A hundred
small shifts
can change
a life.

We build apps for positive behavioral change. A major shift on day one rarely works, but a small change over 100 days can work miracles. We'll help you do that.

100 Dots · 1 Habit
Mission

Build useful software that helps people become who they are trying to be.

Change isn't a singular grand event. It's the cumulative weight of tiny repetitions. Our apps are designed to facilitate the mundane, the routine, and the daily "again." We focus on reducing friction where it counts and adding it where it protects your focus.

100
Threshold
The Name

Centumis comes from centum — one hundred.

One hundred is the threshold of mastery. Not the mastery of an expert, but the mastery of a habit. We believe in modest moments and the power of repetitions. Centumis is about the journey to the hundredth repetition, where the change truly takes root.

Core Pillars

Four principles · One system
01

NOTICE

The right moment reveals itself quietly. We build our apps that respect your attention while creating awareness.

02

ACT

Each step is smaller than you think. Our apps are designed to do micro-actions. Do it daily and you're own your path to massive transformation.

03

FEEL

Progress must be felt, not just logged. Our feedback loops are visceral, encouraging, and immediate.

04

GROW

Every return makes the loop more personal. System adaptability is the core of long-term behavioral success.
