Best Apps to Track Shared Expenses in 2026 (Couples, Roommates, Friends)

“Best app for shared expenses” can mean three different things depending on who’s sharing:

1. Couples merging finances — long-term partners who want a shared dashboard for joint budgeting and goals.
2. Roommates splitting bills — utilities, rent, groceries that cycle monthly with no merging.
3. Friends settling trip / event costs — one-time or short-term expenses that need IOU tracking and final settlement.

Each scenario wants a different tool. The mistake most people make is using a friends-trip app (Splitwise) for couples-budget tracking, or vice versa. Below, the right tool for each case.

The short answers:

• Couples merging finances → Monarch Money. Built for shared finances long-term.
• Roommates splitting bills → Splitwise (free) or a Monarch joint account.
• Friends settling trips → Splitwise (free).

Detailed breakdown below.

Quick comparison

#1 — Monarch Money: Best for couples merging finances

Pricing: $99.99/year ($49.99 first year w/ SMARTMONEY). 7-day free trial.

If you and your partner are sharing finances long-term — joint accounts, shared bills, joint goals — Splitwise is the wrong tool. Splitwise is built for IOUs (“you owe me $20”), not shared dashboards. You’ll outgrow it in a month.

The right tool for shared finances is a budgeting app with proper couples support. Monarch is the strongest pick — both partners get separate logins at no additional cost, both see the same shared dashboard, joint accounts visible to both, individual accounts visible per partner’s choice, and goals tracked together with projected hit dates.

What Monarch handles for couples:

• Joint checking, savings, credit cards visible to both partners
• Each partner’s individual fun-money account (visible per setting)
• Shared bills (rent/mortgage, utilities, insurance, subscriptions) tagged automatically
• Joint goals (emergency fund, vacation, house down payment, retirement)
• AI Assistant — ask “how much have we spent on the wedding so far” in plain English
• Credit score for both partners
• Read-only access for an advisor or accountant

This is what most couples actually need. Splitwise is for the case where you’re not merging.

For couples who are sharing finances long-term, this is the right tool — not Splitwise.

Heads up — Splitwise’s free tier changed in 2025

A 2026 reality that older comparison articles don’t reflect: Splitwise’s free tier now caps you at 3 expenses per day. If you and your roommates split more than 3 transactions in a day (groceries + Uber + utilities + dinner), you’ll either need Splitwise Pro (~$3/month) or one of the alternatives below.

For light usage (a few transactions per week), the free tier still works. For heavy usage (active roommates, frequent shared spending), the cap matters and is why several Splitwise alternatives are now competitive.

#2 — Splitwise: Best for roommates and friends

Pricing: Free tier (functional). Splitwise Pro ~$3/month or $30/year.

Splitwise is the IOU app. It’s purpose-built for “I paid for groceries, you owe me $43” tracking. It does not try to be a budget app. That focus is the strength.

Where Splitwise wins:

• Roommate bills. Add an expense, split it 2/3/4 ways, see who owes whom. Settle up via Venmo/PayPal/Cash App at month’s end.
• Trip expenses. Vacation with friends, multiple people paying for different things — Splitwise calculates the simplified settle-up math at the end.
• Event costs. Wedding party, road trip, concert tickets — anything where multiple people pay for shared things and need to settle.

The free tier is genuinely free for normal use. Pro adds receipt scanning, recurring expenses, and ad-free experience for ~$3/month.

Where Splitwise is the wrong tool:

• Long-term couples who are merging finances (use Monarch instead)
• Anyone wanting a real budget with categories, goals, reports, and forecasting
• Anyone tracking joint accounts with auto-aggregation

For couples who keep separate finances and just need “you paid the electric bill, I paid the internet bill, let’s settle quarterly” — Splitwise is the right tool, not a budgeting app.

#3 — Tricount and similar Splitwise alternatives

Pricing: Free + premium tiers around $3-5/month.

Tricount is the European Splitwise alternative. Functionally similar — IOU tracking, group expenses, settle-up. If Splitwise feels off for some reason, Tricount is the most credible alternative.

