Independent iOS development · Ankara
Apps that show you what happens next.
I'm Okan Coskun. I build small, focused iOS tools on my own — a tactical round simulator for CS2, and two trackers that keep a habit honest. No accounts, no dashboards, no upsell.
Shipping record
Three apps, one developer
Every line of code, every icon, every App Store screenshot. Built in Flutter, released under my own name.
Who is behind this
Okan Coskun
I lead a multilingual customer-service operation by day — teams across several sites, three languages, targets that don't move. Apps are what I build after that.
That job shaped how I write software. I spend my working hours watching people get stuck in badly designed tools, so when I build my own I strip out anything that isn't doing a job. No sign-up wall in front of a water tracker. No cloud sync for data that has no reason to leave your phone.
Tactix came out of the opposite problem: something genuinely complex that nobody had built properly. Drawing arrows on a radar image tells you nothing about whether a strat works. So I wrote the part that does — sightlines, occlusion, weapon ranges, reaction times — and let it answer the question honestly.
Everything here is solo work: the code, the interface, the icons, the store listings, this website.
