The lesson: a narrowly defined interface improvement can produce a clearly observable change in user sentiment.
A banking app’s usefulness also depends on how comfortably people can interact with it. For one respondent in the customer experience survey for ING BANCA MÓVIL Y FINANZAS, the missing feature was specific: dark mode. Their comment captured both the request and the subsequent resolution.
Translated from Spanish, the respondent wrote: “I need you to add dark mode, please. Update: THERE IS DARK MODE NOW, THANK YOU! 🧡”
Control Over the Viewing Experience
The underlying requirement was a choice in how the interface looked. The respondent wanted an alternative display setting while using the app. Whether the motivation was visual comfort, lighting conditions or personal preference, the lesson rests on the expressed need: control over presentation is part of the banking experience.
The friction was equally concrete. A desired interface option was missing from the respondent’s experience. Its subsequent availability addressed that gap, prompting an explicit expression of appreciation.
The Product Lesson: Make Improvements Recognizable
This case offers a useful signal for product teams: a narrowly defined interface improvement can produce a clearly observable change in user sentiment. The respondent returned to acknowledge that the requested capability was available, connecting a feature to a satisfied expectation.
For mobile banking teams, the practical lesson is to evaluate interface preferences alongside transaction features—and make delivered improvements easy to find.
