Mi Bancolombia, the Mobile App Powering 9 Million Colombians

The Mi Bancolombia app from Bancolombia S.A. is Colombia’s biggest mobile banking front door, serving 9 million users across iOS and Android. The app runs in the cloud, processes 1,400 transactions per second, and folds current accounts, savings, credit cards, loans, QR payments and investments into a single yellow-branded screen. It is also the same app Colombians have been downloading, updating and complaining about for years, with a 3.4-star average on Google Play across 33,000 reviews and a 3.3-star rating on Apple’s App Store across 1,100 ratings. Recent updates have leaned into dark mode, instant account opening and a “Pockets” savings feature, while the back end now lets users buy and sell digital euros through Wenia.

Outside Colombia, Mi Bancolombia rarely registers on the banking-app radar, even though it now does the kind of consolidated work most retail banks still spread across a portal, a card app and a separate QR wallet. The sections that follow walk through what the app handles, how it is secured, and what it still pushes back to the web.

The Stack Inside One Yellow Splash Screen

Mi Bancolombia opens with a balance view that looks closer to a messaging app than a bank ledger. That first impression is intentional: the app is, in practice, a re-platformed version of an older one called Bancolombia Personas, redesigned as a single super-app for the bank’s retail and small-business customers.

The numbers behind the rebuild are not modest. Per Bancolombia’s launch announcement, Mi Bancolombia processes 1,400 transactions per second and runs 99 percent of daily transactions that customers used to do across multiple channels. Bancolombia said in the same announcement that the app serves a user base of 9 million. The full app description on Mi Bancolombia’s official store entry and Mi Bancolombia’s iPhone store entry confirms the cloud-based architecture and lists QR payments, Transfiya transfers, account opening, Pockets savings, credit card management and Flypass top-ups among the day-to-day features.

The rest of the surface is broader still, and built on top of a fully cloud-based core. New customers can open a savings account entirely through the app, and the whole onboarding flow is 100% digital.

• 1,400 transactions per second per the launch announcement
• 9 million active users
• 99 percent of daily transactions reachable inside the app

The Banking Surface Behind One Login

The premise of Mi Bancolombia is that everything the bank used to require a branch, an ATM or a separate web portal for now sits inside one signed-in session. Transfers between a customer’s own Bancolombia accounts and transfers to Nequi, the bank’s digital wallet, carry no per-transaction fee inside the app. QR-code payments let users generate, scan and pay at merchants without a physical card, and the app lets users switch individual cards on and off whenever they want. Users can also open a Bancolombia account tailored to them, instantly, and order a credit card 100% online without visiting a branch.

Beyond payments, the app exposes a Pockets savings feature for goal-based saving, lets users pay third-party cards and credits from a single screen, and routes bill registration and payment for utilities, cellphones, transportation cards and Flypass, the electronic toll tag used on Colombian highways, all through one menu. Day-by-day expense tracking groups spending by category, and a points program called Puntos Colombia can be checked without leaving the app. Two integrations are worth naming because they tie the app to the broader group. Transfiya is a real-time interbank transfer network that lets users send and receive money from accounts at other Colombian banks. Wenia is a regulated digital euro platform that Mi Bancolombia plugged in to let users buy and sell digital euros inside the app, accessed through the “Transacciones, Mover activos digitales” menu, per the App Store release notes.

• Account opening and credit-card requests, 100% online
• QR-code generation, scanning and merchant payment
• Pockets for goal-based savings
• Transfiya real-time interbank transfers
• Wenia for buying and selling digital euros
• Flypass, cellphone and transportation-card recharges
• Tu360Compras and Tu360Inmobiliario marketplaces inside the app

Biometric Login and the Trust Layer

Mi Bancolombia lets users sign in with a fingerprint or face scan, with a PIN as fallback. The bank has built its biometric story over time, starting with Nequi, which became the first Colombian mobile financial service to deploy mobile biometrics for authentication in a partnership with US vendor Daon and its IdentityX platform, according to the Daon IdentityX rollout at Nequi.

That capability has since moved into the parent bank’s main app. Underneath the biometric layer, the app encrypts data in transit and lets users request deletion of their data through standard Android and iOS privacy controls, per the disclosures on both app stores. Google Play’s data safety section lists no data shared with third parties, a notable stance for a financial app in a market where aggressive data sharing is common.

