FAQ
Frequently asked questions
Answers to questions we hear most often
What services does BTG offer?
We provide end-to-end VPN application development for iOS and Android, social media marketing and advertising, UI/UX design, and server infrastructure management. We can handle a single service or the full product lifecycle.
How long does it take to develop a VPN app?
A typical MVP takes 4–6 weeks from kickoff to App Store submission. A full-featured product with multiple protocols, custom UI, and server infrastructure usually takes 8–12 weeks.
Which VPN protocols do you support?
We build apps with VLESS, WireGuard, OpenVPN, and Shadowsocks. We can also integrate custom protocols or hybrid setups based on your product requirements.
Do you provide support after launch?
Yes. Every package includes a post-launch support period. For long-term engagements we offer 24/7 infrastructure monitoring, feature development, and SLA-backed priority support.
How does the SMM process work?
We start with an audit and strategy, then move to content production, targeted advertising, and monthly reporting. You'll get a clear roadmap and measurable KPIs from day one.
