# Lumi vs SentiSight.ai

The clearest difference is ads: Lumi at none against SentiSight.ai's shown. SentiSight.ai's advantage is update cadence (every 4 months vs every 54 months) and device support (3 vs 1). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Lumi sells 1 one-off in-app purchase and SentiSight.ai sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Lumi ships an update every 54 months, SentiSight.ai every 4 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
