A bill tracker with a payment calendar, for iPhone

Kelo is an iPhone app that keeps your bills and subscriptions in one list and places each charge on a calendar on the day it lands. It adds up what this month already owes, handles bills that repeat every few weeks, months or years, and with Premium reminds you before each due date.

Three questions a bill tracker should answer

How much is due this month? Which day does each bill land? Which bills repeat on something other than a monthly cycle? A printable bill tracker or a spreadsheet answers the first two if you update it every month. You still have to remember to look, and to move each quarterly bill to its next date.

How Kelo keeps track

  • Each bill on its day. Add the amount and the cycle once. Kelo works out every charge date and rolls it forward: water every two months, car insurance once a year, the gym every four weeks. The full calendar comes with Premium.
  • The month’s total in advance. The home screen shows what this month already owes, and a widget shows it without opening the app.
  • A reminder before the due date. With Premium, Kelo notifies you 1 to 14 days before each charge.
  • No bank connection. Kelo works from the bills you enter and never asks for your bank login. Why that matters for subscriptions.

Bills that aren’t monthly

A bill due every four weeks charges you 13 times a year. The billing cycle changes the yearly total, and a tracker that only understands “monthly” gets it wrong:

Cycle Charges a year
Every week 52
Every two weeks 26
Every four weeks 13
Every month 12
Every two months 6
Every three months 4
Every six months 2
Every year 1

Kelo counts every charge on its real date, so over a full year the bill due every four weeks adds up to 13 charges, not 12.

If a printable works for you, keep it. An app makes sense when you want the reminder and the running total without updating anything.

What it costs

Kelo is free to start: your first recurring expenses and as many one-off expenses as you want. Premium costs $4.99 a month or $29.99 a year on the US App Store. It unlocks unlimited recurring expenses, reminders, the full calendar, budgets and goals, automations and sync.

Facts checked on

Loose ends

What's the simplest way to keep track of bills?

Write each bill down once with its amount and how often it repeats, then check a single monthly total. Kelo does this on iPhone: it places each bill on a calendar and adds up what the month already owes.

Can Kelo handle bills that aren't monthly?

Yes. Pick a common cycle or set your own, counted in weeks, months or years.

Does Kelo pay my bills?

No. Kelo tracks your bills and, with Premium, reminds you before each one. You pay them the way you already do.

Do I need to connect my bank?

No. Kelo never asks for your bank login.

Is the calendar free?

No. The full calendar comes with Premium: $4.99 a month or $29.99 a year on the US App Store. Free, you can add your first recurring expenses and see what this month already owes on the home screen.
