# -NODE- vs WaveCalc

The clearest difference is ads: WaveCalc at none against -NODE-'s shown. -NODE-'s advantage is update cadence (weekly vs every 2 months) and iOS requirement (11.0 vs 13). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. -NODE- sells 2 one-off in-app purchases and WaveCalc sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

-NODE- ships an update weekly, WaveCalc every 2 months. The most recent releases landed on October 18, 2026 and October 7, 2026 respectively.
