Personal finance for real life
Simple budgets. Numbers you can trust.
Watchtower helps you understand your money each month: balances, spending, and what remains in your budget, with a quiet watch for charges and changes you might have missed.
Less clutter. Edits that stick. Secure by design. No shame language.

Why Watchtower
Know where your money stands this month.
See what’s in your accounts, where money went, and what remains in your budget, without drowning in charts or fighting edits that don’t stick.
Budgets that stay simple
Set category amounts for the month. See budgeted, spent, and remaining in plain language.
Transactions you control
Recategorize once and it sticks. Original bank statement text stays visible and recoverable.
Alerts worth a look
When a charge looks unfamiliar or a subscription jumps, Watchtower can surface it quietly, not as a feed of noise.

How it works
From connected accounts to a clear month.
Step 1
Connect accounts securely
Link banks through a trusted provider. Watchtower is designed so we never need your bank password.
Step 2
See the month at a glance
Balances, recent transactions, and budgeted / spent / remaining land on a simple Overview, not a chart maze.
Step 3
Categorize and set budgets
Assign categories that stick through re-sync. Set calendar-month budgets for the categories that matter.
Step 4
Catch what you might have missed
Optional, calm alerts for unfamiliar merchants, rising recurring charges, and other patterns worth a second look.
Built with care
Secure, private, and calm on purpose.
Household money data is sensitive. Watchtower favors minimization, clear data layers, and language that never guilts you.
We prefer: “Remaining this month,” “Uncategorized (12),” “Set a budget for this category,” and “This charge may be worth checking.”
We avoid: shame copy about budgets, engagement theater, and “AI-powered revolution” hype.