The app is Spanish-language only and ships under a free, finance-category listing from seller Bancolombia S.A., with a registered address at Carrera 48 26 85 Avenida Industriales in Medellín. Google Play’s most recent update landed on April 6, 2026, and the iOS build, version 2.36.5, lists Spanish as its only supported language.

From Personas to Mi Bancolombia

The Mi Bancolombia app is the successor to Bancolombia Personas, the previous-generation mobile app from the bank, per the app’s own description.

The migration has been gradual rather than a hard switch, and the bank has kept the original Personas app installed on some users’ phones as a safety net. Per Bancolombia’s launch announcement, the bank has encouraged users to keep the original App Personas installed temporarily, as certain features are still in transition. The new app is fully cloud-based, which the bank credits with faster performance and lower storage requirements on mobile devices. Per the launch announcement, customers can view real-time account balances during transfers, access detailed loan payment histories, and retrieve documents such as statements and certificates from inside the app.

Where the App Still Pushes You Back to the Web

For all the consolidation, Mi Bancolombia is not a full replacement for the bank’s web portal. Detailed loan statements, complex tax-reporting flows and certain certificate-of-account requests still route users to Sucursal Virtual Personas, the bank’s web banking interface. The handoff is smooth for simple tasks but more cumbersome when the underlying document is dense.

Offline use is also limited. Users can view cached balances and card numbers without connectivity, but payments, transfers and bill pay all require a live connection. That constraint shows up in user reviews, where complaints about migration glitches, missing contacts after the app switch, and a customer service path that funnels users to social media channels are common across both stores.

Bancolombia S.A. responds to most of those complaints on Google Play by steering users to its Facebook, Instagram or X accounts in Spanish for follow-up, a pattern repeated across recent reviews.

The Bank Behind the App and Its NYSE Footprint

Mi Bancolombia is published by Bancolombia S.A., which operates from a registered address at Carrera 48 26 85 Avenida Los Industriales in Medellín. The current chief executive, per the SEC prospectus on the proposed holding restructure, is Juan Carlos Mora Uribe, whose name appears on the prospectus under the chief executive title.

The bank is a public company. Per the same SEC prospectus, Bancolombia’s common shares trade on the Bolsa de Valores de Colombia under the symbol BCOLOMBIA and preferred shares trade under PFBCOLOM, while American depositary shares representing those preferred shares trade on the New York Stock Exchange under the symbol CIB. Each ADS represents four preferred shares. The same filing proposes placing Bancolombia under a new holding company named Grupo Cibest S.A., with shareholders set to vote on the change at an April 23, 2025 meeting.

For international investors, that ADR line is the most direct way to take exposure to the Colombian banking story that Mi Bancolombia sits at the centre of. The product is a banking app, not a share, and there is no separate subscription fee for the app itself, with costs following the underlying accounts, cards and standard transfer charges.

Mi Bancolombia is one of several mobile apps Bancolombia S.A. publishes under its Google Play developer account.

• Cibest Capital US
• eTrading Bancolombia
• Bancolombia Negocios
• Inversiones Grupo Bancolombia
• Bancolombia Empresas

Frequently Asked Questions

Who makes the Mi Bancolombia app?

Mi Bancolombia is published by Bancolombia S.A., a Medellín-based bank that has issued stock under the same corporate name for years. The bank’s American depositary shares trade on the New York Stock Exchange under the symbol CIB, and a March 2025 SEC prospectus outlines a proposal to reorganise the bank under a new holding called Grupo Cibest S.A.

Is Mi Bancolombia the same as Bancolombia Personas?

Mi Bancolombia replaced Bancolombia Personas, the bank’s previous retail app. The change has been rolled out gradually rather than as a forced switch, with the bank still recommending that customers keep the old Personas app on their phones until every feature has been moved over.

Does Mi Bancolombia charge a subscription fee?

No. The app itself is free to download and carries no separate subscription, and the standard account and card charges apply for underlying services. Per-transaction fees for transfers and bill payments follow the normal fee schedule, with discounts shown in-app.

Does Mi Bancolombia work outside Colombia?

The app is built for the Colombian market and is published primarily through the Colombian Google Play and App Store channels. It runs in Spanish and ties to Colombian services like Flypass and Transfiya. Colombian users travelling abroad can use it over data roaming, though they will face the same connectivity limits they would at home.

What can users do offline?

Very little. The app caches balances and card numbers so users can view them without a connection, but any action that moves money requires a live link. Payments, transfers, bill pay and QR-code transactions all stall on a spinning wheel if connectivity drops mid-flow.
