You do not need a designer, a Figma template pack or a paid tool to ship store screenshots that look professional. What you need is a repeatable process. Here is the one we recommend, from raw capture to upload-ready files, entirely free.
Step 1: Capture clean raw screenshots
Take your captures on a simulator or device at the highest resolution you can. Prepare the app first: fill it with realistic, flattering example content, not "test test 123". Hide anything embarrassing in the status bar or, better, plan to crop it out: the top of the OS chrome is dead pixels for marketing anyway.
Step 2: Know your target sizes before you design
Apple wants 1260 x 2736 for the required 6.9 inch class; Google recommends 1080 x 1920 and caps the ratio at 2:1. The full details are in App Store screenshot sizes in 2026 and Google Play screenshot requirements. The point of knowing this upfront: design once at the source resolution and export down, never upscale.
Step 3: Write the captions first
The caption sells; the screenshot proves. Write one benefit-led line per slide before you touch any design: what does the user get, in the words they would use? Sequence the slides like a story rather than a feature list. Since Apple now reads the text inside your screenshots, your captions also work as keywords, see how caption OCR changes your screenshots.
Step 4: Compose the slides
This is where LookFrame does the heavy lifting, free and without an account:
- Create a preset: background, font, colors. Pick one of the built-in styles or make yours. The preset keeps every slide consistent, which is exactly what separates pro listings from amateur ones.
- Import a screenshot per slide and adjust the framing (crop, zoom).
- Add your captions, up to three lines per slide, styled once for the whole set.
- If you sell in several countries, add your languages and translate the captions per language: localizing screenshots is the single highest-leverage ASO move most indies skip.
Step 5: Export and upload
Export produces every size for every device and language in one click, named by convention, ready for App Store Connect and the Play Console. Before uploading, zoom out and look at your first screenshot at thumbnail size: if the caption is not readable there, rewrite it bigger and shorter.
The short version
Clean captures, captions written before design, one consistent preset, and a tool that exports every required size from a single source. The whole process fits in an afternoon, and none of it requires paying anyone.
