SyncWhen is a free scheduling poll tool built for speed. Create a poll with possible time slots in 30 seconds, share a link, and participants vote yes, maybe, or no on each slot. Results update in real time via WebSocket โ€” no page refresh needed.

Unlike older tools, SyncWhen requires no account from anyone (creator or voter), shows zero ads, and includes yes/maybe/no voting free โ€” features competitors paywall. It's built mobile-first and works in 12 languages: English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Turkish, Indonesian, Vietnamese, Arabic.

Recurring polls support weekly or monthly meetings with one shared link. Calendar export to Google, Apple, and Outlook via .ics file. ActionCable-powered live updates mean votes appear instantly as people respond.

Built for teams, study groups, families, and anyone coordinating time across a group without the back-and-forth of email or chat.

Xamarin features and specs

  • Cross-Platform Development
    Xamarin allows developers to write code once and deploy it across multiple platforms (iOS, Android, and Windows), which can significantly reduce development time and effort.
  • Native Performance
    Apps built with Xamarin perform as well as native apps because they leverage platform-specific hardware acceleration and compile directly to native ARM assembly code.
  • Shared Codebase
    With Xamarin, developers can use a single codebase for different platforms, making it easier to maintain and update apps across multiple operating systems.
  • Large Ecosystem
    As part of the broader .NET ecosystem, Xamarin benefits from a large collection of libraries, tools, and developer resources provided by Microsoft.
  • Strong Community Support
    Xamarin has a strong developer community and comprehensive documentation, making it easier for developers to find support and resources.
  • Integration with Visual Studio
    Xamarin integrates seamlessly with Visual Studio, providing a robust development environment complete with debugging, profiling, and unit testing tools.

Possible disadvantages of Xamarin

  • App Size
    Xamarin apps tend to have larger file sizes compared to native apps because of the additional overhead of the Mono runtime.
  • Limited Third-Party Library Support
    While Xamarin supports a wide range of libraries, not all third-party libraries and SDKs are compatible, which might require custom bindings or workarounds.
  • Performance Overhead
    Some performance overhead might still exist compared to fully native applications, especially in complex and resource-intensive apps.
  • Learning Curve
    Developers coming from purely native development backgrounds might face a learning curve when adopting Xamarin, particularly in understanding the shared codebase approach and platform-specific nuances.
  • Platform Limitations
    Certain platform-specific features and UI elements might not be fully supported or might require additional custom code to implement.
  • Licensing Costs
    Although Xamarin itself is open source, enterprise-level features or more advanced tools might require a Visual Studio Enterprise subscription, which can be costly.

Analysis of Xamarin

Overall verdict

  • Xamarin is a good choice for developers who are entrenched in the Microsoft ecosystem and are looking to create cross-platform mobile applications using a shared codebase. Its native performance, extensive library support, and community backing make it a viable option. However, it's crucial to consider the specific needs of your project, including performance requirements and platform-specific features.

Why this product is good

  • Xamarin is a popular open-source platform developed by Microsoft for building cross-platform mobile applications. It allows developers to use a single codebase written in C# to create native apps for Android, iOS, and Windows. Xamarin is known for its integration with the .NET ecosystem, enabling developers to leverage shared code, libraries, and tools across multiple platforms. It offers access to native APIs and performance optimizations, making it a solid choice for developers familiar with C# and the .NET framework.

Recommended for

  • Developers proficient in C# and .NET
  • Teams looking to build native apps with a single codebase
  • Projects where integration with Microsoft services is a priority
  • Enterprises with existing .NET infrastructure aiming to expand into mobile

Questions & Answers

As answered by people managing Xamarin and SyncWhen.

What makes your product unique?

SyncWhen's answer:

SyncWhen is the only free scheduling poll where both creators and voters skip signup, voting is true yes/maybe/no (not just yes/no), and results update live via WebSocket โ€” while staying completely ad-free. It also ships in 12 languages out of the box, including German, Arabic, and Vietnamese, which is rare in this category.

Why should a person choose your product over its competitors?

SyncWhen's answer:

Three reasons: (1) zero friction โ€” no one needs an account, not the organizer, not the participants; (2) real-time results โ€” votes appear instantly without page refresh; (3) it's genuinely free โ€” no ads, no paywalled features, no data sales. Competitors like Doodle lock yes/maybe/no voting, ad removal, and calendar sync behind $6.95+/month paywalls. SyncWhen includes all of it for free.

How would you describe the primary audience of your product?

SyncWhen's answer:

Anyone coordinating time across a group without wanting the overhead of a meeting platform: small teams planning weekly syncs, study groups and classmates, families organizing get-togethers, hobbyists scheduling club meets, and educators running office hours. Mobile-first design means participants can vote from a phone in seconds, which is where most group-chat invites get opened.

What's the story behind your product?

SyncWhen's answer:

SyncWhen started as a reaction to how bloated scheduling polls had become. Doodle used to take 30 seconds โ€” now it's account creation, cookie banners, upsell modals, and ads. The premise: strip it back. One URL, three voting options, real-time results, no friction for anyone. Built as an indie product, 12 locales shipped at launch to reach users who don't get served by US-centric tools.

Which are the primary technologies used for building your product?

SyncWhen's answer:

Rails 8, Vue 3 (Composition API), PostgreSQL, ActionCable for real-time updates, Puma, Propshaft, Solid Queue / Solid Cable, Tailwind CSS v4. Deployed on a self-managed VPS with nginx + Let's Encrypt.
