Zero tracking
We omit analytics, ad SDKs and fingerprinting.
Kotlin + Compose, handcrafted in‑house
At evopiep.com we deliver offline‑first Android apps, free of trackers and advertising IDs, every time.
In practice
Prism Path follows the same rules: native Android, fast launch, no data leaves the device.
Four rules we never bend.
We omit analytics, ad SDKs and fingerprinting.
All data stays on the phone.
We treat background work as a cost and measure it.
Screens work with TalkBack, large text and proper contrast.
From sketch to release, we handle every Android detail with care.
Kotlin from day one. Apps run smoothly on modest hardware.
Declarative UI, Material 3, adaptive layouts and fluid motion.
Room and DataStore keep everything on‑device, even in a tunnel.
We profile start‑up, jank and background work, then monitor Android Vitals.
TalkBack labels, contrast and large‑text support are integral, not an afterthought.
Signed builds, staged rollouts and steady updates as Android evolves.
Four clear stages, each delivering a tangible result.
Define the problem, users and absolute no‑go rules.
Sketch screens, data flow and permissions before any code.
Write Kotlin, Compose UI and tests; ship small builds to try.
Stage rollout on Google Play, then monitor, fix and update.
One-way data flow: the interface observes state, and the repository owns the data.
Common queries answered.
We design, build and maintain Android apps with offline use and privacy as defaults.
