What we sell
Our product is AppSign, a web service for iOS development teams. Customers upload an application, choose the iOS version it must be signed for, register their testers, and give those testers access to the build. Applications are stored on our servers and signed in line with Apple's requirements, which saves teams the manual work of doing it themselves.
AppSign is sold directly from appsign.me as a monthly subscription. Published plans are Basic at $20 per month and Pro at $50 per month, with custom Enterprise terms on request. Plans differ by the number of applications, testers, signing requests and storage included.
Who our customers are
Independent iOS developers, studios and QA teams, worldwide. We sell to businesses and individual developers directly; there is no reseller or agency tier, and we do not manage advertising or marketing accounts on behalf of anyone else.
Our name and our domain
The company is Pixel Rainbow Inc.; the product is AppSign. The domain appsign.me is held and operated by the company, and because AppSign is the only product we sell, every company mailbox sits on the product domain rather than on a separate corporate one — [email protected] for customers, [email protected] for legal and compliance.
So our email addresses carry the product name and not the legal name. The legal entity is stated here, in the footer of appsign.me, and in our corporate records, which list appsign.me as the company website.
How the business works
We are a self-serve business with no outbound sales team. Customers find us through search, developer communities and word of mouth, then subscribe on the website without ever speaking to us. Nobody is ever cold-called, and there is no onboarding call to book.
That makes search our primary acquisition channel, so most of our marketing effort goes into written material for iOS developers — guides on signing and distributing builds, documentation, and answers to the questions teams actually run into. Revenue is subscriptions from those readers; the loop closes when we measure which articles earned them.
AppSign Insight — internal content tooling
Marketing for AppSign is one decision repeated: what to write next, and whether the last thing we wrote was worth it. Today that decision is assembled by hand from two piles — how our published pages perform in search, and how much demand exists for topics we have not covered. AppSign Insight is the internal tool we are building to hold both in one place: it lists everything we have published, scores each article against the demand it was written for, and ranks candidate topics.
The three screens below are mock-ups — design concepts for a tool that is still in development. They are not screenshots of a running product, and every figure in them is illustrative rather than live data.
Screen 1 — Published articles, scored
| Article | Target keyword | Monthly searches | Position | Clicks, 28d | Score |
|---|---|---|---|---|---|

| /blog/install-ipa-on-iphone | install ipa on iphone | 14,800 | 18.2 | 96 | 41 |

What Insight is, and what it is not
Insight is internal. Our own marketing people use it to plan writing for appsign.me; it is not part of AppSign, is not sold or licensed, and customers never see it. It reads two sources — our own Search Console property, for how published pages perform, and Keyword Planner demand figures through the Google Ads API, for topics we have not covered yet.
Both are read-only. The tool retrieves search volumes and competition levels for phrases our staff type in; it does not create, change or optimise advertising campaigns, does not manage accounts, budgets or bids, and does not place ads. We do not run Google Ads campaigns, and nothing Insight reads is republished, resold or passed to anyone outside the company.
