# Deep Dive vs One Question a Day

The clearest difference is update cadence: One Question a Day at every 3 days against Deep Dive's every 3 weeks. Deep Dive's advantage is iOS requirement (13.0 vs 17.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Deep Dive sells 8 in-app purchases, starting at $5.99 per month and One Question a Day sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Deep Dive ships an update every 3 weeks, One Question a Day every 3 days. The most recent releases landed on October 4, 2026 and October 15, 2026 respectively.
