# GranSample vs Foundry

The clearest difference is review sentiment: Foundry at 100% against GranSample's 40%. Foundry also leads on rating (5.0 vs 4.6). GranSample's advantage is monetization model (free with in-app purchases vs subscription) and ads (none vs shown). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. GranSample sells 1 one-off in-app purchase and Foundry sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Foundry holds the better App Store score, 5.0 against 4.6.
