# Vimi vs Strings Learning Lab

The clearest difference is ads: Strings Learning Lab at none against Vimi's shown. Strings Learning Lab also leads on iOS requirement (15.5 vs 17.6). Vimi's advantage is chart position (#150 vs unranked). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Vimi sells 7 in-app purchases, starting at $19.99 per month and Strings Learning Lab sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
