Short answer: To choose an app development company, start by matching your budget to a vendor type: under NT$150,000 usually means a freelancer, NT$150,000–500,000 is best value with a development studio, and only above NT$800,000 do you need a full agency. Before signing, spend 1 hour on 6 checks, above all making sure the app store accounts are registered in your company's name.
The owner of a laundry chain wanted a loyalty-points app and got three quotes: NT$680,000 from an agency, NT$320,000 from a studio and NT$120,000 from a freelancer. He picked the cheapest. By month three, messages went unanswered. The app did launch, but the developer account was in the freelancer's name, so any new vendor had to republish it from scratch, wiping out every review and download. The problem was not the price. It was picking the wrong type of vendor and never checking them.
Direct answer: 3 principles for choosing an app development company
Bottom line: pick the right vendor type first, then verify the specific vendor, and finally make sure the accounts and source code belong to you.
- Principle 1: Type matters more than reputation. Reading more "best app development company" lists is less useful than knowing which type of vendor fits a project of your size.
- Principle 2: Verify for yourself, not just from the pitch. Company registration, court records, live apps and past clients can all be checked before you sign.
- Principle 3: Keep the assets in your name. Developer accounts, source code, servers and domains must be under your company, or you can never switch vendors.
3 vendor types compared: agency, studio and freelancer
Bottom line: for app projects in the NT$150,000–500,000 range, a development studio offers the best balance.
| Factor | App development agency | Development studio | Freelancer |
|---|---|---|---|
| Typical quote | NT$800,000 and up | NT$150,000–800,000 | NT$50,000–200,000 |
| Team and contact | 10+ people, via a project manager | 2–8 people, you talk to the developers | 1 person |
| Main risk | High overhead, small projects get low priority | Limited capacity for parallel projects | Illness, a new job or disappearing stops everything |
| Best for | Large projects integrating many systems | An SME's first app | Small changes, proof-of-concept prototypes |
The quote ranges are estimates based on ScriptWalker's experience and depend on the number of features and the back-end required. The line between an agency and a studio is not the name; it is who actually writes the code and who is accountable when something breaks.
Full checklist: 6 checks in the hour before you sign
Bottom line: you can run all 6 checks yourself, and anything that does not match is a warning sign.
- Check the company registration: On the Ministry of Economic Affairs company registry search, look at the founding date, business scope and responsible person. If the company is under 1 year old, ask more questions.
- Check court records: Search the company name in the Judicial Yuan judgment search. Several disputes over contract work or unpaid fees are a red flag.
- Download the apps they built: Portfolio apps should actually be downloadable. No update in two years and reviews full of crash complaints mean nobody is maintaining them.
- Call 2 past clients: Ask "how fast do they respond when something breaks" and "were there extra charges". If the vendor will not give you a single reference, that is your answer.
- Confirm who actually builds it: Ask whether any work will be subcontracted. If so, the contract must state who is responsible.
- Confirm who owns the developer accounts: The Apple Developer Program costs US$99 a year and a Google Play developer account is a one-time US$25. Both should be registered in your company's name (a D-U-N-S number is required), with the vendor added only as a team member.
Common outsourcing traps: 4 that are specific to apps
Bottom line: app outsourcing traps usually hide in publishing and the back-end, not in the screens.
- The quote covers only one platform: After signing you hear that Android costs extra. With Flutter, one codebase ships both platforms, so ask during quoting.
- App review rejections are not included: If the contract is silent, fixing and resubmitting becomes an extra charge.
- The back-end server is in the vendor's account: Your member data sits in their cloud, and you cannot get it back when the relationship ends.
- Cheap template reskins: A shared template with new colors, which you discover cannot be changed when you want to add features.
Decision checklist: can this app development company be trusted?
Bottom line: if you answer "no" to 2 or more of these 6 questions, get another quote.
- Does the registered company name match the contract?
- Can at least 2 portfolio apps be downloaded, with an update in the past year?
- Will they give you at least 1 past client as a reference?
- Does the quote list iOS, Android, back-end and publishing separately?
- Does the contract state that developer accounts, source code and servers belong to you?
- Are payments tied to milestone acceptance, with the first payment no more than 40% of the total?
FAQ
What is the difference between a development studio and an app development company?
Size and point of contact. At a studio you usually talk directly to the developers; an agency has more specialists but higher overhead.
Is it safe to hire a freelancer to build an app?
Fine for small changes or prototypes, but riskier for a production app, because the project stops if one person stops.
Does the app store account have to be in my company's name?
Yes. If the vendor owns it, switching vendors means republishing the app and losing all reviews and downloads.
How can I tell whether an app development quote is reasonable?
Get 3 quotes on the same requirements and check that platforms, back-end and publishing are itemized. Question any quote that only gives a total.
Call to action: who we are a good fit for, and who we are not
Bottom line: first figure out which type of vendor you need, then decide whether to work with us.
ScriptWalker (a Taiwan-based Laravel/Flutter custom development studio) builds iOS and Android apps together with Flutter and the back-end with Laravel, and keeps the accounts, source code and servers in the client's name. Apps start at NT$150,000, systems at NT$80,000 and websites at NT$15,000.
A good fit: SMEs building their first app, and loyalty or booking apps. Not a good fit: a budget under NT$150,000 that expects full features on both platforms, large projects that need a 20-person team from day one, or simply reskinning a template with your logo. In those cases we will tell you directly to look for a different type of vendor. Not sure how to choose an app development company? We will assess which type you need for free:
