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.

Verdict

The call

Subscriptions and Certo are too close to call on the numbers: across 5 compared parameters โ€” price, ads, in-app purchases and device support among them โ€” neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Subscriptions sells 1 one-off in-app purchase and Certo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
