Phones, Macs and other apps

Every app, in the browser

Every web app has a phone layout and installs like an app: in Safari on the iPhone, Share › Add to Home Screen; in Chrome on Android, the menu › Install app. Light, dark or the device's theme, kept with your account. Installing needs HTTPS (or localhost).

Native apps

App	Device	What it does	Source
ionotes	Mac, iPhone, iPad	the clipboard Inbox and screenshots on the Mac, notes everywhere, synced with the ioNotes server and usable offline	ionotes-apps
ioHealthSync	iPhone	copies Apple Health data to the ioHealth server: everything or the types you pick, incremental, in the background	iohealth-apps

Both are built from source with Xcode and XcodeGen (brew install xcodegen, then xcodegen generate); each repository's README has the steps. They sign in with your suite account. Behind Cloudflare Access, ionotes takes a Cloudflare Access service token; ioHealthSync's uploads (/v1/) need a bypass rule or a service token (see Cloudflare).

Calendars and contacts on every device

ioCalendar and ioContacts speak the standards phones and desktop apps already use. Settings › Apps and devices in each app shows the exact addresses to type.

On	ioCalendar	ioContacts
iPhone, iPad, Mac	CalDAV, or the configuration profile from Settings › Apps and devices (one tap, with a device-only app password inside)	CardDAV, or its configuration profile
Android	CalDAV with DAVx⁵	CardDAV with DAVx⁵
Thunderbird, Evolution, GNOME, KDE	CalDAV	CardDAV, LDAP
Google Calendar, Outlook	a private webcal:// subscription link (read-only)	vCard export
Mail apps, desk phones, printers		the LDAP directory (read-only)

Sign these in with your user name and an app password (Settings › Account › App passwords), one per device, so losing a phone means revoking one password. An app password can be limited to the sync protocols only; the ones in the Apple profiles always are. Away from home, phones need HTTPS: see Reverse proxy and HTTPS.
