Tips to improve app logo appearance?

Hello, all. Any tips, tricks, or suggestions for making app logos appear crisper?

I have an app launcher with several apps and all the logos appear a bit… blurry. I followed the suggested dimensions for logos (196px x 196px) but the documentation doesn’t provide additional info like approved file types (png, jpg, svg), resolution, etc.

I created the logos in photoshop and exported as png with 72ppi resolution.

What do you folks do to get crisp looking logos?

Hi, have you checked out the help page on this? https://help.appsheet.com/en/articles/943690-brand-the-essentials

196x196 (recommend transparent PNG) for a logo, and 600x600 for a start page, in short.

I have checked this out. My logos conform to stated specs - 196x196, transparent png.

I may just have to try tweaking logos some. Thank you.
