Know the best time to post on social media, anywhere in the world. When to Post instantly tells you whether now is a peak posting window for your audience, even if they're in a different timezone. A single colored dot gives you the answer at a glance. Green means a peak posting window is happening right now. Orange means it isn't, and the app tells you exactly what's next: "Ends in 18m", "Today 9PM", or "Tomorrow 3AM". -- SEVEN SOCIAL MEDIA PLATFORMS See the best posting times for: • Facebook • Instagram • LinkedIn • TikTok • X • YouTube • YouTube Shorts Each platform includes its own weekly schedule based on peak engagement times. Hide the platforms you don't use to keep the menu clean and focused. -- BUILT AROUND YOUR AUDIENCE, NOT YOUR CLOCK The best time to post depends on where your audience is, not where you are. Choose your audience's location once, and every posting window is automatically converted to your local time. Search by city, country, timezone, or GMT. Whether you're posting from Paris for New York, Sydney for London, or Tokyo for Los Angeles, the app does the timezone math for you. -- WIDGETS AND NOTIFICATIONS Keep the next posting window on your phone (directly on your lock and apps screens) with small and medium widgets. Prefer not to keep checking? Get notified the moment a peak window begins. -- RESEARCH-BASED RECOMMENDATIONS Posting windows are based on published engagement research across billions of social media posts. Studies identify the strongest hours and weekdays for each platform using the audience's local timezone. These are population averages, not guarantees. Every audience is different, so use the suggested windows as a starting point and refine them with your own analytics over time. -- PRIVATE BY DESIGN No account. No sign in. No tracking. Everything ships inside the app, works completely offline, and never sends your data anywhere.
