Free tool questions
- Are these tools free?
- Yes. All tools on this page are free, with no account or payment details required.
- What happens to the files and text I put in?
- Files and text are processed in your browser. The screenshots you check stay on your device, and the text you paste is cleared when you close the tab. Nothing is uploaded from your machine.
- Do I have to use StoreStudio to use these?
- No. Each tool works independently, regardless of which app you use to design or write. Studio and Listing are available when you want to manage more of the work in one place.
- How current are the sizes and limits?
- They come from the same data the editor exports with and the same limits the listing tools check against, so they update when the product does. Every page says the date it was checked against Apple, and each field limit, such as 30 characters for the name, is quoted from Apple with a link.
