# Brain Explorer vs Time Master

The clearest difference is in-app purchases: Brain Explorer at none against Time Master's 17. Brain Explorer also leads on ads (none vs shown) and review sentiment (100% vs 76%). Time Master's advantage is ratings volume (1.2K vs 6) and chart position (#199 vs unranked). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Time Master sells 17 in-app purchases, starting at $0.99 per 7 days. Brain Explorer asks for nothing beyond the download.

Brain Explorer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Time Master has 1.2K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 100% of Brain Explorer's written reviews are positive against 76% of Time Master's.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on October 16, 2026 and October 27, 2026 respectively.
