Custom app development for the way you work.
Plopjoy handles custom app development for businesses that need software no one sells off the shelf. We build web apps, client portals, booking systems and internal tools — with AI features built in or bolted on.

Custom app development without the agency bloat
Sometimes the tool you need simply does not exist. Or it exists, but it costs a fortune and does half of what you want.
Our custom app development starts small and ships fast. First, we scope the workflow and the must-have features. Then we design, build and test in short cycles, so you see progress every week. Finally, we launch, train your team and keep improving it.
We build booking systems, client portals, inventory tools, quoting apps and AI assistants. So if you can describe the job, we can build the tool.
Security matters. We build against the OWASP Top 10 risks from day one. See our software and platform work in the portfolio.

FAQ
Custom app development FAQs
Do you build mobile apps?
We focus on web apps that work beautifully on phones, tablets and desktops. Native app needs are scoped case by case.
How much does custom app development cost?
It depends on features and integrations. We scope a fixed first version so you know the price before we start.
Who owns the code?
You do. When the project is paid, the app and its code are yours.
Can you add AI to my app?
Yes. We add AI assistants, document summaries, lead scoring and other automations where they save time.
Is the app secure?
Yes. Every app we build follows proven security practices like the OWASP Top 10, with roles and permissions from day one.
