A calculation for every band
Each transmitter gets a frequency within its own band. Fixed transmitters are protected: they are never changed.
RF coordination for the field
A coordinated RF plan,
without intermodulation.
Yoobaa Freq calculates a compatible frequency plan for all your transmitters: TV, 5G and intermodulation are taken into account before the calculation. In the field, offline, in seconds.

The goal
A coordinated frequency plan,
not just a list of frequencies.
Every frequency is chosen to work with the others: TV channels, 5G, forbidden frequencies, fixed transmitters and third-order intermodulation are taken into account before the first calculation.
Features
Everything for a reliable RF plan.
From the TV survey to the final calculation, Yoobaa Freq brings the field constraints together in a clear interface, even on set.
TV, 5G and blocks
The TV channels in the area, the 5G 700/800 MHz presets and manual ranges are excluded from the calculation.
Intermodulation under control
Third-order intermodulation products and spacing between transmitters are taken into account on every calculation.
Your brands, your bands
Known bands and models are pre-filled, and each transmitter can use a custom band.

Configurations and exports
Recall a complete multi-transmitter system, export a CSV for the team and save everything as JSON to change phones.
Four languages, offline
French, English, Spanish and Dutch. Everything works offline, without an account and without sending your data. Dark interface, designed for the field.
In practice
Four steps, a reusable plan.
The setup is prepared once. Save it, then recall it when the same system comes back: each calculation adapts to the location and the fixed transmitters at that moment.
Describe the setup
Operating band, country and city, TV channels, 5G blocks and transmitters already tuned.
SETUP · location · blocksRun the calculation
The app assigns a compatible frequency to each transmitter that needs one, without touching the fixed transmitters.
1 tap · 16 transmitters to calculateSave the configuration
Save the complete system: transmitters, bands, frequencies, blocks and location. Up to 10 configurations in the full version.
1 to 10 configurationsRecall and export
Reload a configuration when the same system comes back, recalculate for the new location, then export the plan as CSV or a JSON backup.
CSV · JSON · Android sharingConfigurations save real time. For sound engineers, the same RF systems often come back from one shoot to the next, in the same city. Recall the full setup, run the calculation, and get your frequencies back without re-entering everything: a saved multi-transmitter system is a real advantage in the field.

Designed by a sound engineer, for the field.
Blitz Christophe has been a sound engineer for over 30 years, working in documentaries, fiction and ENG. He designed Yoobaa Freq from his own shooting setups: a reliable, readable RF plan that is quick to prepare, without needing a computer. A remark, an idea, a problem? User feedback shapes the app.
Frequently asked questions
What to know before the first calculation.
Does Yoobaa Freq work offline?
Yes. Calculations, configurations and exports all happen on the phone. The app needs no account and no connection.
Does the app measure the radio spectrum?
No. Yoobaa Freq calculates a plan from the band, location, TV channels and blocks you enter. It does not replace an on-site scan: always check the frequencies before shooting.
What is the difference between Free and the full version?
Free: 1 configuration, 6 transmitters and 1 custom location. Full: 10 configurations, 24 transmitters and 50 locations. The calculation, brands, exports and languages are identical.
Which transmitters are supported?
Zaxcom, Lectrosonics, Sony, Sennheiser, Deity, Wisycom, Sound Devices and Shure. Known models are offered, and “Other” lets you enter a custom model.
Can I export my configurations?
Yes. CSV export for the spreadsheet and the team, full JSON backup for archiving or changing phones.
Is my data sent anywhere?
No. No data is transmitted: everything stays on the phone. See the privacy policy.
Which devices is the app available on?
On Android, via Google Play. There is no iOS version yet.
