How it works
Three moves, one tap.
II
Read the days ahead
MomentumX scores every free hour in the next seven days — thirty on Premium — and ranks the ones that suit that kind of work.
III
Book the winner
Accept a slot and it is written into a separate “MomentumX” calendar. Your own calendars are never modified.
Why timing matters
Not all days are created equal.
Some days are made for bold action — launching a project, having a difficult conversation, closing a deal. Others call for rest, reflection or patience. MomentumX decodes these natural rhythms so you are never guessing.
Act
The hours when your energy, focus and outside conditions line up in your favour.
Wait
The stretches better spent recovering than spent pushing against yourself.
Inside the app
Three screens, one question: when?
Everything is inspectable. No score arrives without the reasoning behind it.
Find your hour
Today’s peak window, what is happening right now, and the right time for the event you picked.
Plan
Seven days of events and free windows side by side. “Plan my week” fills them in one pass.
Insights
Your hourly energy curve for the day, split by focus and connection, plus what your model has learned.
Life area guidance
Four parts of life, four different clocks.
The hour that suits a pitch is not the hour that suits a hard conversation. MomentumX weighs the factors differently depending on what you are placing.
Business & career
Pitches, negotiations, deep work and the decisions you do not want to make while depleted.
Relationships & romance
Difficult conversations, reconnections and the moments that deserve your patience.
Health & wellness
Recovery, appointments and the quiet hours your body is actually asking for.
Sports & fitness
Training blocks placed where your physical cycle is rising instead of bottoming out.
The instrument
Six signals, all inspectable.
Every suggestion opens into the factors behind it, each with its own weight. A reason in plain language, not a black box.
Chronotype
Your personal peak window — from a questionnaire, or measured from Apple Health sleep data.
Biorhythms
Three cycles — physical, emotional, intellectual — derived from your date of birth.
Geomagnetic activity
The official NOAA planetary Kp index, pulled fresh for the days you are planning.
Weather & pressure
Local weather and the stability of pressure over the last hours, not just today’s headline.
Lunar phase
Precise astronomical calculation of the phase for your date and location.
Time of day
Circadian bonuses and penalties tuned to the kind of task you are placing.
Plan your week
Say what matters. Get a week back.
Deep work three times, one important conversation, two workouts. MomentumX allocates them into the best free hours of the next seven days. Review the plan, then add everything to your calendar at once.
Deep work ×3
Hard conversation ×1
Training ×2
Recovery ×1
Your model
It learns you, on your iPhone.
Rate each event 1–5 after it happens. MomentumX correlates every factor against your own ratings and shows which ones actually move your numbers — and which ones do nothing for you. The model is computed on device and never leaves it.
Key features
A planner, a nudge, and a reason for both.
Built-in planner
Reads your calendar, finds the free windows and writes accepted slots into a separate “MomentumX” calendar.
Smart reminders
A nudge an hour before a favourable window, and a question afterwards: how did it actually go?
Daily wisdom
Short, practical notes through the day — small nudges to think clearer and decide better.
Widgets & Siri
Today’s forecast on the Home Screen, focus sessions on the Lock Screen, “When is my peak?” in Siri.
