# ReciproMeter vs Blurize

The clearest difference is ads: ReciproMeter at none against Blurize's shown. Blurize's advantage is device support (3 vs 1) and iOS requirement (15.5 vs 18.0). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. ReciproMeter sells 1 one-off in-app purchase and Blurize sells 3 in-app purchases, starting at $1.49 per 7 days. Whichever you choose, the download price is not the number that matters.

ReciproMeter ships an update fortnightly, Blurize every 10 days. The most recent releases landed on October 25, 2026 and November 10, 2026 respectively.
