The problem
Subscription billing is designed to cost you money quietly.
Companies count on you not noticing. Most people only catch these mistakes months later — if ever.
Silent price hikes
Your SaaS quietly raises prices by $5/mo. No email. You'd never notice you're now paying $17.
Duplicate charges
Charged twice in 6 days for the same subscription. It happens more than you think.
Forgotten trials
You signed up for a 14-day trial. You forgot. Year one: $96 down. We caught it on day one.
Zombie subscriptions
That tool you used twice in February? Still being charged $45/mo. Quietly eating your budget.
How it works
Set up in 2 minutes. We watch forever.
Connect your inbox
Forward receipts to your private WatchMySubs address, or connect Gmail for fully automatic scanning. Two minutes, done.
We parse every receipt
Our AI reads each email, extracts the vendor, amount, and billing cycle, then compares it to what you paid before.
Get alerted instantly
The moment something looks wrong — a price change, duplicate charge, or trial converting — we email you right away.
What we detect
Five detectors. Running on every receipt.
Most subscription trackers tell you what you pay. We tell you when something is wrong.
Silent price hikes, caught instantly.
Every new charge is compared against your history. If a vendor quietly raised their price — even by a dollar — you get an alert within minutes.
- Any amount, any vendor
- Works on forwarded receipts and Gmail sync
- Saved amount shown so you know the ROI

Zombie subscriptions exposed and cancelled.
If a subscription hasn't generated a receipt in 60+ days, it's probably dead weight. We surface it, show you how much you've paid, and ask if you still need it.
- 60-day inactivity threshold
- Shows total spend since last use
- The single biggest source of savings for most users
Duplicate charges refunded before you notice.
Two charges from the same vendor within 7 days? We flag it immediately. Most vendors refund duplicate charges when asked — and having the receipt evidence makes it easy.
- Detects within minutes of the second charge
- 7-day rolling window per vendor
- You get a copy of the alert to forward to support

Trial-to-paid conversions, caught on day one.
You signed up for a free trial, got busy, and forgot. The moment that trial converts to a paid charge, we alert you — so you decide to keep it or cancel before the next billing cycle.
- Fires the moment the first real charge hits
- Shows trial start date and what you're now paying
- Gives you the cancel link so you can act immediately
