An analysis of more than 100,000 software-developer résumés found that 69% of engineers stay at a job less than two years, and 45% last only one to two. At the brand-name shops people cite as the gold standard, it is worse: average tenure at a company like Google has been clocked at roughly 1.1 years, against a broader software average of about four. That number — not the hourly rate — is the one that should decide whether you outsource your mobile app. And almost nobody argues it on that axis.
The cost-arbitrage story is the one that kills apps
The conventional pitch for outsourcing mobile development is a procurement exercise. Find the lowest defensible hourly rate, ideally in a cheaper timezone. Write a specification. Throw it over the wall. Get an app back, ship it, move on. The decision gets made in a spreadsheet where the only variable that moves is the rate, and the winner is whoever quoted $28 an hour instead of $35. This is the version of outsourcing that gives the whole idea its bad name, and it deserves the reputation.
The rate is the most visible number in the deal and the least important one. It tells you what an hour costs. It tells you nothing about who is spending that hour, whether they will still be on your code in eighteen months, or what happens to everything they learned about your product when they roll off to the next account. You are not buying hours. You are buying a relationship with a codebase that has to survive longer than any single contract.
Mobile is never 'done' — and that is the whole argument
Web teams can sometimes get away with build-and-coast for a while. Mobile cannot. Apple and Google each ship a major OS version every single year, on a calendar you do not control, and every release quietly breaks assumptions your app was built on — permissions models, background execution, push behavior, deprecated APIs, new screen geometries, new store-review rules. An app that was perfect at launch is mildly broken twelve months later through no fault of its own. The build is a fraction of the lifecycle; the maintenance is the product.
This is why the spec-over-the-wall model fails specifically and predictably in mobile. The app that dies in the store is rarely the one that was badly built. It is the one nobody owned after launch — where the SDK that compiled cleanly in one OS cycle stopped compiling in the next, the crash rate crept up, the reviews soured, and the original contractors were three projects gone. You did not buy an app. You rented a snapshot.
The real variable is continuity, not geography
The entire in-house-versus-outsource debate is framed around the wrong question — where the engineers sit — when the question that actually predicts outcomes is who is still touching the codebase in year three. Healthy engineering turnover sits somewhere around 5–7% a year; a lot of the industry runs north of 20%, and embedded and specialist teams run higher still. Every departure resets institutional memory. Mobile codebases, with their accumulated platform-specific scar tissue, punish that reset harder than almost anything else.
The cheap body-shop model is built on churn — that is the business model, not a bug. Bodies are interchangeable line items, junior people are rotated onto your account and off it as utilization demands, and the person who understood why your background-sync logic is written that weird way is now on someone else's project. Replacing a working engineer is commonly estimated at six to nine months of their salary once you count the search, the ramp, and the lost context; one staffing study put the time-to-hire alone at around 43 days. You pay that tax every time the vendor's roster turns, and on the cheap end of the market it turns constantly.
What good outsourcing actually looks like
The version worth doing inverts every assumption of the cheap version. You are hiring a dedicated team that stays, that owns the code as if it were theirs, and that treats the engagement as a multi-year partnership rather than a transaction with a delivery date. The right question to a prospective partner is not 'what's your rate' but 'who specifically will be on this, and will they still be on it next year.' If the honest answer is a rotating pool, walk.
This is the lens I cut the whole topic with. At EltexSoft, the boutique studio I run, our voluntary turnover sits under 5% a year against an industry norm well over 20% — of more than 50 engineers hired since 2015, 15 have left voluntarily — and our average client engagement runs about four years. That is not an HR vanity stat; in mobile it is the product. Our mobile group is deliberately deeper-not-wider: shipped work includes an app featured at Apple's WWDC and a coupon app that reached #2 in its App Store category, and a from-scratch build that has crossed roughly two million installs. None of that comes from a low rate. It comes from the same people maintaining the same code through OS cycle after OS cycle.
The unglamorous practices are what make continuity real rather than a slogan. Every pull request reviewed by at least one other senior engineer before it merges, so knowledge is never trapped in one head. A tech lead who is accountable across years, not a coordinator who hands off. On one engagement we placed ten engineers inside a thirty-person org for two and a half years — that is what 'same team, month after month' buys you, and it is the opposite of body-shopping. The phrase 'we'll staff it from our bench' should make you nervous, not comfortable.
'Never outsource your core product' is the other lazy take
The mirror-image consensus is just as wrong: the founder gospel that you must build your core product in-house or you don't really own it. This treats 'in-house' as a synonym for 'committed,' and it is nothing of the sort. Your in-house team is drawing from the exact same labor market with the exact same churn — except now you also carry the recruiting, the months-long ramp, the comp escalation, and the single points of failure. The two-person in-house mobile team is the most fragile arrangement of all: when one of them leaves, and the data says they probably will inside two years, your iOS knowledge or your Android knowledge walks out the door in an afternoon.
Ownership is a contractual question — full work-for-hire code ownership, your repos, your accounts — not a payroll question. You can own your mobile codebase completely while a partner team builds and maintains it, and you can fail to own it in spirit with a salaried team that quietly rewrote half of it the way each new hire preferred. Where the desks are is not the moat. Whether the knowledge persists is the moat.
When outsourcing is genuinely the wrong call
Commit to a position and you have to name its limits. If mobile is your company's entire reason to exist — if the app is the business, not a surface on it — and you can credibly out-retain the market on engineering talent, then build in-house and pay what that costs. A handful of companies are in that position. Most are not. For most, mobile is one important surface among several, the in-house alternative is two contractors and a hope, and the choice is not between outsourcing and some pristine internal dream team. It is between a partner that keeps the same people on your code for years and a churn machine you assemble yourself.
The position
Outsource your mobile app. Then throw away everything the word usually implies. Stop shopping the hourly rate; a four-person team at $25,000–$55,000 a month that stays for three years is cheaper, by every honest measure, than a $28-an-hour roster you have to re-onboard twice a year. Stop writing a spec and walking away from a thing that an OS release will dent within twelve months. Buy the people, the review discipline, and the multi-year commitment — buy continuity, not hours — and the location stops mattering. Get that wrong and it won't matter whether the bodies sat in your office or someone else's. The app rots either way.
