Best AI Image Generator for Mobile App Mockups

For mobile app mockups, Ideogram 3.0 is the top choice thanks to its industry-leading text rendering (14 credits/image). FLUX.2 Pro (18 credits) offers superior photorealism when screens need extreme detail.

Budget-conscious creators can use GPT Image 1.5 (18 credits) for decent UI elements with simple text. FluxNote provides all three models plus fast iteration with FLUX Schnell (1 credit).
