While redesigning Dolphin, I kept returning to a basic question: if we know clearer typography and stronger hierarchy help the people using a healthcare product, why should they have to find and enable those improvements?
Accessibility settings can be valuable when they support individual needs. They become a problem when they are used to hide decisions that should have been part of the default experience: readable type, sufficient contrast, clear labels and predictable interaction patterns.
For Dolphin, that meant increasing the default type size, reducing visual competition and making medication savings easier to scan. The goal was not a separate accessible mode. It was a more usable product for everyone, with room for further preference where needed.
Inclusive design is strongest when it shapes the foundation instead of being added as an escape hatch.
