Verdict
The clearest difference is update cadence: Simple Depression Test at fortnightly against Bipolar Disorder Test's every 8 months. Simple Depression Test also leads on review sentiment (50% vs 40%). Bipolar Disorder Test's advantage is rating (4.7 vs 4.4) and ratings volume (261 vs 13). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Bipolar Disorder Test holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Bipolar Disorder Test has 261 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 40% of Bipolar Disorder Test's written reviews are positive against 50% of Simple Depression Test's, so the app with the better star average is not the one people write more warmly about.
Bipolar Disorder Test ships an update every 8 months, Simple Depression Test fortnightly. The most recent releases landed on October 14, 2026 and September 29, 2026 respectively.
