We don't chase categories. We pick one thing people actually do, then build the app that does it best.
Kids & bedtime
Tell Dreamify about your child once: nickname, age, favourite animals, toys and places, and anything you'd rather it never mentions. Each evening it writes a brand-new fairy tale with your child as the hero, draws a picture for it and reads it aloud, in a calm narrator's voice or in yours. A sleep timer fades everything out on its own.
Manifest & affirm
Answer a few questions about who you are and what you're working toward. Instead of a generic affirmation, Viola writes short scenes from inside that life, with your city, your work and your own details, and reads them to you in one of six voices. A fresh deck of affirmations arrives every morning.
Loyalty, built for a brand
Built for GERG Stroop & Coffee. One QR code at the till, points that land on your account the moment the receipt is confirmed, six membership tiers from Bronze to Diamond, and a stamp card that turns eight espressos into a free stroopwafel. The live menu carries photos, prices and allergen details.
Every app follows the same path, from a single everyday moment to a product people keep on their home screen.
Bedtime. The first quiet minutes of the morning. A coffee on the way to work. We pick one moment and get specific about what would make it better.
A story with your child's name in it. A scene set in your own city. A card with your own stamps on it. Personal detail is the feature, not a setting.
A first version in weeks, not quarters. Reviews, support mail and usage data decide what the next release is.
Voice, narration, subscriptions and analytics are shared across apps, so each new product starts further ahead than the last.
KNT App Studio was founded in 2026 by Osman Kantarcıoğlu. We keep the team small on purpose, so every app has someone who knows it end to end: the design, the code, the store listing and the reviews.
Our first three apps went live within three months of each other. Two of them put the user's own voice and details at the centre; the third runs the loyalty program of a coffee shop. That range is deliberate. We want to be good at consumer apps and at building for brands.
We're not hiring right now. If you build iOS apps and want to be the first hire, write to us anyway.
We also take on mobile app development for brands. GERG started as a request from a coffee shop that wanted its regulars to stop carrying paper stamp cards. If your business needs an app customers actually keep, we design and build it, from the first sketch to the App Store listing, and keep improving it after launch.

Apple Search Ads, App Store Optimization and social campaigns, run the way we run them for our own apps. Close to $100,000 a month in ad budget under management, in accounts that stay yours.
We are an independent iOS app studio. We design, build and publish our own consumer apps, and we build apps for brands that want one under their own name.
Three so far: Dreamify, personalized bedtime stories for kids read in your own voice; Viola, a manifestation and affirmation app that writes personal scenes; and GERG, the loyalty app of GERG Stroop & Coffee. All three are free to download on the App Store.
Not yet. Our apps are built for iPhone and iPad and require iOS 16.4 or later. Android is on the roadmap for products where it makes sense.
Yes. GERG was built for a coffee shop that wanted to replace paper stamp cards. We take on brand apps from the first sketch to the App Store listing and keep improving them after launch. Write to info@kntappstudio.co to start a conversation.
We collect only what an app needs to work, such as the details you enter for a story or your membership in a loyalty program. Voice recordings in Dreamify are used only to narrate stories and can be deleted at any time. The full details are in our privacy policy.
Everything on this site comes from running our own apps and our own ad accounts, and from the teams we work with. The blog is organised into five topics, each with a hub page. If you are deciding whether to spend on Apple Search Ads, working out what a loyalty app for a cafe really needs, or trying to ship as a small iOS team, start with the hub and read the posts at the top. We publish one new piece most days, chosen from what people actually search for.
