Utility apps for iPhone, made in Tallinn.
Zino Grupp OÜ develops, publishes and supports four apps on the App Store. All of them are free to download, with optional subscriptions.
Our apps
PixSweep Cleaner
Frees up storage by finding similar and duplicate photos, screenshots, oversized videos, duplicate contacts and outdated calendar events. Items are grouped for review, processed on the device, and deleted only when you confirm.

Bedtime Nudge
Set your wake-up time and how much sleep you need, and the app works out your bedtime and nudges you 30, 45 or 60 minutes before it. Includes a countdown to wind-down and a separate weekend schedule.
A reminder app — not a medical or sleep-tracking device.

Waterlio - Add Watermark
Adds text or logo watermarks to photos. Adjust size, position, rotation and opacity, save styles as reusable templates, apply them to several photos at once, or tile a watermark across the whole image. Photos are processed on the device.
View on the App StoreCompany
Zino Grupp OÜ is registered in Estonia and works out of Tallinn. We publish our apps under our own name on the App Store and handle development and support in-house.
Each app covers one clear task, needs a short setup, and runs on iPhone with iOS 17 or later. Privacy policies and terms for every app are linked from its entry above.
