# BuildCores vs Voice

The clearest difference is rating: BuildCores at 4.7 against Voice's 1.0. BuildCores also leads on ads (none vs shown) and ratings volume (2.1K vs 1). Voice's advantage is in-app purchases (none vs 13) and update cadence (fortnightly vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.

Both are free to download. BuildCores sells 13 in-app purchases, starting at $3.99 per month. Voice asks for nothing beyond the download.

BuildCores holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: BuildCores has 2.1K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 73% of BuildCores's written reviews are positive against 50% of Voice's.

BuildCores ships an update every 6 weeks, Voice fortnightly. The most recent releases landed on October 24, 2026 and October 21, 2026 respectively.
