# Relationship Map AI vs Radar Chart

The clearest difference is ads: Relationship Map AI at none against Radar Chart's shown. Radar Chart's advantage is update cadence (weekly vs fortnightly) and iOS requirement (13.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Relationship Map AI sells 2 in-app purchases, starting at $2.99 per month and Radar Chart sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Relationship Map AI ships an update fortnightly, Radar Chart weekly. The most recent releases landed on October 9, 2026 and October 12, 2026 respectively.
