Overview

Subs.Killer is a subscription tracker that looks beyond what you pay and shows how much you actually use each service. You can see your monthly and yearly charges at a glance, then check the real value through a cost per use based on how often you use them.

Lay out streaming, music, apps, the gym, and everything else that quietly piles up, and compare them side by side. By looking at how much each one costs per use rather than just the sticker price, it becomes far easier to spot the services that are genuinely worth keeping.

Home screen widgets and billing date reminders help make sure payments do not slip past you or get left on autopilot. The whole experience is built to be a simple, low effort way to keep an eye on your spending without it feeling like a chore.

Features

Cost per use, made visible

It calculates a cost per use from how often you use a service, so you can see the real value of a subscription in numbers, not just the price tag.

Home screen widget

Check your active subscriptions and payment status right from a home screen widget, without even opening the app.

Billing date reminders

Get a reminder as the next billing date approaches, so you never miss the moment to review and can avoid renewals you do not really want.

When to use it

When you want to sit down and review all the subscriptions that have crept up over time
When you are on the fence about canceling a service you barely use
When you want to know how much you spend on subscriptions each month
When you want to stop paying for renewals you forgot were coming

FAQ

What can I do with Subs.Killer

You can manage all your subscription charges in one list and calculate a cost per use from how often you use each one. Together with the widget and billing date reminders, it helps you decide what to review.

How is the cost per use actually useful

Two services can cost the same per month, but the one you use constantly and the one you barely touch have very different costs per use. Comparing by cost per use rather than by price makes it much easier to see which subscriptions to cancel.

I am worried I will forget a billing date

Billing date reminders let you know when the next payment is coming up. That gives you a chance to review before it renews, so you are less likely to keep paying for something you no longer use.

What devices can I use it on

It is an app for iPhone, and it supports home screen widgets too. Please check the App Store page for full compatibility details.
