Strength and phases

What counts for strength?

Your strength (the optional view of what you build with people) doesn’t grow with the number of your contacts, but with real meetings and real contact.

What counts

• Swapping cards in person. Swap your cards when you meet (Hold Together). Then you’ve met.
• Staying in touch. If you meet again and confirm the meeting, or you reply to each other in your one-to-one chat on a few different days, you’re connected. Then that person counts fully. Someone you met only once counts only partly.
• People with a higher phase. Everyone shows a phase card on their card (their level in strength, from 1 to 9). Someone showing a higher one than your own phase counts up to double for you, someone one phase lower counts half. If someone shows no phase card, they count like someone at your level.

For reply days, only the days on which you replied to each other count, never what you write. They only count while strength is on.

Your circles

From your contact, the app forms your circles every four weeks: the closest (up to 10 people), the close one (up to 50) and the wide one (up to 150). You find them under Nodi › Strength › Your Circles. You can hold up to 5 people in your closest circle and quietly take anyone out. Only you see your circles.

If someone in your circles grows stronger (they show a higher phase card) and you stay in touch, they gradually count more for you: fully in the closest circle, half in the close one, a quarter in the wide one. When much of it adds up, Nodi shows “Tailwind” under Strength.

What doesn’t count

• What you write.
• Your address book and imported contacts.
• Communities and group chats.
• Connections made only by link or QR code, without meeting in person, count little.

What happens next

When your bar is full, the next phase begins, with a new card. See Phases and phase cards.

Note: The app calculates strength only on your device. Nothing goes to our servers for it. Exceptions: if you show a phase card on your profile, it goes out with your profile. And when you move up by inviting, our server notes that someone came through your link.