For most US users, Splitwise is the default. Tricount is the alternative for users in Europe or those who prefer its design.

#4 — Monarch joint accounts for roommates with budget ambitions

If you and your roommates are serious about a household budget — not just splitting bills, but actually managing the shared utilities and groceries with a budget — you can use Monarch with joint accounts.

Setup:

• Open a joint checking account (most banks support it for roommates with a co-signing arrangement)
• Both roommates contribute monthly to the joint account
• Joint expenses come from the joint account
• Connect the joint account to Monarch with both roommates as users

This is heavier-weight than Splitwise but appropriate when roommates want a real budget for the shared portion. Most roommates don’t need this — Splitwise + Venmo is enough.

#5 — Couples + Splitwise (the hybrid)

Some couples use Monarch for shared finances plus Splitwise for the small “you bought my coffee, I’ll grab dinner” tracking. This works because:

• Monarch handles the major shared finances (mortgage, utilities, joint savings, joint goals).
• Splitwise handles the micro-IOUs that don’t deserve to be in the budget app.

For the couple where one partner pays for things and the other partner reimburses without merging fully, this hybrid works well.

#5 — Settle Up: Best for international travel splitting

Pricing: Free + Premium ~$3/month.

Settle Up is the strongest pick for trip splitting in 150+ currencies. Offline mode means you can log expenses on a remote campsite or while abroad without worrying about connectivity. End-of-trip “settle up” calculates the simplified payment graph — who pays whom, minimizing transactions.

Best fit: International vacations, group trips, festivals, study-abroad cohorts.

#6 — Tricount: Best free Splitwise alternative

Pricing: Free (acquired by bunq).

Tricount is the European Splitwise alternative most users land on after hitting Splitwise’s free tier limit. Functionally similar — IOU tracking, group expenses, settle-up — but free. Receipt OCR is included free (Splitwise Pro-only).

Best fit: Roommates and friends who want Splitwise functionality without the free-tier cap.

#7 — Splid: Best for offline + multi-currency travel

Pricing: One-time purchase ~$5 (no subscription).

Splid is offline-first, supports 150+ currencies, and runs on a one-time payment model. No recurring subscription. Good fit for travelers who want a tool they pay for once and own.

Best fit: International travelers who don’t want a recurring subscription for occasional trip splitting.

#8 — Tab / Plates by Splitwise: Best for restaurant table splitting

Pricing: Free (Splitwise’s restaurant-focused side product).

Restaurant-table splitting with receipt OCR — scan the bill, claim items per person, automatically calculates tax and tip proportionally. Solves the “everyone hand-calculates their share” friction.

Best fit: Group dinners where the bill itemization matters and Venmo-the-host doesn’t work.

#9 — Spliit (open source): Best for one-time event groups

Pricing: Free, no signup required.

Spliit is a web-based, no-account-required Splitwise alternative. Perfect for one-time event groups (bachelor parties, weddings, retreats) where requiring everyone to install an app and sign up is friction. Just share a link; everyone enters expenses; settle up at the end.

Best fit: One-off events, groups with people you don’t expect to share with again, privacy-first scenarios.

Travel & vacation expense splitting (use case deep-dive)

Trip splitting has specific requirements that distinguish it from roommate or couples-finance use cases:

• Multi-currency support. International trips touch USD, EUR, GBP, and local currencies. Settle Up, Splid, and Tricount handle 150+ currencies; Splitwise handles fewer.
• Offline mode. You won’t have signal at every campsite or remote restaurant. Settle Up and Splid work offline; Splitwise free does not.
• Group sizes. Most apps handle 2-10 people fine; weddings and retreats need 20+.
• Settle-up math. Apps that minimize the number of transactions (you pay X, X pays Y, etc.) save real-world hassle. Settle Up’s algorithm is best in class.
• Currency conversion. End-of-trip reconciliation should convert all expenses to a single currency at fixed rates. Settle Up and Splid handle this; Splitwise free uses live rates which can change after the trip.

