I’m planning to build an iOS app for my small business but I’m overwhelmed by all the different iOS mobile app development services out there. I’m not sure what to look for in terms of skills, portfolio, pricing, or timelines, and I don’t want to waste money on the wrong team. Can anyone share tips or criteria for evaluating iOS app developers, or recommend what questions I should ask before hiring a service provider?
Had to pick an iOS team for a small biz app last year. Here is what helped me cut through the noise.
-
Start with your goal and scope
Write 1 page with
• What the app does, in plain language
• Who will use it
• Must have features vs nice to have
• Target launch date
This keeps quotes comparable. If your brief is vague, prices jump all over the place. -
Skills to look for
For iOS native apps, ask if they use:
• Swift and SwiftUI or UIKit
• Xcode
• Experience with App Store submission, TestFlight, provisioning profiles
Check if they have experience with:
• Push notifications
• In app purchases or subscriptions
• Secure login and basic backend APIs
If you need a cross platform app, ask about React Native or Flutter, but make sure they have shipped at least 3 apps with it. -
Portfolio checks
Ask for:
• 3 live apps in the App Store, with links
• What they did on each app (design, backend, only iOS)
• Screenshots of analytics or user numbers if they can share
Install those apps. Check:
• Speed and smooth scrolling
• Crashes
• Login and checkout flows
If their own work feels slow or buggy, skip them. -
Reviews and references
Look at:
• Clutch, Upwork, Google reviews
• How old the reviews are
Ask for 2 client contacts. Ask those clients:
• Did they hit deadlines
• How they handled bugs after launch
• If there were surprise costs -
Pricing models
Common options:
• Fixed price for a clear scope
• Hourly rate with time tracking
For a small business app, fixed price for MVP often works best.
Ask for a breakdown:
• Design
• iOS dev
• Backend / API
• QA and testing
• Launch support
Get a simple scope document and payment schedule. Example:
• 30% at start
• 40% at first test build
• 30% at App Store submission -
Typical cost ranges (rough ballpark, US market)
• Simple app, a few screens, no complex backend: 8k to 20k
• Medium app, login, API, payments, push: 20k to 60k
If you see 1k quotes for a full custom app, assume trouble.
If you see 150k for a basic catalog app, they target larger clients. -
Timeline
For small biz MVP:
• 2 to 4 weeks design
• 4 to 10 weeks dev and testing
If they promise a full app in 2 weeks, ask what they plan to skip. Usually QA or proper architecture. -
Contract must haves
• Source code belongs to you after full payment
• Access to repo (GitHub, GitLab, etc)
• Milestones with clear deliverables
• Post launch support terms
Example, 1 to 3 months bug fixes included
Avoid vendors who refuse to give you the source code or want to own the App Store account. -
Red flags
• Vague answers about tech stack
• No live iOS apps in store
• All communication only on WhatsApp, no email or ticket system
• They say yes to every feature without pushing back on scope
A good team will say “drop this feature for phase one” to protect budget and schedule. -
How to shortlist
Talk to 3 to 5 vendors.
Ask all of them the same questions.
Pick the one that:
• Explains tradeoffs clearly
• Has shipped apps similar to your idea
• Proposes a realistic MVP, not a monster version 1
If you share what your business does and rough app idea, people here can help you sanity check quotes and timelines.
Totally get being overwhelmed, the iOS vendor space is crowded and noisy.
@espritlibre already nailed the basics like scope, pricing models, and contracts, so I’ll skip repeating that and hit a few angles people usually miss:
- Start with who you want to manage long term
Ask yourself:
- Do you want a “set it and forget it” dev shop that does everything, or
- A team that builds v1 and then hands off cleanly so a freelancer or small in house dev can maintain it?
If it is the second, explicitly ask for:
- Clear README and basic technical docs
- Simple architecture, not some overengineered microservices zoo
- A short handoff session recorded on Zoom
Most shops never offer this. Ask early.
- Don’t obsess over which framework, obsess over maintainability
People fight over SwiftUI vs UIKit vs React Native vs Flutter. For a small business, what matters more is:
- Is the codebase understandable to a reasonably good mid level dev later
- Is the tech something you can actually hire for in your region / budget
I slightly disagree with the “only pick teams with 3 shipped apps in React Native / Flutter” thing. For a small and fairly simple app, a strong iOS team that’s newer to SwiftUI can still be fine as long as:
- They show a prototype quickly
- They are honest about learning curve and don’t charge you for their own training time
- Ask “what will you not do in this budget?”
This is my favorite filtering question.
Good teams answer with specifics:
- “We won’t build a full analytics dashboard, just integrate Firebase first.”
- “We won’t do super custom animations until after launch.”
Bad teams say things like “we can do everything” or stay super vague. That “yes to all” posture explodes later as scope creep or surprise invoices.
- Force them to show you their process not just portfolio
Portfolio screens are marketing. Process is reality. Ask:
- How do you communicate week by week
- Do you demo progress every 1 or 2 weeks
- What tool do they use to track tasks (Jira, Trello, whatever)
- Who is your main contact and how fast do they respond
Then ask to see a redacted example of a previous project board or status report. If they cannot show you even a sanitized example, that is a smell.
- Define “done” for v1 like a lawyer
Before you sign anything, write one plain text list:
- v1 is considered complete when:
- App is accepted on the App Store
- User can do A, B, C from start to finish
- Performance: screens load within X seconds on an older iPhone (like XR)
- They fix any “critical” bugs found in the first X days after launch
Have them react to that. Their reaction tells you a lot. Some will try to dodge App Store acceptance responsibility, which is weird for iOS specialists.
- Get a small paid test before committing big money
This is where I differ a bit from the “pick from 3 to 5 quotes and go” approach. I like:
- Pay a small “discovery” / prototype fee to your top 1 or 2 candidates, maybe 500 to 1500
- Ask them to deliver 1 or 2 real screens of your app, clickable, plus a short architecture outline
- Judge quality, speed, and communication on that tiny slice
Yes, it is extra money up front, but it can save you from a 5 figure disaster.
- Ask how they’ll protect your business not just build your app
Specific questions:
- What happens if Apple changes a policy that affects my app
- How will you handle security for customer data, even if it is “just” emails
- How do you avoid being locked into some third party service with high fees
Their answers should show they think beyond just “we’ll code the screens you asked for.”
- Make sure they grok your revenue model
If your app ties into how you make money (bookings, orders, memberships), walk them through your numbers:
- Typical order value
- Expected number of users
- Worst case failure modes (double charges, lost orders, cancellations)
Then ask: “What would you prioritize technically so we don’t lose money here?”
If they stay stuck on colors and animations instead of reliability around those flows, keep looking.
If you share 3 things
- Rough app idea (2 or 3 sentences)
- Country / region
- How much you think you can spend
folks here can sanity check whether quotes and timelines you get are realistic or someone is trying to sell you a yacht when you just need a reliable used car.
