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 the network is there.
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 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, talk to us.
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 moving into productivity. A calendar with no trackers or analytics fits the rest of your suite.
De-Googled Android distros
You ship a phone OS without Play Services. KashCal needs no Google services and works offline from the first launch.
Self-hosting platforms
You sell Nextcloud, Stalwart, Radicale, or your own CalDAV. A branded client you can point customers to 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 the network is there.
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
We build a version of the app with your icon, your name and your colors. Your customers see your brand, not ours.
Your defaults
We preset your CalDAV host, account hints, support links and deep-link domains in your build, so the first launch points at your service.
Sync beaten in production
iCloud, Nextcloud, Fastmail, Radicale, Baikal, Zoho, SOGo, Stalwart, and the rest of the CalDAV long tail, tested against the RFCs and against live servers.
67 languages, ready
Over 900 strings and 50 plurals, translated into every language. Your brand’s own strings get translated on their own, 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 changes a header, a CalDAV server bends a spec, and a recurring event goes wrong. We find it and fix it, so your users don’t have to.
Runs offline, on your screen
Events live on the device, so a wall display or kiosk shows the day when the network drops, then syncs when it returns. It fits a screen on the wall as well as a phone.
Work with us. Win your customers' day.
