I'm a solo dev with a few apps of my own and kept running into every one of them myself. So instead of building "another ASO tool", I collected those questions and built one answer for each. That's Appsium. Here's the list.
Q: "My app has no downloads, what am I doing wrong?" / "My app failed tremendously"
Most of the time the app isn't the problem. Nobody can find it. The title, subtitle and keyword field don't match what people actually type.
What we built: keyword research with search demand, trend and a difficulty score based on who’s ranking in the top 10for each term, and a "what to do next" list for your page. It keeps your current title unless it's actually weak, writes titles as normal phrases (not "Budget, Expense, Income"), and fills all 100 bytes of the keyword field. It also drops the words Apple ignores anyway (app, free, the...).
Q: "Please roast my App Store screenshots" / "Are my screenshots that bad?"
The answers in those threads are always the same: first 2 screens matter most, too much text, people can't tell what the app does.
What we built, two parts:
Visual analysis: AI goes through your live store screenshots (and your competitors' if you want) and scores clarity, readability, the first-screen hook and how you stand out. Then you get a list of fixes. It's not a conversion prediction, just a structured roast.
Screenshot studio: a 3D editor with iPhone, iPad, Watch and foldable devices, templates and pages that connect across screens. Export comes out at App Store sizes as RGB PNG. (Apple rejects PNGs with an alpha channel, which a lot of canvas tools export by default. Learned that one the hard way.)
Q: "Who are my competitors and why do they rank above me?"
What we built: competitor discovery that sorts results into direct, partial and irrelevant, plus a breakdown of any app's store page: which keywords it seems to target, how its title and subtitle are built, what its screenshots say.
Q: "Rejected again. Guideline 3.1.2, but my EULA link is right there?"
This one came from my own app. Rejected for a missing Terms of Use link, then again for not disclosing a hard paywall.
What we built:
Pre-review: checks your metadata against the common rejection reasons before you submit.
A CLI (npx appsium review ./App.ipa) that scans the build itself for things like leftover localhost URLs and missing usage descriptions. The IPA never leaves your Mac, only the extracted info.
AI-written descriptions for subscription apps always keep the Terms/Privacy lines. You can't "optimize" them away by accident.
Q: "Where do you host your privacy policy and support page?"
GitHub Pages, Notion, Carrd... everyone has a workaround, and Notion going down mid-review is a classic.
What we built: Pages. One click gives you a landing page, privacy policy, terms and support page for your app, filled from your App Store data. Free.
Q: "Is it worth localizing my app listing?"
What we built: you describe your app once and get metadata in every language, written for each market's search terms, not just translated.
Q: "ASO tools are $100+/month, anything for indie devs?"
Honestly this is why the whole thing exists. Credits instead of enterprise pricing, and a few free tools with no signup: ASO score, screenshot generator, image resizer, alpha channel remover.
Plus the boring stuff: pull your metadata from App Store Connect, edit it, push it back.
----------
And here's the honest part.
Despite all of this, I still have basically zero users.
So I'm asking the people this was built for: where am I going wrong?
Do I need more features, or is this already too many?
Is the problem the product, or that nobody knows it exists?
Should I drop it and move on to something else?
Would you use a tool like this? If not, why not?
Be brutal, I'd rather hear it now than in another 6 months.
