- Use of native language like Java / Swift or hybrid languages like Flutter / React Native
- UX design
- Third party integrations
- Content - Dynamic / Static
- Administrative Controls and Panel
- Payment integration
At the heart of every delivery we keep our core competency of Agile and DevOps so that the time to market is reduced and the cost to future change is reduced. This gives us a major edge, because our speed of delivery due to these practices are 1.5x faster and more quality.
Also, a clear product vision is critical in delivering a project, so we help our clients brainstorm the UX of the application using high fidelity prototypes does in Adobe XD or Sketch, this significantly further reduces development time and rework.
Overall, we have seen that its a 50-50 ratio of Front end and backend work, where we try to use front end power of new age devices for processing information and backend for complex functions / processing. A strong architecture is key to this and hence all our projects have 20% time of an architect built into our proposal.
1. Functional complexity of the application - If it requires native features like AR then Swift / Java is recommended.
2. Technical complexity to support the required functionality
3. Audience targeted through the app
4. Client strategy to generate revenue from the application
5. Funds available to build the app
6. Ease of maintenance and support in future
1. Is there an ongoing relationship with the client?
2. Mobile platform for which app is required (Android / IOS)
3. Is there a need to use native or hybrid stack?
4. Complexity of UX design
5. Is there any third-party integration required?
6. Is the content dynamic or Static?
7. Do we need Administrative Controls?
8. Is there a payment integration required for the application?
9. Do we provide the hosting services or managed servers as well?
10. Duration of the post deployment support required
For ecommerce apps, we recommend simpler 2 step or 3 step pricing plans.
