Smart Categorization

Categorized before you open the app

Thermal categorizes transactions on import, then learns from your corrections. Create rules once and never recategorize the same merchant again.

Automatic categorization

Transactions are categorized the moment they sync. Thermal maps merchant data to a clean taxonomy so you see groceries, not MCC code 5411.

Custom category rules

Create rules by merchant name, exact match, or prefix. Once set, every future transaction from that merchant is categorized automatically. No more re-categorizing the same coffee shop every week.

Bulk reassignment

Recategorize months of transactions in one action. Change all Uber transactions from Transportation to Business and Thermal creates a rule to handle future ones too.

Visual Breakdown

Your spending as a treemap

Categories sized by spend. See at a glance what takes the biggest share of your income. Drill into any category to see individual transactions.

Budget Tracking

Budgets that keep up with your spending

Real-time budget progress, automatic recurring detection, and category-level limits. No manual entry required.

Category budgets

Set monthly spending limits by category. See real-time progress as transactions flow in. Know you've hit 80% of your dining budget before the month is over.

Reactive spending totals

Budget spending recomputes instantly when transactions change. Recategorize something and your budget progress updates in real time across every view.

Recurring detection

Thermal automatically identifies recurring charges -- subscriptions, utilities, memberships -- so you know your fixed costs without manual entry.
