Free tools for app makers

No account, no upload, no watermark. Both tools run entirely in your browser — they exist because we needed them ourselves.

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.

Privacy policy generator

Answer a few questions and get the privacy policy both stores require, ready to copy, download, or host at a permanent URL.

Why 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.

No account, and no upload. Both tools run entirely in your browser. Your screenshots are read with an object URL and a canvas, and the policy is assembled on the page — nothing is sent to us, so there is nothing for us to store.

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.
