Pricing
Spew is $4.99 per month, with a 30-day free trial and no credit card required to start. There’s also a one-time $149 lifetime option if you’d rather pay once and be done. Pricing is flat: everyone gets bank sync, subscription detection, the full bill grid, and the forecast.
Rocket Money uses a pay-what-you-want premium model: a free tier with limited features, then a slider where you choose between $4 and $12 per month for full access. Most of the genuinely useful features (subscription cancellation negotiation, premium budgeting, full transaction history) live behind the higher tiers. The cancellation service also charges 40% of the first year of any negotiated savings, separate from the subscription fee.
If you want predictable cost, Spew wins on price. If you want a service that does work for you (canceling subs on your behalf), Rocket Money’s value-per-dollar depends on how much it actually saves you.
Bank sync depth
Both apps connect to your bank through Plaid, the same read-only connection layer used by Venmo, Robinhood, and most US fintech apps. Neither app can move money; they can only read transactions.
Where they differ is what happens after the data lands:
- Spew auto-matches incoming charges to the right bill row in your monthly grid. A Comcast charge applied to your Internet bill, an Amex payment applied to your credit card row. You see the cell turn green; the underlying ledger updates. Anything Spew can’t auto-match goes into a pending inbox you triage in seconds. Smart tagging also learns from your past categorizations and auto-tags new transactions as they sync.
- Rocket Money pulls the same transactions but presents them as a flat list with category tags. You don’t get the bill-by-bill ledger.
For people who care about “did I pay X this month,” Spew’s model is more direct.
Subscription detection
Both apps are good at this. Both will find Netflix, Spotify, the gym, the iCloud upgrade you forgot about.
The difference is what they do next:
- Rocket Money offers to cancel the subscription for you. They’ll negotiate cancellation, sometimes negotiate a lower price. Useful, but they take 40% of one year’s savings as a fee.
- Spew shows you every recurring charge in one view (tagged and untagged), and lets you decide what to do. You cancel yourself, you keep 100% of the savings.
Both approaches are legitimate. If five minutes of self-service cancellation is worth saving 40% of your savings, Spew. If you’d rather pay someone to handle it, Rocket Money.
Forecasting
This is the biggest functional gap.
Spew has a built-in cash-flow forecast. You see your projected income, expenses, and net for the next 24 months, and you can drag sliders to model “what if I buy a house in March?” or “what if I take a pay cut to go freelance?” The forecast updates live.
Rocket Money has a net worth chart, a historical line graph of your assets minus liabilities. That’s it. There’s no scenario modeling, no future projection, no what-if.
If you want a budget app that helps you plan, this is where Spew pulls clearly ahead.
User experience
Both apps look modern. Both are pleasant to use. The mental models are different.
Rocket Money is structured around its core service: “we find your subscriptions and we cancel them.” Most of the UI funnels you toward that flow.
Spew is structured around the monthly bill grid: every bill, every month, all twelve months across. It’s a spreadsheet, but every cell is interactive (click to log a payment, attach a receipt, add a partial payment, drop a note). For people who already keep a Google Sheets budget, the model is instantly familiar.
There’s also a calendar view in Spew that lays out every bill and every payday on the actual month, so you can see your money flow visually. Rocket Money has no equivalent.
Privacy and data handling
Both apps use Plaid for bank access: read-only, encrypted, the standard fintech approach. Neither stores your bank credentials directly.
Rocket Money is owned by Rocket Companies (the mortgage giant) and shares some data with the broader Rocket ecosystem; check their privacy policy for current details if data sharing matters to you.
Spew is independent, doesn’t sell data, and the live demo runs entirely in your browser with nothing saved to a backend. You can see exactly what we collect by reading our code (it’s in our public repo).
Best for
| You should pick… | If… |
|---|---|
| Spew | You want to own your financial picture: see every bill, plan future months, model decisions. |
| Rocket Money | You want a service that cancels subscriptions for you and don’t mind a percentage fee on the savings. |
| Spew | You’re a freelancer, contractor, or have variable income. The forecasting and grid views handle this far better. |
| Spew | You’re a couple or family sharing a budget. Multi-month visibility wins. |
| Either | You just want subscription discovery: both find them well. |
Verdict
Pick Spew if you want a budget tool. The bill grid, the forecast, the calendar view, Plaid autosync with smart tagging, and integrated subscription detection make it more capable as an actual personal-finance dashboard, and pricing stays flat at $4.99/month (or $149 lifetime).
Pick Rocket Money if your real goal is “cancel things I forgot about” and you’d rather pay someone to handle it. That’s a legitimate service and they’re good at it; just know that’s what you’re buying.
There’s no shame in using both. Some people connect both to the same Plaid accounts and let Rocket Money handle cancellations while using Spew for planning. The bank sync is read-only either way; nothing breaks.
