The short version
- Each has a real cost: Elasticsearch eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements; Structured no monthly view available, only daily and weekly views, limiting ability to preview long-term schedules
- They diverge on capability: Elasticsearch covers Full-text Search, Structured covers Visual timeline.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Elasticsearch
- Eventual consistency model with 1-second default refresh interval, not suitable for real-time transactional requirements
- No support for ACID transactions or rollbacks; updates delete and re-insert documents
- JVM-dependent architecture requires careful memory management and monitoring to prevent garbage collection issues at scale
Structured
- No monthly view available, only daily and weekly views, limiting ability to preview long-term schedules
- Cannot export to Excel, PDF, or other printable formats; only JSON export available on Apple devices
- Calendar import requires Pro subscription (except on web where free import is available)
- Android and web versions significantly lag behind iOS version in features and performance
- One-way calendar sync only; cannot export Structured tasks back to Google Calendar or other external calendar apps

Answered from the vendors’ own pages
Elasticsearch: Is Elasticsearch free?
Yes, Elasticsearch can be deployed as free and open-source software for self-managed installations. Elastic Cloud managed service starts at $16.40 per month, with a free 14-day trial available.
SourceStructured: Is Structured free to use?
Yes, Structured has a free tier that includes timeline tasks, all-day tasks, inbox tasks, subtasks, notes, icons, color coding, drag and drop, and calendar import on web (though calendar import requires Pro on iOS/Android). The app is free to download on iOS, Android, Mac, and web.
SourceElasticsearch: Can I use Elasticsearch without Kibana?
Yes, Elasticsearch is a search engine independent of Kibana. Kibana is a visualization and analytics tool that works with Elasticsearch but is optional. You can use the Elasticsearch API directly for searching.
SourceStructured: What does Structured Pro cost and what features does it add?
Structured Pro is available as a monthly or yearly subscription, or as a one-time lifetime purchase for $99.99 USD. Pro adds Structured AI, calendar import and reminders import (on iOS/Android), recurring tasks, replan functionality, custom notifications, and custom color palettes.
SourceElasticsearch: Does Elasticsearch support real-time indexing?
Elasticsearch indexes data with a refresh interval, typically 1 second. Data becomes searchable after the refresh cycle, making it near-real-time but not instantaneous. This can be configured but impacts performance.
SourceStructured: Can I import my Google Calendar into Structured?
Yes, Structured supports importing calendars from Google Calendar, Outlook, Microsoft Exchange, Yahoo, and AOL. On iOS, it connects through Apple Calendar compatibility. On Android and web, you authenticate with your Google account and select which calendars to sync. This feature requires a Structured Pro subscription.
SourceElasticsearch: What are Elasticsearch's scaling limitations?
Elasticsearch requires careful operational management at scale, including shard balancing, heap sizing, and monitoring. Large clusters can suffer from garbage collection issues and become expensive to operate.
SourceStructured: Can I export my tasks from Structured and in what formats?
On Apple devices, you can export your data as a JSON file through Settings > About > Privacy & Permissions > Export Your Data. However, you cannot export tasks to external calendars, nor can you export to printable formats like Excel or PDF. Export is one-way only.
SourceElasticsearch: Does Elasticsearch support transactions and rollbacks?
No, Elasticsearch does not support ACID transactions or rollbacks. Updates are expensive operations that delete and re-insert documents, making it unsuitable for transactional workloads.
SourceStructured: Does Structured work across all my devices?
Yes, Structured syncs across iPhone, iPad, Mac, Apple Watch, and Android devices. However, users have reported that iCloud synchronization can be unreliable, and the Android and web versions have fewer features and slower performance compared to the iOS version.
SourceStructured: What calendar and reminder apps does Structured integrate with?
On iOS, Structured can import from Apple Calendar, Reminders, Google Calendar, Outlook, Microsoft Exchange, Yahoo, and AOL. On Android and web, it supports Google Calendar. Structured can import events and reminders, but cannot export tasks back to external calendars.
