# Dot Studio vs TraceLock

The clearest difference is review sentiment: TraceLock at 100% against Dot Studio's 0%. TraceLock also leads on monetization model (free vs free with in-app purchases). Dot Studio's advantage is iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Dot Studio sells 1 one-off in-app purchase and TraceLock sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
