Mobile App Development for Home Bakers' Unit
"They are the most responsive service provider."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
I am the director of a home bakers unit which based home based. We get hundreds of order every day from different locations nearby.
For what projects/services did your company hire AppSierra?
We receive hundreds of orders from different parts of our locality on daily basis and for the smooth ordering we managed to build a mobile app. But it was too basic version and it had a lot of issues including user interface . So we connected with Appsierra to rebuilt the mobile app and to give it a new look and better performance. The main reason for the quick rework was the huge raise of orders that we received during the covid 19.
What were your goals for this project?
We wanted to resolve the customer complaints regarding the slow pace of the working of our old version mobile app. As because of the covid 19 we experience a huge spike in the order the app almost stopped working and this made us really struggle to work during the pandemic. So we wanted to built a quality, user friendly application that will enable our customer to order products through our app smoothly.
How did you select AppSierra?
We found out about Appsierra via a peer recommendation and had a meeting to decide how to move forward. They recommended the needed changes and the strategies.
Describe the project in detail.
They recommended going with a simple and easy-to-use interface as it will help in improving user experience and downloads. Instead of doing this that we told, they were giving us feedback and advice. The team developed mobile apps for iOS and Android using native languages . The platform has new features such as a real-time chat tool, saved search with alerts, social logins, and highlighting products according to the tastes to the user. The team conducted end-to-end development. We provided our specifications and old data bases before starting the rework. We then offered feedback and testing throughout the project.
What was the team composition?
They provided us with three to four people, including a tech lead and project manager and developers. The team had excellent skills and they worked well as expected..
Can you share any outcomes from the project that demonstrate progress or success?
The end product made the quality at high and prevented bugs and issues that the platform experienced. They completely rewrote the previous architecture of the app. The clearest impact of the success of the project was seen in the speed/response time of the app which we had the concerns. Soon after the relaunch we seen a huge spike in the downloads and despite of the huge numbers of downloads and users, the app is preforming well.
How effective was the workflow between your team and theirs?
In my opinion, they are the most responsive service provider. When i compare the company who built the old app with Appsierra, i can clearly see the difference and impact. Appsierra managed the project very well and they coordinated very well with me and took more responsibility than me. We had daily meetings and received weekly activity reports. Even their feedback times were super fast.
What did you find most impressive about this company?
Appsierra provided us a project manager who did a wonderful job. They shown both professional as well as personal quality. I was concerned about the communication between a team with whom i never met, but they were just superb. Appsierra stood up to my expectations as a committed company, with professional quality and ethics, and dedicated friendly team.
Are there any areas for improvement?
Nothing to report regarding this matter. They are very much professional and no room for complaints.

WordPress Dev & SEO for Website Network
"As a partner, AppSierra is completely self-motivated."
the reviewer
the review
The client submitted this review online.
Please describe your company and your position there.
I own a web design and development company. I act as project coordinator and developer for clients.
For what projects/services did your company hire AppSierra Solutions?
My client wanted to develop WordPress websites with layouts and plugins, complex additional backend features, and user functionality. The solution also needed to allow future app development for accompanying products.
What were your goals for this project?
We needed to develop an online system that would serve our contractors and generate leads as well as SEO and marketing opportunities. By using a popular open-source platform, we wanted to ensure flexibility and a supportive foundation.
How did you select this vendor?
We've worked with several development companies from the U.S. and India that we found on Guru, Upwork, and similar platforms. Generally, we tested them on smaller projects first before starting a long working relationship. AppSierra was the only provider that maintained a professional approach, met the deadlines, and exceeded our goals. In fact, most other companies abandoned projects in the middle of development because they lacked the right skill set, never finished the contracted work, charged higher prices that they originally quoted, didn’t meet our specifications, or even lied to us after missing deadlines by months.
Describe the project in detail.
Because we have an existing confidentiality agreement, I can’t provide specifics. In short, AppSierra took over a single website project that was late by a full year and didn’t meet our specifications. They redid the whole site and improved it. Due to our experience with AppSierra, we're now working on a large network of sites as well as apps and SEO.
The company owner for whom I'm managing this project requested a full-time developer and three to four weekly Skype meetings. During each meeting, the owner supervises the work, and we go through additional brainstorming and goal changes. AppSierra has been incredibly flexible, providing us with structure despite the huge time difference and the additional difficulties this style of work creates. The company owner has the final word on all design and functionality decisions and participates in our Skype meetings. I’m acting as the U.S. project manager, as well as the additional developer, troubleshooter, designer, and mediator between tech people and the client.
AppSierra provides resources as needed based on each task’s scope. One developer is assigned to our project exclusively. An AppSierra manager also provides regular quality control and sorts out the logistics.
What was the team composition?
AppSierra structured the project using Jira. We provided documentation and continuous feedback. The client's side consisted of a single person with executive decision-making capabilities, two assistants, and myself as the project manager. AppSierra assigned several people to different projects based on their skill sets and provided the primary project coordinator to ensure all of our needs were met and the right people were working on each task.
What outcomes or results can you share that demonstrate progress and/or success?
AppSierra's suggestions and solutions were often more creative, efficient, and aesthetically pleasing than we expected. We're still happily working with them exclusively and are confident in their skills to move on to larger projects together.
How effective was the project management?
They met our deadlines and were accessible through Jira and Skype. The language difference was not a problem, although we occasionally had call-quality issues while using Skype.
What did you find most impressive about this company?
They're organized, have a wide skill set, and guide clients in a way that promotes results. At the same time, they’re flexible enough to accommodate our idiosyncrasies. They delivered solid work and met our deadlines consistently. Ultimately, they distinguished themselves from the other vendors we’ve worked with through their professional conduct and reasonable prices.
What tips or recommendations do you have?
As a partner, AppSierra is completely self-motivated. If you have absolutely no technical knowledge, I’d recommend finding a member of your company with some experience and asking this person to communicate with AppSierra. AppSierra wants to understand the client’s goals and expects informed and detailed answers. I think they’re a great match for a startup or a larger company that already has a tech team but needs to expand their capabilities.

