All world currencies.

A simple currency and cryptocurrency converter with real-time exchange rates and offline mode, but with aggressive advertising and stability issues.

The world's most downloaded calculator - Calculator₊

Calculator with unit converter for iPad, offered in a free version with intrusive ads and a paid version; after recent updates, it has stability issues and performs unreliably even in the paid version.

The app converts video to audio (MP3 and other formats), trims audio, sets ringtones, and applies basic sound processing.

The app provides a unit converter (currency, length, weight, volume, temperature, time, speed, pressure, energy) and basic calculator, but suffers from aggressive advertising, incomplete Russian localization, and unstable operation of the currency module.

An app for converting video, audio, images, and PDF files with a built-in player and editor. Format conversion and audio extraction work, but functionality is significantly limited in the free version.
