My app developer left. What do I do first? +
Don't change anything in a hurry. Write down every account you know of: Apple, Google, hosting, domain, payments, email. Then book a call. In the App Check I find the rest and check who can log in where. In the takeover everything moves into your company's name, starting with the store accounts and signing keys, because without them no update can ship.
Can you take over an app someone else built? +
Yes, that's the core of the work. The App Check shows what state it's in. The takeover moves the accounts into your name, produces a fresh build with current tools and ships a store update. After that I run it, or hand it to your team with documentation.
We built our app with AI. Can it go to production? +
Often parts of it can. A prototype proves the idea; for paying customers it usually lacks access rules, backups, logging and a clean path into the stores. I check what holds up and fix the rest at a fixed price. I use AI every day myself: it makes building cheaper; it doesn't make accountability cheaper. I review every line that ships.
Apple rejected our app. Can you get it approved? +
Nobody but Apple can promise approval. I read the rejection, check the app against the guideline it cites, fix what's needed and prepare the resubmission with a clear note to App Review. If the app is a wrapped website, I tell you honestly what it takes to turn it into a real app.
What does the App Check cost, and what do I get? +
$2,000, or $1,100 for the first five clients (until 31 December 2026 at the latest), credited in full if you order the next step within 60 days. One app checked, a traffic-light report within five business days, the most critical gap fixed, and a fixed price for the takeover or rescue in two variants.
Who owns the code and the accounts? +
You do. The code sits in your repository from day one; with each paid milestone, the rights to everything delivered up to that point pass to you. Store, server and domain accounts are registered to your company.
You're one person. What if you drop out? +
Code, accounts and documentation sit with you from day one. There is no named stand-in; instead, every takeover and every build comes with an emergency handbook and an exit plan. In operation both are kept current and a handover is rehearsed once a year, so another experienced developer can take over from the documented state. In operation, work on critical outages starts within 4 hours on business days, on everything else within one business day.
What does it cost to keep the app running? +
App Care is $1,400 a month: OS and SDK updates, security patches, new major iOS and Android versions, store deadlines, monitoring and restore-tested backups. Full Service at $2,900 a month adds releases and bug-fixing. Your Technical Lead at $7,200 a month adds the technical decisions and up to four supplier questionnaires a year. Minimum term three months, six for Your Technical Lead. Hosting is billed at cost.
A bank or large customer is reviewing us as a vendor. Can you help? +
Yes. Buyers ask about access, data location, audit trail and exit. Every operation plan includes a supplier pack with the answers buyers usually ask for, and Your Technical Lead covers up to four questionnaires a year. If the app hasn't been checked yet, start with an App Check. No certificate and no legal advice: prepared answers and evidence.
Can you also build a new app? +
Yes. A first version (MVP) starts at $27,800 and is ready for store submission in 2 to 4 weeks; a market-ready app for iPhone and Android starts at $83,300. After scoping, your offer fixes the price of each milestone in writing. What drives the cost is on the app development cost page.
Fixed price or hourly rate? +
Fixed price per milestone, based on a scope put in writing after scoping. Anything outside that scope is only done through a change order you approve in writing, with its own price. You never get an open-ended invoice.
We have our own engineering team. Does working with you still make sense? +
Yes, for a clearly defined job: an Architecture Review, an App Check of one app, taking over a single app, or a customer's vendor review. I work through the repository and the issue tracker you already use, with written decisions and small, reviewable changes. Your team keeps the final say over its own code base.
