We're UpFlyDev. We've been building software for twenty-something years now, for huge household names and for tiny two-person startups. Honestly? It's gotten pretty hard to surprise us.
New product? Old codebase nobody wants to touch? An AI idea you can't quite pin down? Bring it over. We'll find the smartest way to get it done, no drama, no wasted budget.
We move fast, keep things simple, and build stuff that just works.
What we shipped, what broke, and what we learned — from real products. See our apps Hire the team
Every mini-game now shares one tank of five hearts, refilling on the device's own clock with no server, no notifications and nothing to buy. Plus the engineering: a timer that needs no timer, why a heart you cannot watch leave reads as a bug, and the second heart that a held-open card was quietly costing.
solarpuzzlesreleaseengineering Read the postPlanet Blocks now teaches new rules as you climb: the Sun moves to a side and then roams, comets arrive as frozen blocks that never fall, and one of them lands in your tray so you choose where the trouble goes. Plus why a queued move is worse than a refused one, and a photo that stretched its own card on both platforms.
solarpuzzlesreleaseengineering Read the postA planner that picks the day for the date, the talk or the big ask; a journal that reads your own notes back to you; and a forecast that tunes itself to one relationship. Plus why the planner spaces its suggestions out on purpose, and where a personalised forecast is allowed to be computed when a watch only ever sees today.
cyclewingmanreleaseengineering Read the postNow live on both stores: a black hole that glows and spins as the marble chain closes in, a mercy brake for small hands, instant meteor burns and audio toggles on the pause screen. Plus a SwiftUI halo that inflated the thing it decorated, version strings that had quietly lied, and one shared version number across two stores.
solarpuzzlesreleaseengineering Read the postOur space puzzle collection for kids is live on the App Store and Google Play. The engineering: a measured 9 fps that killed the cross-platform plan, one Compose Canvas per board, level data that lives in exactly one place, and an app with no networking code at all.
solarpuzzlesreleaseengineering Read the postLog how the day actually went — mood, event tags and a private note on the calendar, and now from your Apple Watch too. Plus the engineering: a journal that deliberately stays out of the forecast, and the first data path from the watch back to the phone.
cyclewingmanreleaseengineering Read the postHome-screen widgets on iPhone and Android, Apple Watch complications, daily heads-ups and Face ID lock — plus the engineering behind them: a forecast cache instead of a third engine port, History-API back gestures inside a WebView, and a couple of WebView performance war stories.
cyclewingmanreleaseengineering Read the postOur first consumer app is live: your partner's cycle as a daily Green/Yellow/Orange/Red forecast. How we built an app with no servers at all — and kept two forecast engines in provable parity with golden fixtures.
