Frequently Asked Questions

One4Studio is a mobile app development studio creating premium apps for Android and iOS. We build personalization apps, utility tools, and more — including icon packs, 4K wallpapers, photo and video compressors, and cooking apps. Trusted by over 3 million users worldwide.

We offer icon packs (Vera, Lena, Ares, Caelus, Adaptive), wallpaper apps (One4Wall, Thematica), widget packs (One4KWGT Pro, One4KWGT Reloaded, Nora for iOS), WearOS watch faces (Neuron), the SlimPix photo and video compressor for iOS, and the Vule recipe and cooking app for iPhone and iPad.

Yes! One4Wall, Thematica, SlimPix, and Vule are available on the iOS App Store. Our Vera, Lena, and Ares icon packs are also available for iOS through Gumroad, with instructions for applying them using the Shortcuts app.

Custom icon packs let you replace default icons on your home screen with designs that match your style. They unify your device's look, making it more cohesive and polished. Our packs include icons, wallpapers, and KWGT widgets — everything in one app.

Nova Launcher, Lawnchair, Niagara Launcher, Smart Launcher, Action Launcher, and Apex Launcher all support third-party icon packs. Samsung users can use Good Lock's Theme Park module. Pixel Launcher does not natively support icon packs.

Install a supported launcher, then open its settings, navigate to the icon or theme section, and select your installed icon pack. We have step-by-step guides for each launcher in our Guides section.

Vera features shapeless colorful icons (7,000+). Lena is minimal and bold with shapeless design (6,000+). Ares uses squircle shapes (5,500+). Caelus features linear outline-style icons (5,000+). Each comes in multiple color variants.

We offer a full refund within the first 7 days of purchase, no questions asked. Google Play also offers refunds within 48 hours. We update our packs every week or two with new icons.

Open the icon pack app, tap the Request card, select up to 10 apps you want themed (with free request), and send the request. Premium requests get priority and are fulfilled within 1-2 updates.
