About this app
Your daily energy and mood in one clear 0-100 score. Finally, explained.
Nadir is a dashboard for your energy and mood. Every day, you log how you feel in 30 seconds (energy, mood, sleep, stress) and you get a score calculated every morning. You finally spot the days when everything flows and the ones that feel heavier.
Your personal model refines itself based on your check-ins to estimate how you'll feel in the days ahead. Like a sleep app that learns from your nights, but for your overall energy.
Not just another mood diary or tracker that only logs the past. Not a vague horoscope. A real tracking tool to read your days, understand your cycles, and plan your week.
THE 3 ESSENTIALS
- Energy score 0 to 100, calculated every morning from a transparent formula. You see exactly why your score goes up or down.
- 30-second check-in: energy, mood, sleep, stress. Your data stays private and feeds your personal model.
- 7-day forecast: visualize your peaks and dips to plan what matters this week.
CONNECT YOUR WATCH (optional)
Apple Watch, Galaxy Watch, Fitbit, Oura, Whoop, Garmin: Nadir reads your sleep and heart rate variability via Apple Health or Health Connect. Your check-in fills in automatically every morning. You stay in control: edit values manually and turn it off anytime. Your data is never sold or shared.
WHAT MAKES US DIFFERENT
- A model that learns from you: the more you check in, the sharper your energy forecast gets. No black box, no magic promise.
- The "Why?" badge: every change is explained by a precise driver. You see what lifts or weighs down your day.
- The engine behind the "why": to explain your ups and downs, Nadir draws on a modern astrological reading of your birth chart and current transits. You explore that "why" at your own pace, or ignore it completely.
- Compare with friends (synastry): see how your cycles line up with the people close to you across 4 axes (Communication, Emotions, Energy, Values).
- No ads. Your data is encrypted, backed up, and hosted in Europe.

Updated on
Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
What’s new
Energy waves now cover your close ones: their upcoming dips and lifts, with the transit behind each one. You can also add a note under any close one ("Musician", "Former co-worker") and find them again from the search box. Editing a nickname or a note no longer sends you back through the birth data. And if a close one's birth time came from the old 12:00 default, the app now asks you to confirm it instead of treating it as given.
