Funding a mobile app dream on your own in Lisbon

You do not need a company, a team or investors to fund a mobile app dream. Many dreams on cohero are run by one person. Backers look for the same thing either way: a clear goal and someone who shows up.

A mobile app budget must connect screen designs to working features, device testing and a maintainable release. Show usable builds at each stage rather than treating downloads as proof.

  1. 01

    You are the proof

    Put your face in the first photo, explain your background in two sentences and show something you have already made. Backers back people first and plans second.

  2. 02

    Keep the scope small

    The first milestone should fit one person's time and skills. Outsource only what you cannot do, and give those costs their own milestone so Backers see them.

  3. 03

    Protect your time

    Post proof when a step is done, answer chat once or twice a day and keep your story current. A steady rhythm builds more trust than bursts of activity.

Risks to plan for

  • R1

    Feature scope keeps growing

    Extra features can absorb development time before the core flow works. Lock the first build scope in the prototype milestone and keep optional ideas outside its budget.

  • R2

    Device-specific failures

    A build that works on one phone may fail on another screen or operating system. Budget for a defined device test matrix and reserve time for fixes before release preparation.

  • R3

    External service changes

    An app may depend on services with changing limits or interfaces. Identify those dependencies early and include integration checks and a fallback plan in the release work.

Example milestone plan

An example plan for a mobile app dream with a goal of €27,000. Backers fund the whole goal, but each milestone's money stays held until you post the proof and Backers release it.

  1. Milestone 1

    €4,050 · 15%

    Validate the core flow

    Post an interactive screen prototype, a prioritised feature list and anonymised notes from guided usability sessions.

  2. Milestone 2

    €10,800 · 40%

    Build the main features

    Share a recorded walkthrough of a working app build, completed feature checks and a summary of remaining development tasks.

  3. Milestone 3

    €6,750 · 25%

    Test across devices

    Upload a device test matrix, anonymised crash reports and before-and-after evidence for the main issues resolved.

  4. Milestone 4

    €5,400 · 20%

    Prepare the release build

    Post release build screenshots, setup documentation and a maintenance checklist with credentials and private data removed.

How Backers are protected

14-day review per milestone

When proof is posted, each Backer has 14 days to release their share or ask for more. Money not released in time goes back to the Backer.

15% fee, deducted — never added

Backers pay exactly what they choose. The 15% fee comes out of each backing: €100 gives the Dreamer €85. The fee is kept if money is returned.

Gifts, not shares

Backings are gifts. No shares, equity, interest or repayment, and Dreamers keep full ownership. Nothing on cohero is an investment or a loan.

Questions and answers

Can one person really fund a mobile app dream?

Yes. Backers do not require a company. They need to understand your goal and see proof as you go, and a small first milestone is the best way to show you deliver.

Do I need a finished app before creating a funding dream?

You can start with a clearly scoped prototype and development plan. Show which screens are interactive, which features still need code and how later milestones will provide working builds and device test evidence.

Can I share app progress without exposing user data?

Record a demonstration using invented accounts and sample content. Remove credentials from logs and screenshots, and use anonymised issue summaries so Backers can review the build without seeing real user records.
