Hey Product Hunt! 👋 I built PostTime Atlas because I kept running into the same problem: most “best time to post” tools only think about one timezone. But if your audience is spread across multiple countries, that advice falls apart fast. PostTime Atlas lets you pick your target countries, rank them by priority (which audience matters most to you), and calculates the optimal shared posting window across platforms like Instagram, TikTok, LinkedIn, and more — accounting for real timezone overlaps, not just a generic “9am is best” rule. It’s 100% free, no signup required, and works in both English and Arabic. Would love your feedback — especially if you manage content for a global or bilingual audience. What features would make this more useful for you?
