Frequently Asked Questions
Everything you need to know about our engineering standards, pricing transparency, sprint cycles, and IP ownership.
What is your pricing model and how do you estimate project costs?
We offer both fixed-price milestone contracts and dedicated monthly hourly teams. Every proposal begins with a complimentary scoping session where we break down features, architecture, and complexity into a transparent line-item estimate so you know exactly what is delivered.
How long does it take to develop and launch an MVP mobile app?
Simple to medium MVPs typically take 6 to 10 weeks from initial Figma wireframing to App Store and Google Play deployment. Complex ecosystems with custom hardware/BLE or heavy AI integrations typically require 3 to 5 months across agile 2-week sprints.
Do you sign Non-Disclosure Agreements (NDAs) before discussion?
Yes, unconditionally. We execute a mutual Non-Disclosure Agreement (NDA) before diving into any confidential concepts or technical documentation to legally protect your intellectual property from day one.
Who owns the code, design assets, and intellectual property?
You own 100% of the intellectual property. Upon project completion and milestone handover, complete git repositories, Figma design systems, backend configurations, and store listings belong exclusively to your company.
Why do you recommend Flutter over other cross-platform options?
Flutter compiles directly to native ARM machine code without slow JavaScript runtime bridges (unlike React Native). It delivers identical 60fps rendering across iOS and Android from a single codebase, accelerating feature velocity while saving up to 40% in maintenance costs.
Do you assist with Apple App Store & Google Play submissions?
Yes. We manage the entire store release lifecycle including developer account provisioning, App Privacy questionnaires, screenshot sets, compliance checks, and expedited review handling.
What communication and project management tools do you use?
We integrate directly into your workflow with dedicated Slack/Discord channels, Jira/Linear sprint boards, weekly live demo calls, and automated TestFlight / Google Play internal test distribution.
What post-launch maintenance and support options are available?
We provide dedicated post-launch SLA maintenance covering continuous OS compatibility updates (iOS & Android releases), performance monitoring via Sentry, bug triage, and feature expansions.
