# Helmarr vs OpenPlan3D

The clearest difference is in-app purchases: OpenPlan3D at none against Helmarr's 19. OpenPlan3D also leads on review sentiment (100% vs 76%). Helmarr's advantage is update cadence (weekly vs monthly) and ratings volume (172 vs 4). On price, rating, ads and device support there is nothing between them.

Both are free to download. Helmarr sells 19 in-app purchases, starting at $3.99 per month. OpenPlan3D asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Helmarr against 5.0 for OpenPlan3D.
