If your app is stuck or keeps breaking, plenty of people will tell you they can develop it. The one you want is the person who reads your code first and tells you what they found before they quote a price.
Who can develop an app
Four kinds of people take on app work: a full-time hire, a freelancer, an agency, and a team paid monthly to maintain software. Each has a weak spot when the app is already in trouble.
| Option | Good for | Watch for |
|---|---|---|
| Full-time hire | Full focus and deep knowledge of your product over time | Hiring takes months, and the app again depends on one person |
| Freelancer | Small changes at a flexible cost | Can leave like the last one; rarely offers monitoring or after-hours cover |
| Agency, paid by project | New features | Support between projects is often slow or costly |
| Monthly maintenance team | One team accountable for hosting, code and monitoring | A monthly commitment |
Many businesses mix these. An agency builds features while a maintenance team keeps the app running.[1] A stuck app needs one more skill, which is reading someone else's work and judging it fairly. A company that only builds new software may find it awkward to tell you that the existing code is worse than you thought. It may also have to say that finishing will take twice as long as the last developer promised.[3]
What to ask before anyone writes code
Any agency will say yes to "can you finish my app?" A better question is whether they will review the code first and tell you the truth about what they find, before you commit to more building.[2] Be careful with anyone who quotes a firm price for a finished product before they have opened your repository, the place where the code is stored.[2]
A review of this kind takes one to two weeks, depending on the size of the app.[3] It should end in a report you can read without a technical background. The report should say what is done, what is broken, what is missing, what fixing it takes and roughly what it costs.[3]
What "fix it" can mean
The review decides which of three jobs you have.[2]
- Finish it as it is. The app is mostly done and sound, and needs someone to close it out.
- Keep the good parts and replace the rest. Some of the code is usable and some is not.
- Start again, keeping what you learned. The code is beyond saving, but the requirements, design and data still have value.
An owner who has already spent a lot hopes for the first. Some will be told "we'll just finish it" by a shop that plans to rewrite everything and bill it as finishing.[2] A rewrite is the slowest and most costly option. Rough code often holds business rules and odd cases that took months to find, and keeping them is cheaper than finding them again.[1][2] A rewrite is fair only when the evidence from the review supports it.
Get your keys first
Rescues stall more often on missing logins than on bad code. Before real work can start, you need the code repository, the hosting, the domain registrar, the database and the keys for every paid service the app uses.[2] If a developer has gone quiet, these are often in accounts you have never seen.
Start with the domain, because losing it can take the product and your email offline.[2] Then recover the repository, the hosting and a database export you can open. From then on, create every account in your company's name and add developers as users.[1] Who owns the code a contractor wrote depends on your contract and local law. If that is unclear, ask a lawyer before it becomes a dispute.[1][3]
What it costs and how long it takes
The honest answer is that it depends on what the review finds. One rescue firm publishes ranges that show how wide the spread is. It puts the work at $20,000 to $80,000 when the code is reasonably sound and 20 to 40 percent of the work remains. It puts it at $40,000 to $190,000 when design problems must be fixed before development can go on.[3] The same firm says a sound app that is 50 to 70 percent done can reach production in two to four months, and four to eight months when large parts need to be redesigned.[3] These are one firm's figures. Use them to test a quote, not to set a budget.
Where Moosara fits
Moosara is a software rescue practice run by Robert Lara III. It works with founder-led companies of one to ten people whose software shipped and keeps breaking, or never shipped at all. Moosara brings in skilled developers by interviewing and hiring them, puts sound architecture under the app, and trains the people who will run it. The aim is a stable system that lower-cost developers can maintain, on low hosting costs, so you can launch or shrink the team you pay.
The first step is a direct conversation with Robert about where the app stands, what you have spent, and what you need it to do.