Recommended trip-splitting stack:

• 2-4 people, domestic: Splitwise free (if under 3 expenses/day cap) or Tricount free.
• 5-15 people, international: Settle Up or Splid for offline + currency support.
• 20+ people, one-time event: Spliit (web-based, no signup).
• Restaurant tables: Tab/Plates for itemized splitting.

Use case decision tree

Are you and the other person(s) merging finances long-term?

• Yes → Monarch Money. Splitwise will frustrate you.
• No → Continue.

Are you a couple who lives together but keeps finances mostly separate?

• Yes → Splitwise free + Venmo/Cash App for monthly settle-up.
• No → Continue.

Are you roommates splitting bills?

• Yes → Splitwise free. Optional: open a joint checking + use Monarch if you want a real budget.
• No → Continue.

Are you on a trip or shared event?

• Yes → Splitwise free. Settle up at the end.
• No → Continue.

Are you tracking ad-hoc IOUs with friends or family?

• Yes → Splitwise free.

The most common mistake: using Splitwise as a couples-finance tool. It doesn’t have categories, goals, reports, or forecasting — it’s purpose-built for IOUs only.

How to migrate from Splitwise to Monarch (for couples who outgrow Splitwise)

If you started with Splitwise and now want a real shared finance setup:

1. Open a joint checking account if you don’t have one.
2. Both partners sign up for Monarch’s free trial. Separate logins.
3. Connect every account — joint and individual.
4. Set up shared categories and goals.
5. Settle the final Splitwise balance, then close out Splitwise (or keep using it for tiny micro-IOUs only).

Most couples complete the transition in 2-3 weeks of parallel running before fully cutting over.

Frequently asked questions

Is Splitwise really free?

Yes — the free tier is fully functional for normal use. Splitwise Pro (~$3/month) adds receipt scanning, recurring expenses, and ad-free experience. Most users never need Pro.

Can Splitwise handle long-term couples?

It can, but the design is for IOUs, not shared dashboards. Couples typically outgrow Splitwise within 6-12 months of merging finances.

Does Monarch have an IOU feature like Splitwise?

Not directly. Monarch tracks shared accounts. For micro-IOUs between two people who otherwise share Monarch, the simplest workflow is to use Splitwise alongside, or just track them in a category called “Personal IOUs” within Monarch.

What’s the best app for roommate utilities?

Splitwise for splitting and settling. Monarch joint account if you want a real budget on top.

What if my partner doesn’t want to merge finances?

Then Monarch as a household tool isn’t the right fit yet. Use Splitwise for shared expenses, each of you uses your own personal budget app, and revisit merging when the relationship state supports it.

Can we use both apps?

Yes — many couples use Monarch for shared finances + Splitwise for tiny IOUs. This is a perfectly normal stack.

What about Honeydue or other couples-specific apps?

Honeydue and similar couples-only apps exist but tend to lack the depth of Monarch (no investment tracking, lighter goals, no AI Assistant). Most couples we know who tried them migrated to Monarch within 6 months.

Is there a free version of Monarch?

No permanent free tier — only a 7-day free trial. Splitwise’s free tier is permanent. For free shared finance tracking, Splitwise is the answer; for free comprehensive budgeting, Empower’s free dashboard is the closest option.

Can we share Monarch with our financial advisor?

Yes — read-only advisor access is included at no extra cost.

What about Zelle / Venmo for splitting?

Zelle / Venmo / Cash App handle the settlement side. Splitwise handles the tracking side (who owes whom). They complement each other.

The bottom line

If you’re a long-term couple sharing finances, Monarch Money is the right tool — Splitwise will frustrate you within a few months. The free 7-day trial is the cleanest test.

If you’re roommates, friends, or a couple who keeps finances separate, Splitwise is the right tool — purpose-built for IOUs, free for normal use.

If you don’t know which you are, you’re probably the first one. Couples who say “we keep finances separate” tend to be 80% merged in practice; the budgeting app catches up to that reality.
