Appreciation from Clients

I would like to thank the entire Space-O team for helping us with our photo editing app. We have been working with other developing teams before, and we were able to find Space-O. And all the other developers failed to deliver all great working apps for us. Space-O helped to design the app in a very user-friendly way. They helped us to navigate solutions for the app. And overall went above and beyond with our request.

I hired them for a BA assignment for a project. They did a fantastic job. Quite professional and also good at making the customer understand non technical aspects. Put their mind to think like the customer. A guy named Jaimin was assigned as the work lead and really appreciate his knowledge, understanding customer perspective on the assignment and come up with very valid suggestions. Recommended for mobile app development.

Riccardo Petrachi

We searched online for app developers that had an extensive experience in mobile app development as well as a strong presence in the market. We chose Space-O specifically because of the up-close experience we had with another app they had developed and we wanted to achieve the same high level of standards, quality, and satisfaction. We were looking for brilliant experts and we found them.
Frequently Asked Questions
How long does it take to develop a cross-platform mobile app?
Generally, simple cross-platform development takes around 2-3 months. Enterprise cross-platform mobile apps with advanced features require about 3-6+ months. However, cross-platform mobile app development projects vary based on the complexity of the app, multiple operating systems, the features required, and other client-specific needs.
How much does it cost to develop a cross-platform mobile app?
Generally, cross-platform development starts from $20000. Developing cross-platform mobile applications depends on the complexity, location, and technology stack used in the app. We offer various pricing models to suit different project needs. This could be a fixed price for well-defined projects and an hourly rate for more flexible or evolving projects. All pricing details are transparently discussed and agreed upon before the commencement of your cross-platform development.
Do you sign an NDA?
Yes, we sign a non-disclosure agreement (NDA) to protect your intellectual property and the confidentiality of your cross-platform app information throughout the mobile app development process. This helps to avoid third-party discrepancies if they occur during your cross-platform app development.
How do you handle data security?
Data security is a top priority for us. We implement industry-standard security protocols, including encryption and secure data storage. Our cross-platform development practices are designed to comply with data protection regulations like GDPR or HIPAA, depending on your industry.
Will I be involved in the project throughout the mobile app development?
Yes, your involvement matters to us at every stage of the project. Since we use Agile mobile app development methodology, we take your regular updates, and reviews, and conduct feedback sessions to ensure that your cross-platform app meets your expectations. You will be assigned a dedicated project manager who keeps you updated on the project’s progress. Communication channels like email (Gmail), video conferencing (Zoom, Skype), and project management tools(Basecamp, Jira) are used to keep you in the loop.
What are the payment terms and conditions?
Payments are generally milestone-based, tied to specific deliverables throughout the project. An initial deposit is usually required to kickstart the project. Terms for termination, refunds, or adjustments are clearly outlined in our contract to protect both parties.
