I made a tool to find the best time to buy your new phone2024 · theupgraderadar.com · ▲37
A few months ago my Pixel 4A phone was dying so I started thinking about upgrading to a newer model. I didn't want to get hit with buyer's remorse if a price drop happened after buying, due to a new model being announced or released. After digging around, it turns out that understanding the lifecycle of even the most popular phones isn’t that easy. That's why I've made this simple site: keeps tabs on phones lifecycles and gives you a heads-up on upcoming sales seasons to nail your purchase timing.

I built a frontpage for personal blogs▲783
With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
