livetoolkit vs VR Mobile
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
livetoolkit
This app provides essential calculations for live event technicians, including PA system setup, lighting fixture addressing, and electrical measurements. It helps speed up on-site setup by offering quick conversions and calculations directly on a mobile device.
- PA system delay time calculations
- Subwoofer stacking distance calculations
- Q-Factor to Bandwidth conversion
- Limiter calculations for speaker capacity
- Tap Tempo calculation
- DMX fixture addressing
- Unit conversions (feet/meter, lbs/kg)

Everybody working in the live concert business has experienced situations like this: You've just arrived at the venue. According to the local promoter everything should have been put up before you arrived, but it hasn't. Now it'll take an hour or more to set up the PA-System and Lighting-gear before you can start to do your actual work. All has to be done as fast as possible. You don't have time to get your laptop out of the car and working just to do some necessary calculations. Now you can just take your iPhone®, iPod touch® or iPad® and start doing your calculations with LiveToolkit. LiveToolkit helps audio technicians to make relevant calculations directly with his or her iPhone®, iPod touch® or iPad®, like: • Delay times for your PA-system: Conversion between time and distance. • Stacking distance of your subs: Conversion between frequency and wavelength. • Getting your PA-Settings into the controller: Conversion from Q-Factor to Bandwidth and back. • Setting up your controller: Limiter calculations depending on speaker capacity and amp output. • Getting the musicians tempo: Tap Tempo calculation with different note weightings. LiveToolkit helps lighting technicians to make relevant calculations directly with his or her iPhone®, iPod touch® or iPad®, like: • Getting the start address for multiple fixtures based on quantity, channels, and first address used. • Setting the DMX-address right using a DIP-Switch, or identifying the address value of a DIP-Switch. LiveToolkit helps any technicians to make relevant calculations directly with his or her iPhone®, iPod touch® or iPad®, like: • Universal useful conversion between feet and meter and lbs to kg. • Conversion between Watt, Ampere and Volt. • Calculate the voltage drop in your cable based on length and profile. • Trigonometric calculation on heights based on angle & distance. IMPORTANT NOTES: • Although good tested - this application remain a piece of Software: rockbaby engineering will not take any responsibility for any issues that may occur using LiveToolkit.

Verdict
The clearest difference is price: VR Mobile at Free against livetoolkit's $3.99. VR Mobile also leads on rating (4.7 vs 2.0) and review sentiment (100% vs 75%). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
VR Mobile is free to download; livetoolkit costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
VR Mobile holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: VR Mobile has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 75% of livetoolkit's written reviews are positive against 100% of VR Mobile's.
livetoolkit ships an update every 11 months, VR Mobile every 4 months. The most recent releases landed on July 1, 2026 and September 9, 2026 respectively.
