Hetk vs Amie: Calendar Sync vs Calendar App (2026)

Hetk and Amie both help you manage multiple calendars, but they solve the problem in completely different ways. Hetk syncs events between calendar providers. Amie is a calendar app that unifies multiple calendars in one interface. Understanding that difference is key to picking the right tool.

This guide compares both tools side by side so you can pick the right approach for your workflow.

Quick comparison

The core difference: Sync vs. App

This is the fundamental distinction.

Hetk synchronizes your calendars. When you add an event to Google Calendar, Hetk copies it to Outlook and iCloud (or whichever calendars you’ve configured). The events live in all your calendar providers simultaneously. You can open any calendar app — Google Calendar, Outlook, Apple Calendar — and see all your events. Hetk runs in the background; you use your existing calendar apps.

Amie is a calendar application that overlays multiple calendars in one view. Instead of navigating between Google Calendar and Outlook, you open Amie and see all your events in one interface. But the events don’t actually sync to your other calendar providers — Amie fetches them via API and displays them. If you open Google Calendar directly, Amie’s changes won’t appear there.

Which approach is better? It depends on your workflow:

• If you use multiple calendar apps simultaneously (native calendar app on phone, Outlook on desktop, Google Calendar in browser), you want sync. Hetk ensures every calendar stays in perfect alignment.
• If you want one unified view across all providers and you’re willing to switch to a new app, Amie offers a more polished, modern interface with stronger scheduling features.

Sync direction and control

Hetk gives you fine-grained control over sync:

• One-way sync: A → B (events from Google go to Outlook, but Outlook changes don’t go back)
• Bi-directional sync: A ↔ B (changes flow both directions)
• Privacy controls: Strip event titles, descriptions, and attendees when syncing sensitive calendars. Mark synced events as “Busy” without revealing details.
• Identity transform: Synced events show your email as the organizer instead of the original sender.
• Duplicate detection: Prevents the same event from being synced twice if it’s already in the target calendar.

Amie has no sync controls because it doesn’t sync. It does offer powerful scheduling features:

• Availability view: See when you and others are free across overlapping calendars, and find meeting slots instantly.
• Scheduling links: Generate a “find a time” link and share it with others — they pick a slot that works for both of you.
• Smart notifications: Unified reminders across all calendars instead of multiple notifications from different apps.

Bottom line: Hetk is about keeping calendars in sync. Amie is about scheduling and unified availability.

Privacy and data handling

Hetk keeps your data in your calendar providers. Events synced via Hetk are stored in Google Calendar, Outlook, and iCloud — encrypted at rest by each provider. Hetk doesn’t keep a copy of your events (except in flight during sync). You control exactly what gets synced and what details are stripped.

Amie stores event data in Amie’s servers. When you connect Amie to Google and Outlook, Amie reads your events and stores them in its database. If you delete an event in Amie but it still exists in Google Calendar, the event remains in Google — but Amie has a copy of it. This has privacy implications: all your event details (titles, descriptions, attendees) are in Amie’s database. Amie’s privacy policy states it doesn’t sell your data, but your events are centralized in one company’s servers.

Bottom line: Hetk keeps your data federated (in your own calendar providers). Amie centralizes it. If data privacy is a concern, Hetk is safer because your events remain in your existing providers.

Pricing

Hetk:

• Personal ($15/year or $2/month): Up to 3 calendar sources, unlimited sync relationships, bi-directional sync, privacy controls. Early adopter pricing: $10/year or $1/month.
• Professional ($50/year or $6/month): Up to 8 calendar sources, everything in Personal plus priority support. Early adopter pricing: $35/year or $3/month.

Both include a 21-day free trial with full feature access. No credit card required.

Amie:

• Free: View all your calendars in one place, but limited to basic scheduling (only see/suggest availability, no advanced features).
• Paid (~$10/month): Unlimited calendars, advanced scheduling (smart scheduling links, availability blocks, meeting notes), integrations (Slack, Microsoft Teams, Zapier).

Amie charges per month with no annual discount. The free version is useful for testing, but it’s fairly limited — most users upgrade to the paid tier.

Bottom line: Hetk is dramatically cheaper for annual use ($15/year vs ~$120/year for Amie). But Amie’s scheduling features justify the cost if scheduling and availability are critical to your workflow.

Use cases

Use Hetk if:

• You use multiple calendar apps simultaneously (switching between them) and need them all in sync
• You have work and personal calendars that need to stay separate but synced
• You sync client or team calendars and need privacy controls
• You want your calendar data to stay in your existing providers (Google, Outlook, iCloud)
• You need iCloud support (Amie doesn’t support iCloud)
• Budget matters ($15/year is much cheaper than $120/year)

Use Amie if:

• You want one unified calendar interface and are willing to use a new app as your primary calendar
• Scheduling and availability are your main pain points (finding meeting times across calendars)
• You only use Google and Outlook (no iCloud)
• You want advanced scheduling features (smart links, Slack integration, meeting notes)
• You don’t mind your event data being stored in Amie’s servers

Can you use both?

Yes. Some teams use Hetk to sync calendars and Amie for scheduling. For example:

1. Hetk syncs your work calendar to your personal calendar (or vice versa) so both calendars stay in sync.
2. You use Amie to find meeting times because its availability view is faster than switching between calendar apps.

They don’t conflict because Hetk reads/writes to your calendar providers, and Amie overlays the same event data.

Which one should you choose?

Choose Hetk if:

• You use multiple calendar apps simultaneously
• You sync personal and work calendars
• You need privacy controls or sync to iCloud
• You want events synced to your native calendar apps
• Cost is important ($15/yr vs $120/yr)

Choose Amie if:

• You want one unified calendar interface
• You need powerful scheduling features (finding meeting times, scheduling links)
• You’re okay centralizing event data in Amie’s servers
• You only use Google and Outlook
• You don’t mind paying for advanced features
