THIS WEEK'S BLOG POST

​Recording a Physical iPhone for App Preview Videos​

App Preview Videos can have an impact on App Store conversion, but also help in app marketing. Unfortunately, it's not always easy to create these from a physical device, which is something you want if your apps only run on a real iPhone. This week's article shares you how you can create a video with a custom background, ratio, and device bezels.

WHAT I'M WORKING ON

Reddit Optimization

While I'm mostly having some time off with the family, enjoying Texel (the Swift Island for those that know!), I've also been working on some Reddit optimization.

Being active on Reddit is something I wanted to do more for a while, but I lacked time and attention to optimize for it. I'm now building a Cloudflare worker which notifies me in popular Swift-related subreddits for posts that should interest me.

Setting up such monitor (I'm using IFTTT with a webhook and its MCP) allows you to more efficiently contribute. It's not recommended to monitor and post links to your apps whenever a related thread appears, as you risk being banned for weeks or even months. However, being active in relevant subreddits will automatically expose you to potential customers, and also builds up credibility to sometimes post backlinks to your apps.

Reddit threads show up in Google and friends of mine generate a lot of leads from several long-running posts. Absolutely worth investigating this if you're trying to market your apps, especially as you'll be able to find niece audiences by looking for related subreddits.
