# Sub5 vs PrimalGPT

The clearest difference is rating: PrimalGPT at 4.9 against Sub5's 3.7. PrimalGPT also leads on review sentiment (74% vs 50%) and update cadence (every 4 days vs fortnightly). Sub5's advantage is ads (none vs shown) and iOS requirement (15.1 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Sub5 sells 2 in-app purchases, starting at $8.99 per month and PrimalGPT sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

PrimalGPT holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: PrimalGPT has 64 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 50% of Sub5's written reviews are positive against 74% of PrimalGPT's.

Sub5 ships an update fortnightly, PrimalGPT every 4 days. The most recent releases landed on September 24, 2026 and October 10, 2026 respectively.
