About this app
Stop getting surprised by charges you forgot about.
Every month, millions of pounds disappear in £0.99 iCloud tiers, £14.99 streaming bumps, and forgotten free trials that silently converted. SubSentry is the subscription tracker that actually tells you — loudly, and before it happens.
Pay 99p, once. Track unlimited subscriptions, forever.
WHY SUBSENTRY?
Most subscription trackers make you choose between your privacy and your money:
SubSentry takes a different approach. One-time purchase. No bank linking. No limits. No subscription to manage your subscriptions.
WHAT IT DOES
SubSentry is a manual, private subscription vault. You add your bills, it tracks the renewals, and it alerts you before you're charged.
Weeky Expenditure
Get a weekly notification of the upcoming outgoings for the week ahead.
Renewal Alerts
Get notified days before any subscription renews — you set how many days in advance. No more "I didn't know it was renewing this week."
Free Trial Killer
Signed up for a free trial? SubSentry sends alerts at 5 days, 3 days, 1 day, and the day itself before it converts to a paid plan. Cancel on your terms, not theirs.
Contract Watch
Tracking a broadband deal or gym membership? Set the contract end date and SubSentry tells you when it's time to renegotiate or switch.
Spending Pulse
A day-by-day chart of your monthly cash flow — instantly see your expensive weeks. Know your total monthly and annual spend without doing any maths.
Category Breakdown
See exactly how much of your budget goes to Entertainment, Software, Utilities, and more. Cut with confidence.
BUILT FOR PRIVACY
SubSentry never connects to your bank. There's no account, no email address, no server. Every subscription you add is stored locally on your device using encrypted on-device storage.
If you delete the app, your data is gone. Not archived. Not sold. Gone.
QUICK TO USE
Add a subscription in under 10 seconds. Fill in the name, cost, and renewal date — category colours are applied automatically. Done.
Supports weekly, monthly, quarterly, and annual billing cycles. Handles free trials, paused subscriptions, and long-term contracts.

THE HONEST PRICE
99p. Once.
