What the in-game UI doesn't show you
Tomodachi Life: Living the Dream shows relationships moment-to-moment — a heart over a Mii's head when something good happens, a problem icon when something is brewing — but it doesn't keep a per-pair history you can scroll back through. Once your island has more than a dozen Miis, you start losing track of which couple was about to confess, which friendship cooled off after a bad gift, and who is currently in the awkward post-rejection phase.
The Relationship Tracker on this page is the smallest possible notebook for that gap. For each pair, you log who's involved, the current status (besties, crush, tense), the bond level, and one short note about what happened last. Nothing more. It's a memory aid, not a database — kept short on purpose so you actually maintain it.
What to log — and what to skip
The tracker becomes useless if you log every interaction. The trick is to only log the bonds where memory will fail you a week later.
- Pairs about to flip status. A friendship about to become a crush, a crush about to confess, a tense pair about to argue. These are the moments you most want to come back to.
- Pairs you're matchmaking deliberately. If you've placed two Miis next door specifically to push them together, log it. The tracker will remind you to follow up.
- Tense pairs you don't want to forget. Friendship damage in Living the Dream doesn't always recover automatically — the tracker reminds you to step in.
- Skip casual likes. Most Miis like most other Miis. Logging every "they get along" pair fills the tracker with noise.
Matchmaking workflow — Compatibility Tester → Relationship Tracker
The two tools work best as a pipeline. Use the Compatibility Tester on a candidate pair before you build them, then log the resulting pair in the Relationship Tracker once they're placed in-game. The Tester answers "will they click?"; the tracker answers "have they clicked yet, and what happened last?"
If the Compatibility Tester gives a high forecast, set the pair to status Crush from the start with a note like "high tester forecast, watch for confession." If the forecast is mid-range, start as Besties and let the tracker tell you whether the bond grows over the next few sessions. The full workflow is documented in the Matchmaking without chaos guide.

Frequently asked questions
Does the tracker pull data from my Switch?
No — there is no public API for Tomodachi Life save data. Every entry is something you observed in-game and typed in. This is what keeps the tracker private and offline-capable.
How many pairs can I track?
The tracker has no hard limit, but practical experience says 30-40 pairs is the maximum a player will keep maintained. Past that, the tracker gets cluttered. If you have a 100-Mii island, log only the relationships that genuinely matter to your save story.
What happens if I export the tracker and import it on another device?
The data transfers cleanly — IDs, statuses, notes, bond levels. This is the only way to move tracker data between browsers, since local storage doesn't sync across devices.
Why local storage instead of an account?
Privacy, speed, and zero friction. There's nothing to sign up for and the tracker works offline. The trade-off is you have to manage exports yourself if you want backups — but for a memory notebook tied to a single save file, local storage is usually exactly the right shape.
