Senior iOS Developer · Istanbul, Türkiye

Hi, I'm Aydın.
I make apps for Apple platforms.

I build polished, privacy-first apps for iPhone, iPad, Mac and Apple Watch. I work at DFDS, where I build their logistics and passenger apps. In my spare time I design, build and ship my own apps.

Selected work

Apps I've built and shipped

Independent apps that I designed, built and published myself, all live on the App Store.

SitFocus

Focus timer with an on-device posture coach

App Store

A Pomodoro timer that notices when you slouch and nudges you before your back starts to hurt. Posture detection runs entirely on the device: camera frames are analyzed in memory and never recorded, stored or uploaded.

  • Real-time posture detection with Apple's Vision framework
  • Personal calibration so alerts adapt to your body and desk
  • Pomodoro sessions, Live Activities and widgets
  • Tasks, subtasks and a 30-day posture trend

HealthLoop

Nutrition, workouts and recovery in one place

App Store

Most health apps make you choose between counting calories and logging lifts. HealthLoop tracks what you eat, how you train and how you recover in one app, and syncs everything with Apple Health.

  • Barcode scanning and on-device AI food estimates from a photo
  • Weekly meal plans with shareable shopping lists
  • 200+ exercises, a workout planner and Live Activity rest timers
  • Apple Watch companion and home-screen widgets

Islam Guide

Prayer times, Qibla and the Holy Quran

App Store

Brings daily worship into one simple, privacy-respecting app: accurate prayer times for your location, a precise Qibla compass, the Quran with translations, weekly Friday sermons and a digital tasbeeh.

  • Prayer times from trusted calculation methods worldwide
  • Qibla compass and nearby mosques on the map
  • Private, on-device Q&A powered by Apple Intelligence
  • Prayer tracking, notifications and widgets

Who is Calling

See who's behind unknown calls

App Store

Missed a call from a number you don't know? See what other people reported about it before you call back, and warn others about scam calls in seconds. No sign-up and no access to your contacts.

  • Community reports with a clear risk level for every number
  • Categorized reports: bank impersonation, delivery scams, robocalls…
  • Comment voting brings the most helpful reports to the top
  • Share a number straight from Contacts. Only the number is saved

Ratery

Rate and track what you own

App Store

A personal rating journal for everything you own, watch, read and taste. Create your own categories, then add items with a photo, a score out of 10 and the notes you'll want later.

  • Custom categories: movies, books, restaurants, vinyl…
  • Scores out of 10, because an 8 and a 9 aren't the same
  • Barcode scanning fills in the title, author and cover art
  • Owned and wishlist filters, plus insights across your collection
