Tool comparison
Kalender Sync vs. Amie – design calendar or real sync?
Amie is one of the sleekest calendar apps on the market – calendar, todos and AI meeting notes in one interface. But an app that overlays your calendars is not a sync: outside Amie, your accounts stay separate, and colleagues and booking tools still only see the individual provider. Here's an honest look at what Amie can do, where the product is heading – and when you need real sync instead (or on top).
Background
What can Amie do?
Amie is a design-obsessed productivity app that unites Google and Apple calendars, todo lists and meeting notes in one interface. The product direction is notable: Amie now markets itself prominently on its own website as an "AI Note Taker" – meetings are recorded locally without a bot, summarised and made searchable; calendar and todos run underneath. Pricing sits at $10/month for Personal ($6/month billed annually), $20/month for Pro ($15 annually) and $30/month for Business ($21 annually), with a 7-day trial – there is no permanently free plan. The key point for this comparison: Amie overlays your calendars inside the app, but doesn't copy events between providers.
Strengths
Where Amie is strong
Design and delight
Amie is among the most beautiful calendar apps, full stop – fluid animations, thoughtful details, calendar and todos merging into one day plan. If you like living your week in a single gorgeous interface, you'll be happy here.
AI meeting notes without a bot
Meetings are recorded locally on your device – no bot joins the call. Afterwards you automatically get a summary and action items, plus chat with your own notes. As an AI notetaker, Amie is to be taken seriously.
Calendar + todos + notes in one
One tool instead of three: events, tasks and meeting knowledge live in the same place. For solo users who hate context switching, that's the real appeal.
Where Kalender Sync wins
Where Kalender Sync makes the difference
An overlay is not a sync
Amie stacks your calendars on top of each other – inside the app. Nothing changes in the accounts themselves: your private Apple event still doesn't exist for your company's Google calendar. Kalender Sync genuinely writes events as "Busy" into the other providers. Colleagues, free/busy lookups and booking tools then see the full truth – without your app being involved at all.
Sync is our core, not a substructure
Amie is visibly evolving towards an AI notetaker – its own website now leads with that positioning. Perfectly legitimate, but it means: calendar is a building block there, not the mission. Kalender Sync does exactly one thing, permanently and with focus: synchronising calendars, GDPR-compliant.
Two-way sync and live-sharing into other calendars
Changes flow in both directions, and by invitation you embed your availability live into another person's calendar – as real events, not an ICS subscription. For assistants, colleagues and long-term clients, that's the channel no calendar app offers.
Three visibility levels per sync
You choose per synchronisation: "Busy" only, "Title + time" or full details – with a custom display name for blocked slots. Privacy by design, not by app boundary.
9 provider types instead of Google + Apple
Amie supports Google and Apple calendars. Kalender Sync connects 9 provider types – including Microsoft Outlook/M365, GMX, WEB.DE, mailbox.org, Infomaniak kSuite, CalDAV and iCal feeds. Corporate Outlook worlds and German consumer providers in particular fall through Amie's cracks.
GDPR, German hosting, DPA
Kalender Sync is GDPR- and BDSG-compliant, hosts at Hetzner in Nuremberg and offers a DPA for business customers – a German product under European law. With a US-oriented startup focused on AI recording, that's exactly the question compliance teams will ask.
A permanently free start – and cheaper
Amie starts at $10/month, with no free plan after the 7-day trial. With Kalender Sync, one synchronisation is permanently free, Basic costs €4/month, Business €10/month – with a 14-day Business trial, no credit card.
Decision guide
When should you pick which?
Amie is the right choice if:
- You want a beautiful all-in-one app for calendar, todos and meeting notes.
- AI meeting summaries without a bot are your actual reason to buy.
- Your calendar world lives entirely in Google and Apple.
- US hosting and a subscription from $10/month are no obstacle for you.
Kalender Sync is the right choice if:
- Events should genuinely arrive in other calendar accounts – not just stacked in one app.
- Colleagues, booking tools and free/busy lookups must see your real availability.
- You need two-way sync and live-sharing into other people's calendars – with visibility you choose per sync.
- You want the broadest provider coverage in this comparison: 9 provider types – Google, Microsoft Outlook/M365, Apple iCloud, GMX, WEB.DE, mailbox.org, Infomaniak kSuite, CalDAV and iCal feeds. Kalender Sync is the only tool in this comparison that connects the German providers GMX & WEB.DE.
- GDPR, German hosting and a DPA are mandatory – or you simply want to start for free.
