# Apollo vs Deep Think

The clearest difference is review sentiment: Apollo at 84% against Deep Think's 0%. Apollo also leads on rating (4.7 vs 4.4) and ratings volume (189 vs 14). Deep Think's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Apollo sells 7 in-app purchases, starting at $6.99 per month and Deep Think sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Apollo holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Apollo has 189 ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 84% of Apollo's written reviews are positive against 0% of Deep Think's.

Apollo ships an update every 2 weeks, Deep Think weekly. The most recent releases landed on November 7, 2026 and November 5, 2026 respectively.
