Is today colder or warmer than yesterday? I start my day with the one question that actually matters when getting dressed. The built‑in weather app is comprehensive, but not built for this exact comparison. Yestoday focuses on what you need, showing yesterday’s and today’s weather side by side in a clean, minimalist view—so you can see the difference at a glance. And for planning ahead, it also includes a 10‑day forecast, perfect if you prep tomorrow’s outfit the night before. -----------
