Not a chatbot. Not a tracker. A coach that reads what you log, reacts in context, and adjusts your plan as your life actually unfolds.

Sisu is built around a simple thesis: most people don't need another tracker or another app. They need someone, or something, helping them daily. Noticing the patterns. Suggesting the next move. Being honest when the data and the goal don't match.
That role used to be a personal trainer, a nutritionist, a sponsor, a thoughtful aunt. For most people it's unavailable or unaffordable. Sisu is the version that scales: coached on what good coaching actually looks like, free at the base, paid when you want more depth.
Most software is used occasionally: bank apps, travel sites, ride share. Wellness is different. Weight, sleep, mood, energy, hair, skin are daily realities. They reward consistency. They punish neglect. They are exactly the conditions a coach is useful for.
Sisu shows up every day. Not to nag, not to gamify, not to "build the habit" through artificial pressure. Just to read what you logged, notice what changed, and tell you what to do about it. That's the role. That's the entire pitch.
