Best Kroo alternatives

#1 alternative

Starling Bank

active

The grown-up UK challenger: bank first, app second.

4.7

London · 4M+ · ~$1.1B raised

8.1Strong

If the question is ‘will this still be here in ten years,’ Starling scores at the top of the UK set. Monzo is more fun; Starling is more bank.

Best for: UK individuals and SMEs who want a real bank, not a wallet.

Licence

UK bank

Protection

FSCS up to £85,000

Monthly

Personal free · Business from £0–£7+

#2 alternative

Monzo

active

UK current account that made banking feel like a group chat.

4.7

London · 11M+ · ~$1.3B raised

8.1Strong

The UK salary account to beat. Pair it with Wise or Revolut if you invoice in euros or dollars. Do not open Monzo expecting a travel-card replacement on the free plan.

Best for: UK residents who want FSCS protection and the best everyday app.

#3 alternative

Atom bank

active

PRA/FCA UK bank. Savings and mortgages. FSCS. Not a Starling-class current account.

4.6

Durham / Newcastle · Savings-and-mortgage scale · Bank capital / BBVA-era shareholders

7.1Solid

Atom bank plc is a UK bank. FSCS applies. The live product is savings, mortgages and some SME lending — not a Monzo current account. Put salary at Starling or Monzo. Put a savings pot here if the rate wins. The purple app is not a licence upgrade for an EMI.

Best for: UK savers and mortgage-shoppers who want a PRA bank, not a current-account lifestyle app.

Licence

UK bank — Atom bank plc

Protection

FSCS up to £120,000 per depositor per authorised firm (scheme cap from 1 Dec 2025)

#4 alternative

Revolut

active

Global money app that finally became a UK bank.

4.7

London · 50M+ · $1.7B raised · ~$45B val.

8.6Strong

The default comparison set for a reason. Treat the UK bank product and the e-money wallet as different legal objects, then Revolut wins most travel and multi-currency briefs. It is not the quietest home for a salary if you want a full-licence high-street feel — that is still Starling or Monzo in the UK.

Best for: People who live in more than one currency and want one app for spend, FX, and extras.

Licence

UK bank (eligible customers)

Protection

FSCS up to £85,000 on UK bank balances; EMI safeguarding on e-money wallets

Monthly

Free · Plus/Premium/Metal/Ultra paid

#5 alternative

Kestrl is a habit layer. Keep a Monzo/Starling/high-street account for the actual deposit. Halal branding does not move FSCS.

Best for: UK Muslims who want a money app that speaks their constraints, with a real bank still underneath.

Licence

App + partner EMI/bank rails

Protection

If a spending account exists, it is partner-EMI or bank — not Kestrl-as-bank

Monthly

Freemium / subscription SKUs — confirm live

#6 alternative

active

US banking for the self-employed: taxes, invoices, and a debit card.

4.8

San Francisco · Self-employed base · Series-era (Allianz x others)

7.3Solid

Found is the freelancer current account. Novo is generic SMB. Relay is multi-entity ops.

Best for: US freelancers who hate QuickBooks more than they hate banks.

Licence
