      Christi Kambs's Review Sourced from Google

      Had such great care here, all of the nurses were kind and friendly, I completely felt safe and listened to by the anesthesiologist and Dr Roost was excellent at explaining my procedure and clearly passionate and skilled in her field. Clearly no none wants to have a colonoscopy but their staff made it as easy and smooth as possible!

      I was pleased with the services I received in the Waverley surgery center for my much procrastinated colonoscopy. Everyone was friendly, caring and attentive which made me feel comfortable and relaxed. Everything went smoothly, they gave clear instructions for after procedure and called next day to make sureeverything was all right. I highly recommend it.

      Holt Group Inc.'s Review Sourced from Google

      Watson has been a key strategic partner for us on the creative and brand side since the beginning. We've worked with various members across the team and every member of their staff brings excellence and authentic passion to what they do. They have consistently delivered an end product that excites our customers, adding special creative touches along the way so that the results really sing. The way they're able to translate our vision and mission into deliverables across each project has been a weight off our shoulders. Not every creative agency is able to understand the nuances of our industry and we've been so impressed with the time team Watson has taken to really get to know our industry in homebuilding. We've worked with Watson on deliverables such as high level creative direction, but also getting into the nitty gritty of developing content around our warranty program. This was a huge task and they matched us with exactly the right team members to bring it to life who truly cared about getting it right. They're great friends as much as they are our business partners. We highly recommend partnering with Watson Creative.

      S Nash's Review Sourced from Google

      When we engaged Watson to help us rebrand, we knew it was going to be a challenging process. We had a long-standing reputation as a respected law firm in Portland, but we wanted our brand to reflect our unique culture and the innovative approach we bring to our clients. Watson's team was thorough and thoughtful throughout the entire process, from primary research interviews with our team to the final custom, hand-drawn identity system. The end result was a brand that not only represents who we are as a firm but also sets us apart from our competitors. We continue to receive compliments on our branding years later, and we credit Watson for helping us achieve that success.

They are accommodating to all requests, efficient, professional and able to build out from core ideas you give them. I would refer them to any other projects within the industry in need of game devs.

      Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!

      I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.

      Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!

iPhone App Development Company Hiring Guide

What is an iPhone app development company?

An iPhone app development company specializes in building high-quality, custom iOS applications for Apple devices, including iPhones, iPads, Apple Watch, and Apple TV. These companies leverage tools and programming languages such as Swift, Objective-C, and Xcode to create seamless native mobile experiences. 

An iPhone app development company can develop the following:  

  • Native iOS apps: Designed exclusively for iOS, offering optimal performance and user experience. Swift enables faster, more efficient development compared to Android. 
  • Hybrid apps: Built to run on multiple platforms, offering broader reach at the cost of native optimization and depth of features.

As Apple's product lineup diversifies, iOS app developers deliver apps for iPhones, iPads, Apple Watch, and Apple TV. 

What do iPhone app development companies do?

iPhone app development companies use the latest technologies to build high-performing, secure iOS applications. They deploy the product in production and submit it to the App Store, ensuring it meets Apple's guidelines and aligns with user preferences for look and feel, ease of use, and performance. 

An iPhone app development company also helps with: 

  • Concept ideation and strategic planning
  • UI/UX design tailored for iOS
  • Native and hybrid app development
  • Backend setup and API integration
  • QA testing and debugging
  • App Store deployment and compliance
  • Ongoing support and maintenance

How much does it cost to develop an app for iOS?

Developing an app for iOS costs $10,000 to over $500,000. On average, businesses spend around $50,000 to launch a reliable iOS app.  

Factors that impact these costs are: 

  • App's level of complexity 
  • Backend configuration and administration 
  • The company's experience and team size 
  • Time needed to develop the app from scratch 

The following table breaks the total cost estimates down based on complexity and timeframe:

App complexity Cost Timeframe 
Simple app $10,000 to $60,000 2 to 4 months 
Medium-complexity app $60,000 to $100,000 4 to 6 months 
Complex app $100,000 to $500,000+ 9+ months 

[Source: SPD Load]

iPhone app development companies typically charge on an hourly basis. They calculate development costs by multiplying the number of hours required to develop each feature by the hourly rate for the development team. 

Here are the average hourly rates for the individual roles in an iPhone developer team:

RoleAverage hourly rate 
iOS app developer $50 to $100 
UI/UX designer $20 to $50 
Project manager $50 to $150 
QA engineer $30 to $80 

[Source: InfoStride

How long does it take to make an iPhone app?

Building an iPhone app can take three to nine months, depending on its complexity and features. For a clearer perspective, here are estimated timeframes for iOS app development:

 Simple apps Medium-complexity apps Complex apps 
Requirement analysis and planning 1-2 weeks 2-3 weeks 3-4 weeks 
Wireframing 1-2 weeks 2-3 weeks 3-5 weeks 
UI/UX design 2-3 weeks 5-6 weeks 9-10 weeks 
Development 6-7 weeks 14-15 weeks 20-22 weeks 
QA and deployment 1 week 2 weeks 3 weeks 
Total 11-15 weeks / 2-4 months 25-29 weeks / 5-7 months 32-44 weeks / 7-10 months 

Why should I hire trustworthy iOS app developers?

These are the top three reasons to hire an iPhone app development company: 

1. Keep sensitive data secure 

Partnering with a professional iPhone app development company will ensure the highest level of security for your app and keep your data safe from external threats. 

2. Enhance customer experience 

iOS app developers can help increase user engagement and retention by: 

  • Using push notifications properly
  • Running retargeted advertisements
  • Sending in-app personalized messages
  • Leveraging machine learning (ML) for recommendations

3. Generate higher app revenue 

iPhone applications drive a high return on investment (ROI) from in-app purchases, subscriptions, and premium games. Professional iOS development leverages the latest trends and technologies to deliver the best user experience. 

Success story

Fullestop developed a multilingual iOS app featuring real-time tracking, secure payments, and an intuitive UI.  It also developed the app in English and Arabic to eliminate language barriers. The app scaled to 5,000+ orders post-launch and projected 30,000+ in its first month.

How do I hire a trusted iPhone app developer?

Follow these steps when hiring a reliable iPhone app developer: 

  1. Define your requirements and assess your budget. This is also where you decide on whether you need a native or a hybrid application. 
  2. Research and compare the top iOS app development companies.
  3. Read and verify client reviews, ratings, and recommendations. You can also ask your network about the companies you've researched. 
  4. Look at their portfolios and check for projects within your domain. Evaluate the stages of their design process: wireframing, concepts, storyboards, prototyping, and others. 
  5. Ask about their approach to UI/UX design. Examine their development process, methodologies, tools, iOS software development kit (SDK), and proficiency in Swift and Objective-C programming languages, frameworks, and databases. 
  6. Check whether they provide a full cycle of iOS app development services, including research and market analysis, API development and integration, testing, and post-release support and maintenance. 
  7. Select up to five candidates from your list. Send them a request for proposal (RFP) and ask for price estimates with a breakdown. 
  8. Receive and review proposals. Arrange interviews to get to know the teams that developed the proposals. 
  9. Decide based on your evaluations, and examine the contract before entering into an agreement.
