• Paranoia File Encryption is a universal file encryption application for iOS (iPhone/iPad/iPod), brought to you by Paranoia Works. It securely encrypts your private and confidential files or entire folders. P.F.E. works like an archiver, creating a new .enc file after encryption. The original file(s) can be deleted or wiped after the encryption process is completed. This can be done manually or set to be done automatically. • The app guarantees real security by encrypting data using robust encryption algorithms: Blowfish 448 bits, AES 256 bits, RC6 256 bits, Serpent 256 bits, and Twofish 256 bits ciphers. • Steganography: The application offers steganographic features, allowing you to conceal files within a JPEG image. Two algorithms are available: J-UNIWARD and F5. The selected algorithm works with your chosen symmetric cipher to create the final steganogram. • Versions for other systems and platforms are available on the application's homepage (download section - https://paranoiaworks.mobi/download/). • The AES web version is available at: https://pteo.paranoiaworks.mobi/paranoia-file-encryption/ • Free / PRO version differences: The PRO version contains more algorithms - specifically, Threefish 1024bit, SHACAL-2 512bit, and Paranoia C4 2048bit (which is a cascade of Threefish–Serpent–AES–SHACAL2). The free version can decrypt data encrypted by these advanced algorithms, but encryption is exclusive to the PRO version. In addition, the PRO version allows the selection of multiple files and their batch processing. It also provides a key to activate the PRO version of the desktop application: Paranoia File & Text Encryption for PC, Paranoia Text Encryption for PC and S.S.E. File Encryptor for PC
Lens Smudge Detection
Read full descriptionHide full description
This app can detect images taken with dirt or foreign objects on the lens. Dirt refers to anything covering the lens, such as fingerprints or raindrops, which can cause blurring or haze in images. This feature helps you find the best frames from a set of videos or images. The Lens Smudge Detection results display a confidence score from 0.0 to 1.0. This indicates the likelihood that there was dirt or a malfunction on the lens at the time of shooting. A confidence score of 1.0 means there is a very high probability that dirt or foreign objects were on the lens at the time of shooting. Running the app requires a device with A14 Bionic chips(iPhone 12) and later.

Verdict
The clearest difference is ads: Paranoia File Encryption Lite at none against Lens Smudge Detection's shown.

On price and in-app purchases there is nothing between them.
