Read full description

iJuggle is a siteswap generator and animator (Siteswap is a mathematical notation for representing juggling patterns). For more information on siteswap notation, check out siteswap.org. The generator is based off of Jack Boyce's J2 program and allows you to choose between a variety of options for generating siteswaps such as async/sync/passing notation, multiplexing, ground/excited states, and composites. It will also allow you to only list siteswaps that contain or exclude certain throws. The animator is based off of JuggleMaster written by Ken Matsuoka and C++ified by Per Johan Groland. With it you can animate synchronous, asynchronous, and multiplexing patterns. It also allows you to specify juggling styles such as mill's mess, which you can mix with any siteswap.

NFC Tools can read and write your NFC tags with a simple and lightweight user interface. By passing your device near an NFC chip, you can read the data it contains and interact with the content. The "Read" section allows you to see data such as: - the maker of the tag - the type of tag (ex : Mifare Ultralight, NTAG213) - the norm of the tag (ex : NFC Forum Type 2) - the available technology (ex: NFC A) - its serial number (ex : 04:85:c8:5a:40:2b:80) - the size of the tag and of the data on it - if you can write on the tag - all the data on the tag (NDEF format) NFC Tools can record standard information on your tags which will be compatible with any NFC device. For instance, you can store a VCARD to share your contact details easily, open an URL, share a phone number or even a geolocation. The "Write" section let you record standardised data such as: - a simple text - a link to a website - an email - a contact - a phone number - a predefined text message - an address or geolocation - a WiFi or Bluetooth configuration - personalised data - and more... The write function allows you to add as much data as you wish. This way you can record large quantities of information on your tag. The app also allows you to save the contents of your chip for later access. NFC Tools has been tested with the following NFC tags: - NTAG 203, 210, 210u, 212, 213, 213TT, 215, 216, 413 DNA, 424 DNA - Ultralight, Ultralight C, Ultralight EV1 - ICODE SLI, SLI-S, SLIX, SLIX-S, SLIX-L, SLIX2, DNA - DESFire EV1, EV2, EV3 - ST25TV, ST25TA - Felica If you encounter any problem, don’t hesitate to contact us. Notes: - Compatible from iPhone 7. - Use the "compatibility" mode to read/write Mifare Classic tags.

Verdict

The call

The clearest difference is review sentiment: iJuggle at 88% against NFC Tools's 51%. iJuggle also leads on in-app purchases (none vs 1) and rating (4.9 vs 4.6). NFC Tools's advantage is ratings volume (15K vs 12) and update cadence (every 3 weeks vs every 3 months). On price, ads and device support there is nothing between them.
