👋 Hi everyone, and thanks for checking out ASOStacks!
We built ASOStacks because App Store Optimization can be overwhelming. Most developers and indie makers spend hours researching keywords, optimizing listings, tracking competitors, and figuring out what actually improves app visibility.
Our goal is to make ASO simple by bringing the essential tools together in one place, so you can spend less time on research and more time building your app.
Building ASOStacks involved a lot of listening to feedback from indie developers and continuously refining the product based on real-world ASO workflows. We focused on creating a fast, clean experience that's easy to use whether you're launching your first app or managing multiple apps.
We'd love to hear your feedback, feature requests, or any questions you have. We'll be here throughout the day to answer everything.
Thanks so much for your support! 🚀

Looks like a solid free option for indie devs doing ASO without burning credits on paid tools. One thing that would be really useful is a Chrome extension that shows the difficulty and search volume right inside the App Store and Play Store search results while you're actually browsing. Would save a lot of tab switching during keyword discovery sessions.

@graina55903751 Thanks,That's actually a feature we're actively considering. A Chrome extension that overlays keyword difficulty and search volume directly inside the App Store and Google Play would make research much faster. Really appreciate the suggestion!

Took it for a spin on a small indie app and the difficulty scoring actually matched what I was seeing in the store. Rank tracking updated overnight without me refreshing a thing, which is rare.

Finally a free ASO tool that actually shows keyword difficulty scores without making you hand over an API key. The competitor spy feature pulled decent data on a few apps I checked.

The no-API-keys setup is genuinely refreshing, it removes the biggest friction point that usually makes you abandon an ASO tool in the first five minutes. Nice execution on the opportunity scoring too, it feels calibrated rather than arbitrary.

honestly surprised how clean the keyword research feels, like the difficulty scores actually make sense and not just random numbers. the no api keys thing is honestly a nice touch
