Made for Apple
Native Swift on Mac, iPhone and iPad. Keyboard-fast, offline-first — and your mail is read on your device, never copied to our servers.
Five modules.
One desk.
One native Apple app, wired deep into Google.
Nothing slips between windows any more.
Calendar
Everything lands here.
Every Google calendar in one grid — plus the mail, tasks and projects you drop on them.
Focus
One thing at a time.
A timer on the one thing that matters today, and the hours written back into your calendar.
The inbox you decide.
Every account in a single list, split the way you decide, with AI that writes the reply.
Projects
See the whole idea.
A map of everything you are building, how the parts connect and how far each one has come.
Tasks
Everything still open.
Group them by priority, day or project, and change anything without ever leaving the list.
Everywhere
Every feature, on all three.
Mac, iPhone and iPad run the very same app, and every change lands on the others at once.
One day. Five tabs. Endless noise.
Your workday shouldn't be a puzzle.
Core5 collapses all five dimensions into a single stream.
The five
Each one earns its place.
Every candidate for a sixth turned out to belong to one of these. That is the design — and the discipline.
01
Calendar
The week at a glance, two-way with Google — down to the colour.
02
Focus
Three columns and a timer that knows what you are working on.
03Mail
Six inboxes that learn from your corrections, not from rules.
04
Projects
Every project as a map, with its work filed against it.
05
Tasks
What is left — as a list, as columns, or as today.
Native
Fast because it is real.
Swift on Apple platforms — not a web page in a costume. Core5 opens with your work already on screen: disk first, network right behind.

On purpose
Only Apple. Only Google.
Core5 refuses to run everywhere — and that refusal is the feature. Two platforms, wired all the way down. Not two hundred integrations, one inch deep.
Fluent in Google
Calendar and Gmail in both directions: edit here, it lands there — same second, same colour, same account. Several accounts at once, each with its own job.
Requires macOS 26 or iOS 26. Google account optional.
Privacy
Your work is yours.
No analytics. No tracking. No advertising identifiers. Nothing sold, nothing shared, and nothing used to train a model — ours or anybody's.
Encrypted, in the EU
Your desk lives in an encrypted database in Ireland, readable only by your account.
Mail stays with Google
Your mail travels straight between your device and Google. None is kept here.
AI only when you ask
Nothing leaves your device until you press the button, and only what you ask.
Put it on your desk.
Free for the five modules. PRO when you want Core5 to write for you.
