Editor's Review
What it is:
B100 is a Spanish digital bank organised around the idea of financial health rather than product volume. Everything runs through the handset: opening the account, the card, transfers, and the tools that sort what you spend and show where the month is going. There is no branch counter standing behind it.
What you get:
Transactions are grouped automatically so recurring charges become visible instead of blending into a statement, savings goals can be set and funded, and alerts arrive as payments clear rather than weeks later. Card controls live in the app too, which is the quickest route to freezing a card you have mislaid. A 500K+ install figure suggests this reached a genuine audience rather than remaining an experiment.
Where it stops:
The 4.2 average is respectable without being high, and app-only banks tend to shed stars in predictable places: identity verification that fails on the first attempt, support reachable only through a chat queue, and outages that leave customers with nowhere physical to go. It is also firmly tied to one country. Registration expects Spanish residency and the documents that go with it, so the app is close to useless to anyone outside that market.
A sensible choice for people already banking in Spain who want budgeting inside the account instead of bolted on from a separate tool.

Pros
Budgeting tools are part of the account rather than a separate subscription
Freezing a mislaid card takes seconds instead of a phone call
500K+ installs for a young digital bank points to real adoption
Cons
Spanish residency and documentation are effectively required to register
A 4.2 average leaves room for the verification and support complaints that follow app-only banks
No branch network, so an outage removes every route to your money at once
Everything depends on the phone, which is awkward if you lose it abroad
Questions people ask
Can I open an account from outside Spain?
Realistically no. Onboarding is built around Spanish residency and the identity documents that accompany it, and the product is aimed squarely at that market.
Is there a branch if something goes wrong?
No. This is a digital-only bank, so support runs through the app and its remote channels. That is the trade you accept for the lower overheads.
Does the budgeting cost extra?
The categorisation and goal tracking are part of the account rather than a paid add-on. Fees attached to specific banking services are a separate matter and are set out in the bank's own terms.
