# PDF Expert vs TurKontrol

The clearest difference is ads: PDF Expert at none against TurKontrol's shown. PDF Expert also leads on chart position (#77 vs unranked). TurKontrol's advantage is update cadence (every 6 days vs fortnightly) and iOS requirement (14.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Expert sells 9 in-app purchases, starting at $9.99 per month and TurKontrol sells 4 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
