Y+ Calculator vs KumamonCalc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Y+ Calculator
This app calculates the necessary grid spacing for computational fluid dynamics (CFD) simulations. It helps engineers determine near-wall cell height for accurate viscous flow computations. Supports both SI and Imperial units.
- Calculate grid spacing for target y+ values
- Supports viscous CFD computations
- Works in SI or Imperial units
- Resets to sea-level conditions
- Based on established fluid mechanics theory

Y+ Calculator is a handy tool for calculating the grid spacing at a wall to achieve a target y+ value for viscous computational fluid dynamics (CFD) computations. Simply specify the flow conditions, the desired y+ value, and compute your grid spacing. If you are an engineer running viscous CFD computations, achieving a target value for y+ in your grid is essential for both resolved and wall function grids for accurate results. Save time by computing your near-wall cell height for the boundary layer before generating your grid. The Y+ Calculator works in either SI or Imperial units and quickly resets to sea-level conditions. This utility is brought to you by Cadence Design Systems. Note: Computations are based on flat-plate boundary layer theory from Frank M. White’s Fluid Mechanics 5th edition, page 467.

Verdict
The clearest difference is review sentiment: KumamonCalc at 80% against Y+ Calculator's 0%. KumamonCalc also leads on rating (5.0 vs 3.0) and update cadence (every 3 months vs every 8 months). Y+ Calculator's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, ratings volume and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. KumamonCalc sells 1 one-off in-app purchase. Y+ Calculator asks for nothing beyond the download.
KumamonCalc holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews point the same way: 0% of Y+ Calculator's written reviews are positive against 80% of KumamonCalc's.
Y+ Calculator ships an update every 8 months, KumamonCalc every 3 months. The most recent releases landed on October 21, 2026 and October 23, 2026 respectively.
