# Instant Cleaner vs PDF Master

The clearest difference is review sentiment: Instant Cleaner at 71% against PDF Master's 9%. Instant Cleaner also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 2 days vs every 2 weeks). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Instant Cleaner sells 3 in-app purchases, starting at $4.99 per 7 days and PDF Master sells 12 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
