Overview
When evaluating browser-based tools designed to improve the Polymarket experience, PolymarketOddsConverter (extension) vs PolyTimer presents an interesting contrast in scope and purpose. PolymarketOddsConverter is an open-source browser extension for Chrome and Firefox that performs a single, focused task: converting Polymarket's implied probabilities into decimal odds. Currently listed as coming soon, the project is publicly available on GitHub and targets users who prefer to interpret market data in a traditional odds format rather than as raw probability percentages.
PolyTimer, by contrast, is an actively available tool with a live website at polytimer.fun, delivered as a browser extension that overlays Polymarket pages with time-related enhancements. Its core value proposition centers on countdown timers, local-time conversions, and resolution tracking — helping users understand exactly when markets will close or settle. Where PolymarketOddsConverter is narrowly focused on odds formatting, PolyTimer addresses a broader usability gap around temporal awareness, making it relevant to international traders, casual participants, and anyone who relies on precise timing in their prediction market activity.

When to Choose PolymarketOddsConverter (extension)
PolymarketOddsConverter is worth watching if your primary frustration with Polymarket is interpreting implied probabilities rather than working with the odds formats you already understand. Once released, it should suit users migrating from traditional sports betting or financial markets where decimal odds are the standard. Keep in mind that the extension is not yet publicly released, so users with an immediate need will need to wait or explore the GitHub repository directly.
- You have a background in sports betting or traditional wagering and find probability percentages less intuitive than decimal odds.
- You want a lightweight, open-source tool with a single, transparent purpose and no extraneous features.
- You are comfortable using pre-release or GitHub-hosted software and are willing to wait for or build from the source.
When to Choose PolyTimer
PolyTimer is the stronger choice for users whose main challenge is staying oriented around market resolution timing. It is actively available and designed to reduce the friction of tracking when markets close, particularly for participants outside North American time zones where UTC timestamps can cause confusion. Its on-page integration means there is no need to juggle external dashboards or manually calculate local deadlines.
- You trade or monitor markets across multiple time zones and need accurate local-time countdowns to avoid missing resolution windows.
- You manage several open positions simultaneously and want at-a-glance visibility into which markets are approaching settlement.
- You prefer tools that work directly within the existing Polymarket interface without redirecting you to a separate platform.
Verdict
These two tools solve genuinely different problems and are not direct competitors. PolyTimer is the practical choice right now — it is live, actively maintained, and addresses a real, recurring pain point around timing and resolution awareness for a wide range of Polymarket users. PolymarketOddsConverter fills a narrower niche, serving users who specifically need decimal odds formatting, but its coming-soon status means it cannot yet be evaluated or recommended for immediate use. If timing and resolution clarity matter to your trading workflow, PolyTimer is the clear pick today. If odds conversion is your priority, keep an eye on the PolymarketOddsConverter GitHub repository for its eventual release.
