Online scams have never been more convincing. A store that looks real but never ships the order. A text that looks like it comes from your bank. A video of someone who never said those words. These are not aimed only at the careless. They are built to catch anyone, on an ordinary day, in the middle of an ordinary purchase or message. Kiren is a digital safety app from F-Secure, made for exactly these moments. It helps you tell what is real from what is fake, and it keeps watch over your personal information. F-SECURE MOBILE SECURITY IS NOW KIREN Kiren is the next version of F-Secure Mobile Security, built by the same team and completely redesigned. Your existing subscription carries over automatically. Sign in with the same email address you used before and your protection is active. There is nothing to buy again and no change in price.

Conversations with your contacts are never analyzed. • Personal data monitoring: Watches your email addresses, phone numbers, payment cards, and identity documents around the clock. If any of them appear in a new breach, you get an alert with full details and step-by-step guidance on what to do. • Scam Scanner: Upload a screenshot of a listing, an offer, or a photo and Kiren's AI checks it for scam tactics and deepfake manipulation. • Breach Report: Get timely alerts whenever a company, app or service you use has a data breach along with info about how to best secure your data. KEEP YOUR DEVICE IN GOOD SHAPE • Device Health checks that a device lock is set and that iOS is up to date, the two settings that make the biggest difference to everyday safety. • Recent News keeps you informed about data breaches and current scams.

Verdict
The clearest difference is ads: Kiren by F at none against Spam Cleaner's shown. Kiren by F also leads on ratings volume (107K vs 50) and rating (4.6 vs 4.4). Spam Cleaner's advantage is iOS requirement (11.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Kiren by F sells 10 in-app purchases, starting at $2.99 per month and Spam Cleaner sells 2 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Kiren by F holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Kiren by F has 107K ratings behind it against 50, so its average is the more settled of the two.
