Finding and killing zombie subscriptions with Spew

The average person wastes $400+ per year on forgotten subscriptions. Spew's detection finds every recurring charge across your accounts and makes cleanup a 10-minute job.

The average person wastes $400+ per year on subscriptions they forgot about or stopped using. Streaming services, gym memberships, app trials that converted to paid, cloud storage you don’t fill, SaaS tools you canceled but didn’t.

Spew’s subscription detection finds every recurring charge across your connected bank accounts and surfaces them for review. Here’s how to run a full audit in under 10 minutes.

How subscription detection works

When you connect a bank via Plaid, Spew scans your transaction history looking for:

Anything matching the pattern gets flagged as a subscription. Spew tags known ones automatically (Netflix, Spotify, Adobe, etc.) and lists unknown ones for you to review.

Accessing your subscriptions

From anywhere in the app:

  1. Click Data Repo in the main nav
  2. Click Subscriptions

You’ll see all detected subscriptions organized into:

Step-by-step audit

Step 1: Review your tagged subscriptions

For each tagged subscription:

Click any subscription to see:

Step 2: Triage untagged recurring charges

For each untagged recurring charge:

This cleans up the list and teaches Spew to recognize it next time.

Step 3: Identify the cut list

After review, mark subscriptions to cancel. Common candidates:

Step 4: Cancel

For each one to cancel:

  1. Open the merchant’s website or app
  2. Find “Account” or “Subscription”
  3. Cancel (might take a few clicks; some intentionally bury the button)
  4. Take a screenshot of the confirmation (Spew lets you attach to the subscription record)

Some require a phone call. Have 5 minutes ready and push through.

Step 5: Track the savings

Spew calculates total monthly savings from cancellations and shows:

Use this to direct the saved money somewhere useful: an emergency fund, a Roth IRA, or an aggressive debt payoff.

The “keep” list

Not every subscription is waste. Keep:

A good rule: if canceling it would genuinely degrade your life or business, keep it. If you can’t tell the difference, you’re not using it enough.

Price tier negotiation

Before canceling, try negotiating. Many services will offer a discount to retain you:

5-minute phone call can save $20-$50/month forever. Not a bad hourly rate.

Annual billing tactic

For subscriptions you’re keeping:

This locks in savings AND forces a yearly review point.

Smart tagging and new subscriptions

After your initial audit, Spew keeps watching:

This means you catch new subscriptions within a month instead of a year.

Integration with the monthly grid

Subscriptions you decide to keep can be added to your monthly grid so they appear in your forecast and monthly tracking.

From the Subscriptions page:

Now it’s tracked the same way as your rent and utilities.

Expected savings

Based on our user data:

Annualized, that’s $400-$1,800/year for most people. See our save $1,200/year guide for how to compound this with other easy wins.

Why this matters

Subscriptions are the silent drain. They don’t hurt in any single month (the $15 feels small) but they compound. $80/month on subscriptions is nearly $1,000/year and nearly $30,000 over 30 years if invested instead at 7%.

One 10-minute audit + quarterly check-ins reclaims that money permanently.
