Surplus Review (2026): Pricing, Features & Honest Verdict

TLDR

Surplus is an iOS expense tracker that shows your real leftover spend each month after income, bills, and subscriptions. We found it refreshingly simple and genuinely private, with everything stored on-device via iCloud. Best for: solo iPhone users who hate spreadsheets. Price: Free; Pro from $3.99/mo or $29.99 lifetime. Rating: 7.8/10.

What is Surplus?

Surplus is a personal budgeting app for iPhone, iPad, and Mac that answers one question better than most: how much money do you actually have left to spend this month? It takes your income, subtracts your recurring bills, subscriptions, and upcoming payments, and shows the remaining number front and center. That figure is the whole point of the app, and everything else in the interface bends toward keeping it accurate and visible.

It was built by Omar Inam, an indie developer working under Dev Harvest LLC, and it has quietly earned a 4.8-star rating across 28 App Store ratings. That is the kind of score that comes from a small, loyal base rather than a marketing blitz. Surplus leans hard into Apple-native design: home and lock screen widgets, Siri Shortcuts, and Apple Watch support all ship in the box. Unlike the big-name finance apps that push bank connections and ad-driven upsells, Surplus keeps all your data on your own devices and syncs it through your private iCloud account.

The app launched on iOS and has stayed deliberately narrow ever since. Where many budgeting tools chase feature parity with spreadsheets, Surplus picks a lane: show me a single trustworthy number, and nudge me before bills hit. That focus is why it shows up in conversations about the best YNAB alternatives for people who find YNAB too heavy.

What Are Surplus’s Key Features?

Leftover Spend Widget

The headline feature is the leftover-spend calculation. Surplus looks at your monthly income, then deducts known expenses, subscriptions, and installments to surface a single number you can safely spend. You can pin this to your home or lock screen as a widget, so the figure updates without opening the app. It is a small idea executed well. Instead of asking how much you have spent, which is depressing and backward-looking, it tells you how much you have left, which is actionable. In daily use that reframing genuinely changes spending decisions at the checkout.

Buckets and Bill Reminders

Buckets let you carve your budget into categories like rent, groceries, or savings, which supports popular methods like the 50/30/20 rule. You assign a slice of your income to each bucket and watch it drain through the month. Bill reminders track recurring expenses and due dates so you do not miss a payment or get surprised by an annual renewal you forgot about. Together they turn the app from a passive tracker into something that nudges you before money goes out the door, which is where most overspending actually happens.

Private iCloud Sync

Every transaction stays on your device and syncs across your Apple hardware through iCloud. Surplus stores no personal or transaction data on its own servers, which means no bank logins handed to a third-party aggregator and no data set being mined or sold. For anyone uneasy about linking financial accounts to yet another company, this is the standout selling point. It is genuinely rare among budgeting apps, most of which monetize either subscriptions plus data aggregation or upsells tied to bank connections.

Collections, Reports and CSV Export

Beyond day-to-day tracking, Surplus lets you group related transactions into collections, so a weekend trip or a home project can be tallied on its own without polluting your monthly view. It also includes interactive reports that break down spending over time, plus CSV export if you want to crunch numbers in a spreadsheet or hand them to an accountant. The reporting is clear but intentionally lightweight. It is not trying to replace a full bookkeeping suite, and it does not pretend to.

How Much Does Surplus Cost?

Surplus is free to download and use for the core tracking experience, so you can build a budget and use the leftover-spend widget without paying anything. The paid tier, Surplus Pro, unlocks the full feature set and costs $3.99 per month, $29.99 per year, or $29.99 as a one-time lifetime purchase, all handled as standard in-app purchases through the App Store.

That lifetime option is the real story. Most budgeting apps are subscription-only and the cost compounds fast. YNAB runs $14.99 per month, which is $180 a year, and Copilot is around $13 per month. Paying $29.99 once for Surplus Pro undercuts a single year of either by a wide margin, and after that you never pay again. If you stick with budgeting tools for years, which is the whole point of building a money habit, the math is hard to argue with.

There is no enterprise or team pricing here, and there should not be. Surplus is a single-user personal finance app, and its pricing reflects that focus rather than trying to upsell features you would never use. The free tier is generous enough that plenty of casual budgeters never need to pay, and the lifetime tier removes the subscription fatigue that pushes people to abandon finance apps in the first place.

Who is Surplus Best For?

Use Surplus if you own an iPhone, iPad, or Mac and want a clean, private way to see what you can spend without overthinking it. It suits people who prefer a quick glance at a widget over wrestling with a complex spreadsheet, freelancers with irregular income who need to know their safe-to-spend number, and anyone who would rather pay once than carry yet another subscription. If you have bounced off heavier budgeting apps because they demanded too much setup, Surplus is the gentler on-ramp.

Skip Surplus if you live on Android or Windows, since there is simply no version for you. Skip it too if you need automatic bank-feed importing across many accounts, multi-currency forecasting, or detailed reporting and projections. Power budgeters who want envelope rollovers, shared household budgets, and goal automation will outgrow it quickly. Surplus is deep on one idea, not broad across many.

• Use it if: you want a simple leftover-to-spend number, you live in the Apple ecosystem, and you value on-device privacy.
• Use it if: you are tired of subscriptions and want a one-time purchase you can keep for years.
• Skip it if: you need Android support, full automatic bank syncing, shared budgets, or advanced forecasting.

Best Surplus Alternatives

YNAB

YNAB (You Need A Budget) is the heavyweight of zero-based budgeting, built around the discipline of assigning every dollar a job before you spend it. It is far more powerful than Surplus, with goal tracking, bank syncing, reporting, and a devoted community pushing its method, but it costs $14.99 per month or $109 a year with no lifetime option. Choose YNAB if you want a rigorous system and cross-platform support across web, iOS, and Android. Choose Surplus if you want simplicity, privacy, and a one-time price instead of a recurring bill.

Spendee

Spendee runs on both Android and iOS and adds bank-account syncing in supported regions, with paid plans starting around $2.99 per month. It is the better pick if you need automatic transaction import or use a non-Apple device, and its category visuals are friendly for beginners. Surplus counters with stronger privacy, since nothing ever leaves your iCloud, and that cleaner single-number leftover-spend focus that Spendee dilutes with more dashboards.

Copilot

Copilot is a polished, AI-assisted money tracker for iOS at roughly $13 per month or $95 a year. It offers automatic categorization, net worth tracking, and slick design, leaning much more on live bank connections than Surplus does. If you want hands-off automation and do not mind the subscription, Copilot is excellent and arguably the best premium iOS option. If privacy, manual control, and a low one-time price matter more to you, Surplus is the smarter buy.

Final Verdict: Is Surplus Worth It?

Surplus does not try to do everything, and that restraint is exactly why it works. The leftover-spend widget is genuinely useful in a way that survives daily use, the on-device privacy model is a real differentiator rather than marketing fluff, and the $29.99 lifetime Pro price makes most subscription rivals look expensive by comparison. The 4.8-star App Store rating reflects users who found a tool that fits their habits rather than fighting them, and that is the hardest thing for a budgeting app to pull off.

The limits are clear and worth repeating: iOS and Mac only, mostly manual entry rather than automatic bank feeds, and reporting that stays basic. If any of those are dealbreakers, YNAB or Spendee will serve you better. But for a solo iPhone user who wants a private, no-fuss budget they can buy once and keep for years, Surplus earns its 7.8 and a confident recommendation. It is one of the best-value finance apps on the App Store.
