Subscriptions: Subs.Killer
Renewal Dates and Cost Per Use
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Track subscriptions by renewal date, usage count, and cost per use. Find forgotten monthly payments and review fixed costs before the next charge.
Still paying for subscriptions you barely use?
Subs.Killer is a simple subscription tracker that helps you manage prices, renewal dates, and real usage. It automatically shows your cost per use, so every monthly payment becomes easier to review.
Streaming, music, gyms, cloud storage, work tools, memberships, and online services.
See which recurring payments are worth keeping and which ones deserve a closer look.
What Subs.Killer helps you do
Track cost per use
Enter the monthly price and tap "Used!" whenever you use a service. Subs.Killer calculates how much each use actually costs this month.
Find review candidates
Low-usage or high-cost subscriptions are organized automatically, helping you focus on the services that may be wasting money.
Judge by service type
Entertainment apps are reviewed by usage frequency.
Cloud storage and infrastructure services are treated as fixed costs.
Tools, gyms, and utility services are evaluated with context, not just raw usage count.
Review before renewal
Renewal countdowns and reminders help you decide before the next charge arrives.
Keep input lightweight
Add a name, price, and renewal date. Then record usage from the app or Home Screen widget with one tap.
