For iOS, Android and Flutter developers
Upwork proposals for mobile app developers
Say which platforms you have actually shipped to, and what happened after the app went live.

What should a mobile developer's proposal cover?
Clients hiring mobile developers are buying reassurance about the parts that come after the build: store review, device fragmentation, and whether the app still works in six months. A proposal that only describes the build is answering half the question they are asking.
Most mobile proposals stop at the stack — Flutter, React Native, Swift — as though the framework were the risk. It rarely is. The client has usually been burned by an app that shipped and then sat unmaintained, or one that failed review twice, or one that ran fine on the developer's handset and nowhere else.
How a mobile proposal gets written here
- 1
Import your history once
Your apps, the platforms you shipped them to and the work behind them go into a profile you fill in once.
- 2
Paste the job post
The generator draws on the apps closest to what the client is describing rather than listing everything you have built.
- 3
Add what you know about the risk
Store review, device coverage, backend dependencies. You know which one matters for this job; edit it in before you send.
An illustrative opening for an app build
You want the existing iOS app rebuilt in Flutter so Android stops being a separate roadmap. The risk in that is rarely the rewrite — it is the push notification and deep-link behaviour that was tuned for iOS and quietly breaks on Android. I moved a booking app the same way last year. The build took six weeks; getting notification handling consistent across both platforms took another two, which I would rather tell you now than discover with you later. Is your current backend already sending to both, or is it iOS-only today?
Illustrative, written for this page rather than taken from a real proposal.
What the generator reads from a mobile profile
Upload a CV or LinkedIn PDF and the profile holds your apps, the platforms behind them, your stack and your work history. Skills are matched semantically, so a job asking for cross-platform work still finds the Flutter and React Native projects rather than needing the exact phrase.
A persona is a saved way of presenting that history, and it means whatever you want it to mean — one for native iOS work, one for cross-platform, one for the backend you also write. Side-Gig includes two; Full-Time and Agency include five.
It will not claim a platform you have not shipped to. If your history is Flutter and the job wants native Swift, the draft says what you have actually done rather than implying otherwise.
Doing this by hand
Open the job, find the nearest old proposal, paste, rewrite the first two lines, check the rate, send. Fifteen to twenty minutes each, and mobile jobs are worse than most because the relevant proof is specific: which platform, which store, which version.
So the shortcut is to describe the stack instead, because the stack is easy to recall and the specific app is not. That is the paragraph the client skims past.
The cost is not really the twenty minutes. It is that the app most likely to win you the job is often not the one you happened to mention last time.
The question every app client is really asking
Who maintains this in six months?
Most app clients have either been through an unmaintained build or have heard about one from somebody who has. The app works, the developer moves on, and then iOS ships a version that breaks the login flow and nobody is left who understands the codebase.
Almost no proposal addresses it, which makes addressing it unusually cheap. You do not have to offer a retainer. Saying what you would hand over — the repo, the store credentials, the build pipeline, a note on what will need attention at the next OS release — answers the fear directly and costs you a sentence.
It also filters usefully. A client who does not care about the answer was going to be a difficult client about handover later; one who cares is telling you they intend to keep the app alive, which is generally the better job.
If you have done a handover like that before, it belongs in your profile as a project detail, because it is exactly the proof this paragraph needs.
Who this is not for
If you have not shipped an app to a store, this will not help much yet. The generator writes from what is in your profile, and store history is the thing mobile clients weigh most.
If you are looking for automated bulk applying, this is the wrong tool: every draft is meant to be edited, and nothing is submitted on your behalf.
And if you are applying for salaried mobile roles through an ATS, you want a keyword-led CV built for a parser rather than a client-facing pitch.
Questions from mobile developers
- Does it understand iOS versus Android versus cross-platform?
- It writes from what your profile says you have shipped. Skills are matched semantically, so a cross-platform job finds your Flutter and React Native work without needing the exact wording.
- Can I keep a native persona and a cross-platform one?
- Yes. Each persona reorders the same underlying history for a different reader. Side-Gig includes two, Full-Time and Agency five.
- Does it submit to Upwork for me?
- No. It drafts, you edit, and you paste it in yourself. Prozilio does not connect to your Upwork account to apply.
- What does it cost?
- A 14-day trial on the Full-Time plan with no card and 15 AI credits, then a free plan with 5 credits a month or paid plans from $8 for 40.
