Two ways in
You bring the audience. We bring the calendar.
A calendar provider who needs an Android app.
You sell calendar storage, sync, or a productivity suite, and your customers keep asking for a native Android client that looks like yours. Ship KashCal under your brand instead of pointing them at a generic CalDAV picker.
A hardware maker who needs software.
You build the device, a wall calendar, a family display, a kitchen screen, and you do not want to also become a software company. You bring the hardware, we bring the calendar. It runs offline out of the box and syncs when it can.
The build-vs-buy math
If you've scoped a native Android calendar, you know what it costs.
Two to four senior Android engineers, a designer, twelve to eighteen months. Then a year of edge-case bugs nobody warned you about: recurrence rules, timezone DST, CalDAV server quirks, and exception events.
Your icon, your name, your colors. Weeks, not quarters. The hard parts are already paid for: sync, recurrence, and RFC compliance.
The difference is the budget you put into work your competitors can't copy.
Who this is for
If one of these is your team, let's talk.
Email & sync providers
You sell calendar storage. Your customers want a native Android client that looks like yours, not a generic CalDAV picker.
Privacy product bundles
You sell VPNs, password managers, or encrypted email, and you are extending into productivity. A calendar that ships with no trackers fits the rest of your suite.
De-Googled Android distros
You ship a phone OS without Play Services. You need a default calendar that respects that and works offline on day one.
Self-hosting platforms
You sell Nextcloud, Stalwart, Radicale, or your own CalDAV. Pointing customers at a polished, branded client is worth more than another support article.
Vertical SaaS with a calendar gap
Field service, healthcare, education, scheduling. You need a calendar feature next quarter, not three roadmaps from now.
Smart display & wall-calendar makers
You build a family display, a fridge screen, or a digital wall calendar on Android. Bring the hardware; the calendar is done. It runs offline and syncs when it can.
Anyone allergic to building one
You looked at the timeline, the hiring, and the maintenance, and decided your team’s time is better spent elsewhere. We agree.
What you get
A calendar, made yours.
Your brand
Your icon, your name, your colors, swapped at build time. The customer never sees ours.
Your defaults
Pre-configured CalDAV host, account hints, support links, and deep-link domains. The first launch already feels like yours.
Sync beaten in production
iCloud, Nextcloud, Fastmail, Radicale, Baikal, Zoho, SOGo, Stalwart, and the rest of the CalDAV long tail, tested against the real RFCs.
67 languages, ready
677 strings and 40 plurals, already translated. Per-brand strings translate incrementally without redoing the rest.
Source access
The full app, not a black-box SDK. Audit it, extend it, or hand it to a security review.
We sweat the sync
iCloud tweaks a header, a CalDAV server bends a spec, and somewhere a recurring event goes sideways. We catch it so your users never feel it.
Runs offline, on your screen
Offline-first by design, so a wall display or kiosk shows the day even when the network blinks, then syncs when it returns. Built to sit on a screen, not just a phone.
Work with us. Win your customers' day.
