to support more lasting motivation. That's why there is no pressure, no badge race and no ads. Plus does not speed up your progress.
6A calm world
Calm, nature-themed imagery can help rest attention. Lumi's world tries to carry that calm. (The studies used real nature and photographs. They are not direct evidence for an illustrated world, only design inspiration.)
7Your data stays on your device
No account. Your mood and notes are stored only on this device and are not sent anywhere. Many mental-wellbeing apps collect and share personal data. We chose not to. See our privacy policy for details.
