NeptuneAI is a solo-founder studio building native mobile tools that do one job well — starting with Compressor: Image & PDF, a Kotlin + Jetpack Compose app for Android, with iOS in the works.
Most utility apps try to do everything and end up doing nothing particularly well. NeptuneAI takes the opposite bet: pick one real, everyday problem, build a native app that solves it properly, and keep shipping fixes and polish long after launch.
That means real device testing, not just an emulator; engines built on libraries chosen for correctness over convenience; and a build log that tracks every decision — including the ones that got reverted.
Kotlin and Jetpack Compose, not a cross-platform shim — direct access to the APIs that actually matter for CPU-heavy work like compression.
Every feature verified end-to-end on physical phones and tablets, not just assumed to work from the emulator.
Ad-supported, clearly labeled, gated behind a consent flow — no dark patterns, no forced subscriptions for basic function.
A native Android app that shrinks images and PDFs without wrecking quality — built for the everyday moment when a file is just too big to send.
Compress single files inline or queue a whole batch in the background — image resizing, cropping, and target-file-size search for both photos and PDFs, two PDF compression modes (recompress embedded images, or rasterize aggressively), merge with reorderable pages, split, and image↔PDF conversion. The interface is available in six languages.
Native Kotlin builds, Material 3 design, tested across phone, tablet, ChromeOS, and Android XR form factors. Compressor: Image & PDF is the first release.
A native iOS build of the same idea is on the roadmap — no shim, no wrapper, same standard of on-device testing before it ships.
NeptuneAI started as one developer's answer to a small, annoying problem — files that are always slightly too big. Every screen, every edge case, every crash fix in Compressor: Image & PDF has been built and tested by hand, on real devices, before it ships.
