PDF Chef helps you read, edit, merge, split, compress and sign PDFs on your device. Organize pages, add text and images, place a handwritten signature, add watermarks or page numbers, and protect PDFs with a password. Convert supported images and documents, and extract text. Results depend on the source file and the selected tool. Normal PDF processing runs on your device. Your documents are not uploaded to a PDF Chef server for processing. Offline tools remain available after their assets have loaded. PDF Chef does not require an account. Review your result before sharing or exporting it. On iOS, the first five successful jobs in each rolling seven-day allowance period are complete jobs that you can save, share and export. The period starts with the first successful job. After five jobs, processing and preview remain available, but saving, sharing and exporting require Pro until the allowance resets. Pro Monthly renews automatically until canceled. Pro Lifetime is a one-time purchase, not a subscription. Both options support Apple Family Sharing. Prices and purchase details appear in the app before you buy. Restore purchases from Settings.

Verdict
The clearest difference is in-app purchases: CAHO at none against PDF Chef's 2. CAHO also leads on iOS requirement (12.0 vs 17.4). PDF Chef's advantage is update cadence (every 9 days vs monthly). On price, ads and device support there is nothing between them.
