# 3D Snap vs Purchase Memory

The clearest difference is ads: Purchase Memory at none against 3D Snap's shown. Purchase Memory also leads on update cadence (every 9 days vs every 3 weeks) and iOS requirement (16.4 vs 18.0). 3D Snap's advantage is chart position (#170 vs unranked).

Both are free to download. 3D Snap sells 15 in-app purchases, starting at $4.99 per 7 days and Purchase Memory sells 1 in-app purchase, starting at $4.99 per year. Whichever you choose, the download price is not the number that matters.
