The most expensive (and time-consuming) approach is to follow platform-specific conventions. Google has one, Apple has one — typically, designers know the guidelines, this is by no means a rockstar skill:D In terms of product design, two concepts need to be built — separately around each OS.
Unlike the multiplatform design, this cross-platform design approach is easier and pretty rapid to execute. Here rather than designing 2 different interfaces (that meet ‘parents’ rules), you design for both platforms SIMULTANEOUSLY and IN A WAY THAT REPRESENTS YOUR PRODUCT.
The easiest way is to:
MVP design is not about being unique or something. To make it data-based (not assumption-based), you can rely on big players’ experiences. Once you acquire initial users, you can tweak it in accordance with given feedback.
With this cross-platform design approach, the design logic remains shared across both platforms — as if you opted for ‘Universal design’ approach. At the same time core functional components (like search boxes or buttons) are designed for each OS separately — as if you followed the ‘Multiplatform design’ approach.
The word ‘Hybrid’ talks for itself here. The design will be a mix of both ‘Multiplatform’ and ‘Universal’ approaches
For MVP development, the hybrid approach is the safest bet — and what’s even greater — this cross-platform app design approach aligns perfectly with the entire React Native philosophy. Since you plan to quickly grab both Android and iOS users, applying this ‘Run everywhere’ approach to UI/UX will do the trick. You won’t go crazy about designing every single button out there and create a product users are familiar to use.