The client submitted this review online.
Please describe your company and your position there.
I'm the product manager of a web app connected, data driven smart locker company for businesses.
For what projects/services did your company hire AppSierra , and what were your goals?
I'm the product manager at a leading smart locker company and we hired AppSierra to test both our app. The goal is to also getting them to test our hardware as well for a full end to end test.
How did you select this vendor and what were the deciding factors?
When we were looking at all the applicants for the position AppSierra really stood out as very professional and went quite in-depth with their feedback to the tasks we assigned to them, well above any of the other competition.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
We had a kickoff meeting to discuss our needs and requirements and AppSierra came back with an in-depth document on their strategy they were going to implement via manual testing of both of our main web apps. The next step for AppSierra is to do automated testing which they said they would happily provide, it's really great how they have a solution to any problems we might have testing wise.
How many people from the vendor's team worked with you, and what were their positions?
I believe we've worked with two of their manual testers, one being replaced by the second when they were no longer available, the transition was flawless between these two and we did not need to provide further training as they did it themselves.
Can you share any measurable outcomes of the project or general feedback about the deliverables?
After using AppSierra we found out we had a lot more bugs that first thought and they worked very thoroughly when assigned tasks to test.
Describe their project management style, including communication tools and timeliness.
Sprint, agile, using click-up.
What did you find most impressive or unique about this company?
They are very helpful to your needs and accommodate very well.
Are there any areas for improvement or something they could have done differently?
Nope, they were super!

For what projects/services did your company hire AppSierra?
We acquired an app and began refactoring, encountering numerous bugs. To free up local resources we began outsourcing services like app development and especially QA testing. We needed a fluent English speaker who was technical and knowledgeable with manual and automated testing to check nightly builds and have feedback ready for our team in Toronto the following day

We found AppSierra through Upwork, and following a successful pilot program there we have been working on an ongoing basis since. They were also able to fill in with some graphic design work as needed through a separate contractor
Describe the project in detail and walk through the stages of the project.
Without going too specific, I can say it is an app adored by esports gamers worldwide. As we added new features and games, by integrating various APIs, we frequently encountered unpredictable results. So we required a person to download nightly builds and go through the app with fresh eyes every time and try to break things, and articulate the problems in such a way that it was repeatable and easy to understand for the app team.
How many resources from the vendor's team worked with you, and what were their positions?
This is a focused group project - We're a small team of ten, mostly developers. Our company however has over 500 employees
Can you share any outcomes from the project that demonstrate progress or success?
Overall we're very happy with the quality and industriousness of the contractor, who is very consistent and communicative. Relative to local costs, we have saved money.
How effective was the workflow between your team and theirs?
Over time the app has improved in direct results of their QA work, so I would say this process is effective
What did you find most impressive or unique about this company?
They are knowledgeable, detail-oriented, and communicative. It's also nice that they can provide a range of other IT services on a whim, and on short notice. It is a collective of talented people
