Mobile apps built to a standard you can feel.
Native iOS and Android, engineered for the details most teams skip: performance, motion, offline, and finish. After the success of NostalgicPod, its creator Jesus Curreri joins ataraxy as Mobile Advisor to lead our mobile development. Built under your brand and transferred to your team, so you own every line.
Most apps ship. Few of them feel built.
The distance between an app people tolerate and one they love is craft. And craft is a choice.
Most mobile work stops at functional. Lists that stutter, default transitions, no story for when the network drops, and touch that feels a half-second behind. It passes review, ships to the store, and quietly gets deleted a week later.
The apps people keep are the ones where someone sweated the details - the physics of a scroll, the weight of a tap, the moment before a screen loads. That work rarely shows up in a spec. It shows up in the product. It is the difference we build for.
NostalgicPod: what craft looks like in your pocket.
The app that turns any phone into an iPod. Designed, engineered, and shipped solo by Jesus Curreri, who joins ataraxy as Mobile Advisor to lead our mobile development.
NostalgicPod rebuilds the iPod from scratch for modern phones: lossless local playback, a click wheel that actually feels real, and zero cloud. It shipped on Google Play and iOS, earned 4.8 stars, and drew coverage from Android Police, Product Hunt, Android Authority, and Android Planet. One engineer. Every detail deliberate. That success is what brought Jesus to ataraxy, and it is the benchmark our mobile practice now builds to.
Lossless, not lossy
FLAC playback up to 24-bit / 192kHz on a Media3 / ExoPlayer pipeline, with Dolby Atmos and spatial audio where the device supports it. Built for people who can hear the difference.
A click wheel that feels real
A physics-driven virtual wheel with 30ms haptic clicks tuned by hand, snap selection instead of laggy sliding, and transitions matched to the original iPod firmware easing curves.
Zero backend, zero tracking
No servers, no login, no analytics. Everything runs on the device, offline, with a single-file backup you control. Privacy by architecture, not by policy page.
More than a player
Full podcast and internet-radio support, self-hosted server sync for Jellyfin, Navidrome and Subsonic, and three built-in retro games with real haptics. A complete product, not a demo.
After NostalgicPod, Jesus leads mobile at ataraxy.
Following the success of his own app, Jesus Curreri joins ataraxy as Mobile Advisor to lead our mobile development. You work directly with him and the ataraxy founders - no account managers, no junior bench, no offshore handoff.
Jesus Curreri
Creator of NostalgicPod, the iPod-inspired music player he designed, engineered, and shipped solo on iOS and Android: lossless hi-res audio, hand-tuned haptics, motion matched frame by frame, and an architecture with no backend to leak or break. Featured by Android Police, Product Hunt, Android Authority, and Android Planet, 4.8 stars on Google Play.
After that success, Jesus joins ataraxy as Mobile Advisor to lead our mobile development. He sets the bar for every build and leads the work hands-on.

LinkedIn →From one screen to the whole app.
Native where it counts, pragmatic where it doesn't. We build the app, launch it, and hand it over.
Native iOS
Swift and SwiftUI apps that feel like they belong on the platform - fluid, accessible, and tuned to Apple's latest.
Native Android
Kotlin and Jetpack Compose, engineered for the real spread of devices your users actually carry, not just the flagship.
Cross-platform when it fits
When speed to both stores matters more than platform-specific depth, we ship a single codebase that still feels native. We tell you honestly which path fits.
Offline-first & real-time
Local-first data, background sync, media and audio pipelines, and real-time features that hold up when the connection doesn't.
Performance & motion
60fps lists, considered haptics, and motion designed frame by frame. The finish that makes an app feel expensive.
Store launch & beyond
App Store and Google Play, from submission and review to release, staged rollouts, and the updates after. In your accounts, in your name.
Built under your brand, owned by you.
The ataraxy way, applied to mobile. We embed, we build, and we hand you the keys.
Scope
We get inside the product, agree on one clear outcome, and lock a fixed scope and price. No open-ended retainer, no surprise change orders.
Build
Native code in your repositories, tested on real devices, shown to you in working builds every week. Jesus leads the work hands-on, not from a slide deck.
Ship & transfer
The app goes live in the stores under your brand, in your accounts, with your team set up to run and extend it without us.
Let's build an app worth keeping.
A 30-minute call. We map what you want to build, tell you honestly what it takes, and scope a fixed price before you commit to anything.
