RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Through our partnership with Semaphore Mobile, NspectAI has evolved from a concept into a fully operational, AI-powered home inspection platform now available on the Apple App Store and Google Play Store. Key measurable outcomes include:As a newly launched platform, our early success metrics are primarily focused on product development, validation, and market readiness rather than long-term adoption data. As adoption grows, we’ll track additional performance metrics, including active users, inspections completed, report generation times, subscription conversion rates, customer retention, and user satisfaction scores. Early indicators suggest strong interest from inspectors seeking to leverage AI to improve efficiency without sacrificing reporting quality.
Semaphore Mobile helped transform my vision for NspectAI from an idea into a fully operational software platform. Their team provided the technical expertise needed to develop the mobile application, integrate AI capabilities, and build the backend systems that power the platform. Through our partnership, NspectAI evolved into a real-world solution for home inspectors and is now available on both the Apple App Store and Google Play Store.

Their team maintains clear communication, provides regular updates, and remains receptive to feedback as the platform evolves. As new ideas emerge and real-world testing provides additional insights, Semaphore Mobile works closely with us to refine features, improve workflows, and enhance the overall user experience.
What did you find most impressive about them?
What impresses me most about Semaphore Mobile is their willingness to truly understand the home inspection industry rather than simply build software from a specification document. From the beginning, they took the time to learn our workflows, challenges, and goals. They listened to feedback from real inspectors, asked thoughtful questions, and worked collaboratively to refine the platform throughout development.
Are there any areas they could improve?
Overall, Semaphore Mobile meets my objectives and successfully helps bring NspectAI from concept to a fully launched product. As with any complex software development project, there are always opportunities for refinement and enhancement, but I view those as part of the normal development process rather than shortcomings. The team remains responsive, collaborative, and committed to finding solutions whenever challenges arise.

BACKGROUND
Please describe your company and your position there.
I am a Community Health Worker (CHW) and the Program Coordinator at a public health agency located in Paris, Texas.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Semaphore Mobile, and what were your goals?
We wanted to develop a mobile app that highlighted and promoted locations and available activites along a local trail named Trail de Paris. We are a local health dept want to encourage health lifestyles within our community, as well as for visitors to our city. Our goal was to have a user friendly app that showed features along the trail or local sites worth visiting or exploring.
SOLUTION
How did you select this vendor and what were the deciding factors?
We searched online for developers in our area. We are a small town, so I had to search the Dallas TX area which is approximately 125 miles away. We narrowed it down to two different app developers. We ended up choosing Semaphore Mobile due to their professionalism, friendliness, and previous experience with developing mobile apps.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
We had several meetings discussing needs & wants of the project. I knew nothing about signing up thru apple and google for web development, but they sent me specific instructions on how to get this signed up and assign access to their team members. They communicated with me frequently to keep me up to date on progress as well as to notify me of what they needed from me.
How many resources from the vendor's team worked with you, and what were their positions?
There were about three people that worked closely with me on the project. They were all extremely helpful!
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
They were able to finish the app in time for us to be able to share it with the community on a day celebrating 50 miles of the trail. Our local Chamber of Commerce also wants to share the Active Paris App promotion cards in 2000 new resident welcome packages that will be created at the end of July.
Describe their project management style, including communication tools and timeliness.
The company was very easy to communicate with and very helpful. I am not very tech savvy, however, they were always quick to help.
I developed a very bad case of COVID right after we were starting the project. I was out of the office for 5 weeks straight and I know I caused many delays in the process by not being able to get them the pictures and info they needed. They were EXTREMELY KIND AND PATIENT with me and my circumstances and even demonstrated a true concern for my health. I will not forget the kindness they showed me during this time. They were very responsive and timely throughout the project and were very effective communicators.
What did you find most impressive or unique about this company?
They were very professional, friendly, and helpful. They were also extremely patient with me while I battled COVID and delayed their progress. I don't know that other companies would have been so kind and understanding. They did an amazing job on the app, and we are pleased with the results. It was exactly what we envisioned and more.
Are there any areas for improvement or something they could have done differently?
I was extremely pleased with this company and will not hesitate to hire them again for future projects.

transcript.
BACKGROUND
Introduce your business and what you do there.
I’m the app development director at the Angel Homes Funeral Investment Group.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Semaphore Mobile?
We hired Semaphore to build our app.
SOLUTION
What was the scope of their involvement?
Semaphore built our app from scratch for both Android and iOS devices. I didn’t provide any pre-built code, but I gave them references in the form of other apps that were similar to what we wanted.
In terms of features and functionality, we wanted the app to allow users to send text messages to multiple people at the push of a button. It also had GPS functionality. The team also designed our website and logo.
At present, the app and website aren’t live yet, but we’ll be launching them soon.
What is the team composition?
I work with Eric (Owner) and his two sons, one of which is in sales while the other helps in coding the app.
How did you come to work with Semaphore Mobile?
I was looking for app development companies that were knowledgeable and willing to have a conversation with us without rushing into financial matters. We wanted a team that was genuinely interested in the project. That was important to me; I needed someone who was passionate and cared about what they were doing for the customer. These were the reasons we hired Semaphore.
How much have you invested with them?
Our company has invested around $100,000 in the project.
What is the status of this engagement?
We started working together in September 2021, and the engagement is ongoing.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
We’ve beta tested the app, and we’ve received no complaints in terms of the functionality and design of the app. It has good quality. Of course, we’ve found bugs, but that’s the purpose of beta testing. As far as appearance and functionality go, Semaphore has delivered 100% of what we want.
How did Semaphore Mobile perform from a project management standpoint?
Their project management is great. The team has been thorough with their work. Their resources reach out to us and give updates on time, and they’re forward-thinking. If we have any questions or concerns, they’re always available to answer and handle everything. To communicate, we use emails, phone calls, and in-person meetings.
What did you find most impressive about them?
Semaphore has the ability to build rapport with their customers. They’re not quick to dive into our pockets. Instead, they’re genuinely interested in our ideas and concepts as they build and maintain the relationship. This quality of theirs is unmatched, and other companies can learn from them.
Are there any areas they could improve?
No, there aren’t any.
Do you have any advice for potential customers?
When presenting your idea to Semaphore, it’s best to have a detailed outline of what you want. Give them as much information as possible. This will help the team’s understanding of the project and the communication flow will feel a bit smoother.

