Practical posts on App Store Optimization, release workflow, and the small details that turn an indie launch into something people actually find.
Screenshot A/B testing for indie devs without an A/B test platform
Apple's Product Page Optimization gives you proper A/B tests for screenshots, but only on full-size product pages and only for apps with enough traffic to power the test. Here's a poor-man's playbook that works at indie scale — using Custom Product Pages, storefront splits, and a 14-day measurement window.
Case study: how a meditation app cracked Japan without translating the app binary
A solo dev had a meditation app doing well in the US storefront and nothing in Japan. We localized the metadata, translated the screenshot overlays, and pushed a tiny ASA Discovery campaign. Five weeks later the app was top 50 in JP Health & Fitness. The binary stayed in English the entire time.
The 28-character rewrite: a subtitle change that doubled tap-through for a flatlined app
A productivity app I worked with had a perfectly fine subtitle that was quietly killing it. We swapped 28 characters. Tap-through on the search results page nearly doubled. Here's what we changed, what we measured, and the framework you can copy for your own subtitle.
The English locale trick that triples your App Store reach in 5 clicks
Most indie devs ship only en-US. That leaves five English storefronts — UK, Australia, Canada, India, Singapore — with no metadata, no keywords, and a fraction of the discoverability they could have. Here's how to fix it without doing five times the work.
Case study: rank 80 → rank 4 in 9 weeks on a stalled habit tracker
An indie habit tracker had plateaued at ~30 organic installs a day. We didn't change the product. We didn't run new ads. We rewrote the subtitle, rotated the keywords field, and filled the empty English storefronts. Here's the play-by-play.
ASO keyword tracking 101: what to measure, what to ignore
Most ASO dashboards bury the signal under noise. Here's a stripped-down playbook for what actually matters when you're tracking App Store keywords as an indie dev — and what you can safely skip.
Why I built Asomium
The honest version. I shipped a few indie apps, got tired of the same five tabs every release, looked at the existing tools, and built the one I wished existed. This is what I wanted to fix, what I learned, and where it's going.
