Screenshot size checker
Drop in a screenshot and see which App Store and Google Play slots accept it — exact sizes, Play’s 2:1 rule, format and the alpha channel that gets uploads rejected.
Open the toolPrivacy policy generator
Answer a few questions and get the privacy policy both stores require, ready to copy, download, or host at a permanent URL.
Open the toolWhy these two
Both are jobs that block a submission and that nobody enjoys. A store refuses a screenshot without telling you which rule it broke, and it refuses a listing with no privacy policy URL at all — so the fastest way to lose an afternoon is to find out at upload time.
The checker answers the first question against the stores’ own published rules: exact dimensions per slot, Google Play’s 320–3840 px bounds and its 2:1 cap, the PNG/JPEG requirement, and the alpha channel that causes most rejections. The generator answers the second with a policy that covers what both stores ask you to disclose.
They are free because they are the parts of a store submission that should not cost anything. If you want the rest — a full screenshot set from one design, AI listing copy in 30+ languages, a landing page and hosted legal pages — that is what Edok Studio does, and the free plan exports without a watermark.
