Independent software studio
Audio, video & privacy
Turbo Ventura builds audio, video and privacy tools for iPhone, iPad, Mac and Apple Watch, with Android and TV versions on the way. We compile our own media engine rather than renting someone else’s, keep files where their owner put them, and stay with an app long after the release note.

Convert video and audio to 38 formats, separate a song into its instruments, and edit on a multitrack timeline — twenty-five tools in one app. The work runs on the device, with no account and no upload.

Hide photos, videos, notes and documents behind 256-bit encryption, Face ID and a decoy vault that shows something else. The app can even open as a calculator.

Bring your music and video in from Wi-Fi, your Apple Music library, the cloud or your NAS, and play it offline with gapless playback, a 10-band equalizer and synced lyrics. Podcasts and radio are in the same app.

Play the IPTV playlist you already have — Xtream Codes, M3U, or your Jellyfin, Emby or Plex server — on the car’s screen with CarPlay, on a TV over Chromecast and AirPlay, and on Apple TV. It mirrors other apps to the car and the TV too, and comes with no channels of its own.

209 calculators for salary, tax, credit, health, maths and time, in Romanian, English and Turkish, with the payroll and tax rules of Romania, Türkiye and the UK. The arithmetic runs in your browser, and an app for iPhone, iPad and Android is on the way.

In the accent, what calcula·live’s 209 calculators cover. In plain type, the countries whose payroll and tax rules they follow.
01
MP3 Converter runs on an FFmpeg build we make from source — LGPL-clean, with only the codecs we actually ship enabled. It is more work than linking somebody else’s binary, and it is why a file that fails everywhere else usually opens here.
02
If what is inside a file can be copied out untouched, we copy it instead of re-encoding it. The result is the original bits rather than a copy of a copy, and it finishes in seconds. Most tools re-encode everything, because that is the easy path.
03
Pic Vault encrypts every file with 256-bit ChaCha20-Poly1305 under a key of its own, and seals the keys with your passcode on the device. File names and albums are encrypted too, so even the list of what is inside gives nothing away.
04
The strongest vault is one that does not look like one. Pic Vault can open as a working calculator, hand over a decoy vault with its own passcode, and photograph whoever guessed the wrong code.
05
Turbo Music plays the music you own, not a catalogue you rent. It fetches your files from Wi-Fi, a cloud drive or your NAS once, then plays them gapless on a plane or in a tunnel — and even writes the lyrics on the phone when nobody else has.
06
xTV puts the IPTV subscription you already have on the car’s screen, the TV and Apple TV — and ships no channels, no playlists and no links to anyone selling them. It plays what you bring, and the stream travels from your provider to your screen without passing through us.
07
calcula·live keeps each country’s rates for the year in one place, and every calculator reads them from there. The site is rebuilt from it and the coming app downloads it, so a new budget reaches the phone without waiting for a store update — while the figures you type stay in the browser or on the phone.
08
Conversion, editing, AI separation, lyrics and encryption run locally. There is no upload step, no account to create, and nothing of yours waiting on a machine we own — a file leaves the phone only when you send it somewhere yourself.
09
The media and privacy apps are SwiftUI, drawn for iPhone and iPad and for the current version of iOS: Dynamic Type, VoiceOver, Face ID, the share sheet, the lock screen, widgets. The system already decided how these work, and their Android versions will be built for Android rather than ported to it. calcula·live’s coming app is the exception: one Flutter app for iPhone and Android, because its calculators are the same everywhere — drawn as an app rather than a web page in a frame, and still counting on the phone.
10
The free tier does real work. What a purchase removes is quantity and convenience — never the feature the app is named after, and never with a countdown to force the decision.
11
An app is not finished at release. Ours get format fixes, security updates, new iOS versions and the small repairs nobody writes a changelog line about, for as long as people are using them.

We take on a small number of partnerships a year: publishing an app that deserves a better home, or building one with a team that needs the hard media parts done properly. Press and store enquiries reach the same inbox.