BACKGROUND
Introduce your business and what you do there.
I’m the founder and CEO of a creative agency that does branding, website development, and video production.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Semaphore Mobile?
We had a client who was looking to build a mobile app. Although we had a lot of design experience, mobile development wasn’t our expertise. We needed someone to execute our design.
SOLUTION
What was the scope of their involvement?
First, we discussed the project with Semaphore. From there, they took the lead in developing the app.
What is the team composition?
We worked with Eric (Owner), Renee (Project Manager), a lead developer, and a developer.
How did you come to work with Semaphore Mobile?
Semaphore Mobile was referred to me. The first conversation I had with Eric was really positive — he answered all my questions, and he was very kind. His team had shown a genuine interest in working with us, so hiring them for this project was a no-brainer.
How much have you invested with them?
We spent $20,000.
What is the status of this engagement?
We worked together from April–December 2021.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
Semaphore did everything I asked them to do and exceeded all our expectations. They took the design we created and brought it to life, overcoming the challenges along the way. The end product was outstanding — our end client was pleased with their work.
How did Semaphore Mobile perform from a project management standpoint?
Semaphore’s communication was top-notch. I never had to question where we were as they were always on top of the project.
We experienced a lot of delays from the end customer, but Sempaphore worked efficiently. They had excellent communication skills, and they checked in with us almost daily. They streamlined the project and helped us get across the finish line.
Semaphore’s team was kind and understanding whenever we had delays. Overall, they were great at project management.
What did you find most impressive about them?
Semaphore did a good job communicating and ensuring the project’s progress. In addition, their team is very personable — they seem to care both about the project and me as a person.
Are there any areas they could improve?
I can’t think of anything.
Do you have any advice for potential customers?
Get your ducks in a row — once Semaphore gets the job, they’re ready to hit the ground running. Ensure your project is ready and things are organized so that you can make some quick movement.

Semaphore Mobile migrated the Android mobile application for a wastewater disposal company. They worked with another IT company to integrate the app with the website and fixed bugs from the previous developer.
In less than two months, Semaphore Mobile successfully completed the development work. They stood out for their flexibility and ability to cooperate with the client and another vendor. The team was responsive and well-organized; they kept constant communication through Zoom, emails, and phone calls.

client over the phone. Below is an edited
transcript.
BACKGROUND
Introduce your business and what you do there.
I work for East Texas Salt Water Disposal. We handle wastewater from the oil production extraction process, and the company is based in Kilgore, Texas. I’m a GIS data analyst; I handle the maps and process water leaks data or anything related.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with Semaphore Mobile?
We had a complicated website that matched up with a mobile application. We were working with another company, but we were having a hard time getting responses from them. They also charged ridiculously high rates, so we just wanted to find someone else to work with.
SOLUTION
What was the scope of their involvement?
Semaphore migrated the Android mobile application that our operators use to record data. We provided the data and existing React codebase from the previous provider, and they handled the rest on their own. They didn’t remake the app, so they researched a bit to figure out what the other company had done.
Since the app and the website communicate back and forth in a complicated setup, we had our IT company as a web developer, and Semaphore worked with them for the mobile app development. They handled a couple of design aspects, but they fixed bugs for the most part.
Now, we’re keeping them on retainer to provide security updates and timely support if the app goes down.
What is the team composition?
We only had to deal with one person. We occasionally talked to the president, but we mostly worked with the senior developer. They also had a couple of people in India, and they delegated the work to them and coordinated from there.
How did you come to work with Semaphore Mobile?
We tried to look for local companies first. There were 1–2 candidates, but they had $10,000 minimums or wanted to remake the entire app. We searched on Google and picked Semaphore because they were within driving distance. If everything caught on fire, we could be at their office within a day.
Also, their president reached out to me personally at the beginning of the project, during, and after it was finished.
How much have you invested with them?
We spent a little over $7,000, and they’ve agreed to charge us $75 an hour for any maintenance moving forward.
What is the status of this engagement?
We started working together in July 2021, and it was a month and a half to get what we needed. Now, we have an ongoing maintenance contract.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
When there were problems during development, they immediately responded. They worked with a company that they’d never dealt with before, and they immediately started integrating the mobile app with them. Additionally, their turnaround was short. It was all outstanding.
Overall, we were glad we found them. It was easy to get things off the ground and get moving with Semaphore.
How did Semaphore Mobile perform from a project management standpoint?
They did a fantastic job. Their president would reach out to us once a week to check and see how things were going, and the lead developer talked to us once every couple of days.
When something minor went wrong, we’d email them and get a response in about 30 minutes. Otherwise, we had Zoom calls for serious matters, and sometimes the president would call to my cellphone.
What did you find most impressive about them?
It was their flexibility. They took what they were given and billed us hourly no matter what it was for.
Are there any areas they could improve?
I can’t say what they could’ve done differently.
Do you have any advice for potential customers?
Have a good idea of what you want the application to do, who is meant to use it, and how.
