# LockToDo vs Clean Language

The clearest difference is review sentiment: LockToDo at 93% against Clean Language's 0%. LockToDo also leads on rating (4.3 vs 1.0) and update cadence (every 3 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. LockToDo sells 6 in-app purchases, starting at $1.99 per month and Clean Language sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
