A budgeting app for people exhausted from budgeting apps

Know what you can spend, then get back to your life.

What Tend is

Tend is a calendar-based budgeting app for households that want to get on top of their finances without it consuming all their time.

Most apps over-complicate this with too many categories and chaotic dashboards, requiring you to manually assign every penny, organize merchants, and fix broken automation rules.

You think, "how is everyone doing with this? Is there anything better?"

Tend is different in three ways:

  1. A calendar is the engine for your budget.
  2. A short list of 12 curated categories is all you need.
  3. A single number shows how much you can spend each week.

This means less maintenance and more confidence to spend your money on things you value.

How calendar-based budgeting works

The whole system is built on this simple realization.

Some payments have due dates (and calendars love dates).

Two overlapping calendar day cards: Jan
  1 listing Tuition $500, Charity $250; Jan 2 listing Paycheck $5,400, Rent $2,100,
  Netflix $17
  • Your rent is due the 1st
  • Your paycheck lands the 15th
  • Your subscription renews each year

When you add all your financial commitments to the calendar, your lifestyle becomes visible. What's left after these are accounted for is the money you have control over.

Most budgeting systems treat all spending as equally up for debate every month. Calendar-based budgeting recognizes that a large portion of your money is already spoken for, and stops asking you to manually allocate money for every commitment, every period.

The calendar does the work for you.

Why most budgeting apps feel like a second job

YNAB, Monarch, EveryDollar, GoodBudget. Each of these apps gives you a blank slate to manage your own categories and fund them all at the start of each month. This is called zero-based budgeting.

But after you've made 100 categories and still can't decide if paying the babysitter is "Kid Stuff" or "Date Night", you start to wonder if more might not be the answer.

However, zero-based budgeting did get something right — the security of knowing your expenses are all funded ahead of time.

Tend kept that and improved it by removing the category confusion and letting the calendar do the tedious work for you.

Who built Tend

James Kerr built Tend after 17 years of tracking his own spending.

What started with a simple spreadsheet in college evolved into developing custom plugins for his YNAB budget. After marriage and the arrival of their second child, he needed an alternative to the time-consuming apps he'd used in the past.

Tend became that alternative:

  • a short list of curated categories
  • fixed expenses scheduled,
  • and a single weekly spending target for variable expenses.

James founded Tend in 2024 and runs the company from Walnut Creek, California in the San Francisco Bay Area.

How Tend does business

The business model:

  1. Make something genuinely useful
  2. Charge a fair price for it

Tend is bootstrapped by a single founder with no outside investors, which means no pressure to grow fast, cut corners, or answer to anyone but customers.

All revenue comes from paid subscriptions, not from selling your data or showing ads. Simple as that.

What real customers say

All of the 300 households on Tend have felt what you're probably feeling now — relief.

I've really loved Tend and the philosophy of "less is more" when it comes to budget categorization.

Keeping up on categorizing has been the #1 blocker to maintaining a regular spending plan.
