Tool Comparison

Fenrir Ledger vs. Notion Credit Card Tracker

Many churners build DIY Notion databases to track cards. We compare a purpose-built tracker to the most popular spreadsheet alternative.

Our Verdict

For any churner tracking more than two cards, Fenrir Ledger saves more time than a Notion template costs to build. Automatic deadline alerts alone are worth the switch — a missed bonus deadline wipes out months of spend.

FAQ

Is Fenrir Ledger free?

Yes. The Thrall tier is free and supports up to 3 cards with full deadline tracking. The Karl tier ($3.99/mo) removes the card limit and adds household sync.

Can I keep using Notion alongside Fenrir Ledger?

Absolutely. Many users migrate deadline-critical fields to Fenrir Ledger while keeping other financial notes in Notion. You don't have to choose one tool for everything.

Does Fenrir Ledger connect to Notion directly?

Not natively — Notion's API doesn't expose a standard card-tracker schema. The fastest path is to export from Notion as CSV and import into Fenrir Ledger via the CSV importer.

What if my Notion template has custom fields Fenrir Ledger doesn't support?

Fenrir Ledger tracks the fields that matter most for churning: annual fee date, bonus deadline, spend requirement, statement credits, and notes. Custom fields outside this scope can stay in Notion or a notes app.
