Small Android apps
that do one job well.
Zenvoq Labs is an independent studio. We design and build focused Android apps — our own, like FramePDF, and for founders who want one built.
The stack we ship on
Built and shipped by us
Our own product on Google Play — and the free web tools we built around it.
FramePDF
Pull pictures, tables and questions out of a PDF, save pages as photos, rearrange pages, and export to Word, images or a ZIP. Everything runs on the phone — no account, no upload.
Alongside it, we built free browser tools and exam upload guides that process files on-device too.
More in progress
We have more Android apps in the works. Have one in mind you'd like built?
From idea to Play Store listing
Pick a slice or hand us the whole thing. We work the same way on client apps as on our own.
Product build
A complete Android app in React Native and Expo — designed, built and ready for the Play Store.
MVP to launch
Scope the smallest version worth shipping, build it, and get it in front of real users.
On-device features
Work that runs on the phone instead of a server — PDF processing, image handling, offline-first storage.
Web & search
A Next.js site that brings people to your app — landing pages, free web tools and search-friendly guides, like the ones on this site.
Take over an app
Picking up an existing React Native or Expo codebase: get it building, understand it, and plan what to fix first.
Store & compliance
Play Console setup, privacy policy and data-safety form, so publishing goes smoothly.
The questions founders ask first
Still unsure about something? Reach out — we answer in plain terms.
