# AI Cleaner Max vs Device Tester

The clearest difference is monetization model: Device Tester at free with in-app purchases against AI Cleaner Max's subscription. Device Tester also leads on ads (none vs shown) and update cadence (weekly vs every 3 weeks). AI Cleaner Max's advantage is ratings volume (1.9K vs 260) and device support (4 vs 2). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. AI Cleaner Max sells 3 in-app purchases, starting at $3.99 per 7 days and Device Tester sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 3.9 for AI Cleaner Max against 4.0 for Device Tester. That said, the two scores are not equally well evidenced: AI Cleaner Max has 1.9K ratings behind it against 260, so its average is the more settled of the two. Written reviews are what separate them: 52% of AI Cleaner Max's written reviews are positive against 54% of Device Tester's.
