ZeroTier One for iOS allows you to join ZeroTier virtual networks as VPN connections on your iPhone, iPad, or iPod Touch. ZeroTier creates secure peer-to-peer virtual Ethernet networks that work anywhere. Skip the VPN hassles. Connect hybrid clouds, remote teams, and IoT devices directly with no hardware required. ZeroTier One provides virtual network endpoint functionality for iOS devices. Getting started takes seconds: Just tap '+', enter your network ID and name, and then click ‘join network.’ (Once a network is added you can also join it via the iOS VPN control panel. It will appear there as an available VPN connection.) You can only join one ZeroTier network at once due to an iOS limitation of one VPN connection per network extension app. The app allows you to add multiple networks but if you flip one to 'on' any others currently joined will disconnect. We value your feedback! If you encounter any issues or have suggestions for future improvements, please contact our support team through our website. Thanks for using ZeroTier! Clients for other platforms are available on https://www.zerotier.com/ and source code to ZeroTier's core engine can be found here: https://github.com/zerotier/ZeroTierOne

About

nGeneTime

Features
Read full description

nGeneTime combines a kinetic desk clock with local weather, a monthly calendar watermark, a solar-term-based perpetual calendar with Four Pillars (四柱), and line casting for The Book of Change (周易). IPHONE DESK CLOCK Rotate to landscape for magnetic motion and hourglass-style disappearance effects. • Choose 12-hour or 24-hour time and show or hide seconds. • Choose a compact or full date. • View local weather with Celsius or Fahrenheit temperatures. • Drag and pinch the title, date, and weather to move and resize them. • Adjust weather size directly in Clock Settings. • Edit the title and save a personalized layout. Defaults are 12-hour time, hidden seconds, compact dates, and Celsius. MONTHLY CALENDAR WATERMARK Optionally display the entire current Gregorian month behind the clock. • Drag to move and pinch to resize, or use the Calendar Size slider. • Adjust opacity for a subtle watermark. • Highlight today's date with a selectable color that remains visible as the calendar fades. • Start weeks on Sunday or Monday. • Lock the calendar against accidental movement or resizing. • Reset its position and size independently. The calendar follows the device's local date and time zone. Preferences and layout are saved automatically. PORTRAIT CALENDAR Rotate to portrait for lunar dates, day pillars, current Four Pillars, solar-term transitions, and date-selectable hour-pillar tables. The live Four Pillars display represents the current time. Selecting another date changes the selected-date hour-pillar table. LONGITUDE-TO-TIME GLOBE Rotate, tilt, and zoom the globe. View latitude and longitude; compare the selected time-zone reference meridian with the longitude used for correction; and follow five one-hour longitude guides with corresponding clocks. Simplified civil time-zone boundaries are optional. CALCULATION BASIS Choose Time-zone or Longitude-corrected time. Time-zone applies the selected civil time zone to all four pillars. Longitude-corrected time adjusts the reference using the longitude difference from the selected time-zone reference meridian. With usable location data, the corrected reference applies to the year, month, day, and hour pillars. Latitude positions the globe marker; longitude determines the correction. Without usable location, the selected time-zone basis is used. The year pillar changes at the Beginning of Spring (立春), not January 1. The month pillar changes at its applicable solar-term boundary, not the first day of the Gregorian month. Boundary times appear in the selected time zone. HOME SCREEN WIDGETS • Calendar: Month, lunar dates, day pillars, and the applicable solar-term boundary • Four Pillars: Current hour, day, month, and year pillars • Hour Pillars: Twelve intervals with the current interval highlighted THE BOOK OF CHANGE (周易) Cast lines using the hundredth-second value of a running timer. Odd values create whole lines; even values create broken lines. Six lines form a set, and multiple sets can be reviewed. Line casting and visual review are provided, without a complete digital edition, translation, commentary, or interpretation. APPLE WATCH • Current time and Four Pillars with solar-term-based year and month pillars • Optional longitude-corrected pillar time • Monthly calendar and selected-date hour pillars • Timer presets, custom durations of 1–180 minutes, progress, and vibration patterns • Circular and corner day/hour-pillar complications with active timer countdowns PRIVACY Location is optional and supports longitude correction, globe positioning, and local weather. Weather requests send coordinates to Apple Weather or, if unavailable, Open-Meteo. The calendar may use an IP-based approximate location when Core Location is unavailable. Calendar and pillar calculations run on-device. No account is required. Information is not used for advertising or cross-app tracking.

Verdict

The call

The clearest difference is update cadence: nGeneTime at every 10 days against ZeroTier One's every 2 months. ZeroTier One's advantage is iOS requirement (12.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
