# Voice vs True Blocker

The clearest difference is ads: True Blocker at none against Voice's shown. Voice's advantage is device support (3 vs 1) and iOS requirement (15.8.3 vs 18.5). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Voice ships an update fortnightly, True Blocker every 9 days. The most recent releases landed on October 4, 2026 and October 6, 2026 respectively.
