The clearest difference is rating: When to Post AI at 4.8 against PDF Converter ‣ File Editor's 4.3. PDF Converter ‣ File Editor's advantage is ratings volume (39 vs 6). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. PDF Converter ‣ File Editor sells 3 in-app purchases, starting at $6.99 per 7 days and When to Post AI sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
