Hexer vs Smart NFC

Hexer is a desktop level hex viewer packed with features. It was developed from the ground up for iOS and iPadOS. It is natural and intuitive to use for everyone. It is integrated with the Files app. So you can browse Dropbox, Google Drive, your git repositories, your downloads, your documents in iCloud Drive or your desktop. Or you can just share any file to it. Bytes are highlighted in different colors: Printable characters are cyan, spaces blue, null bytes grey, control characters pink and so on. The colors appear across the binary, hexadecimal, and ascii column — or can just be turned off completely. ▶ Many advanced options • Many popular themes from text editors and terminals • Line numbers (offsets) • Overscroll • Complete control over the formatting of what you copy or share • Column counts in powers of two (8 bytes, 16, 32, ...) or in any number that fits • Interpret bytes as ASCII, ISO Latin 1 or EBCDIC • The UI is navigable by keyboard and there are keyboard shortcuts to toggle almost everything • Further features for you to discover ▶ Search • Search for content in the hexadecimal, ASCII or binary column • Preview results with context and jump to and highlight them in the document • Filter results with Regular Expression and based on case sensitivity • Jump between results with arrow keys ▶ Analysis • Get information about the selection or the entire document • Decode to integers • See byte frequencies • See detected file signatures (magic numbers) • Read metadata like creation date and Unix permissions ▶ The App is made by a real person out of love When you buy the app (no hidden in app purchases) the money goes straight to me to support development. If you have any questions or feature requests you can just write me an email and let me know. I will continue development with many more planned features like editing. ▶ The App is friendly There are no in app purchases, ads, tracking, nor is there any data collected. You buy it once and then use it. Nothing more. Nothing less.

NFC is supported on iPhone 7 or newer only; iPad and iPod Touch do not have the hardware to interact with NFC tags. ----- Read, write, interact, and hack your NFC tags on your supporting iPhone! Smart NFC is one of the first apps to support native NFC writing directly from your device. With numerous custom records to get you started, you'll be writing to most NDEF-formatted NFC tags in no time. Don't have any NDEF-formatted tags? Format them in the Advanced section. Tag-specific features are being added that allow you to edit a tag's memory directly, which opens the doors to all kinds of new features! Tag not scanning? NDEF format new tags from the Advanced section to get them working right! An NFC tag is written with a single "Message" which contains any number of "Records." These records define text, links, and data to be stored on the tag. Most tags can be scanned by holding the top of your iPhone within a few centimeters. A chip is only limited only by its size. As long as the chip is NDEF-formatted (most are, and other formats will be supported in a later version) and it has enough space, the limits are endless! Features: - Read, write, duplicate, erase, and permanently lock NDEF-formatted tags - Monitor a tag's max capacity (usually somewhere between 256-1024 Bytes) - Read, write, and interact with links (https://, sms://, facetime://, mailto:, etc.) - Write a variety of pre-defined Social Media and website records - Read and write text records with multiple language localizations - Use Background Tag Reading to interact with NFC tags without an app. Write a link to a tag and then tap it to your phone. Voila! (Supported on iPhone XS and newer) - Review and rewrite previous messages from your History to another tag - Format factory-programmed tags as NDEF tags in-app (Supports most common tags such as Type 2 and Type 5 NFC tags) - Read and write directly to a tag's memory - Send custom commands directly to a tag - And of course, target your users better by using a tag's unique identifier Extras: - Dark Mode - Privacy: we collect nothing as you use the app. Supported Devices: - NFC scanning is available on iPhone 7 and newer. iPad and iPod Touch do not have the required hardware. - Background Tag Reading is available on iPhone XS and newer. iOS will present a notification for the first valid link stored on a tag. Supported Tags: - Any NDEF-formatted tags - MIFARE Ultralight - NTAG 213/215/216 - NXP ICODE® Tags, ISO 15693 Tags, and Type 5 Tags Future support for: - MIFARE DESFire Limitations: - MIFARE Classic tags are not currently supported by iOS Future features: - Include a tag's ID and/or its read count in a record - Password-protect an NFC chip - Connect to a Bluetooth device Feel free to Tweet feature requests to me at @0xA1EC
