# PDF GPT vs StudyPrime

The clearest difference is update cadence: StudyPrime at fortnightly against PDF GPT's monthly. PDF GPT's advantage is iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF GPT sells 3 in-app purchases, starting at $3.99 per 7 days and StudyPrime sells 4 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

PDF GPT ships an update monthly, StudyPrime fortnightly. The most recent releases landed on October 25, 2026 and October 31, 2026 respectively.
