4E is the home of the electronic music scene โ artists, sets, events and clubs, all in one app. DISCOVER ARTISTS Explore DJ and producer profiles, listen to sets and tracks in the in-app player and follow the artists you love. The music keeps playing while you browse other pages. KEEP UP WITH EVENTS See the full line-up by stage and set time, and tap a stage to open its schedule. Ticket tiers are listed on the event page with a direct link to the official ticketing site. Use the interactive venue map to find your way around with ease โ stages, food court, restrooms, first aid, showers, water stations, parking and exits โ and check the menu at each food spot. LIVE MAP (OPTIONAL) At events that turn this feature on, you can join the live map and see who from your crew is nearby. It only works if you opt in: your location is sent only while the map is open, stays in the server's memory for 45 seconds and is never written to disk. You can leave the map or block someone at any time. DANCEFLOOR TALK Join communities, chat on the forum, arrange rides to the party and send direct messages to other people in the scene. GET TO KNOW THE CLUBS Stay in the loop on the scene's venues and collectives, with their schedules and latest news. YOUR SPACE Build your profile, follow artists, RSVP to events and get alerts about upcoming dates. Sign in with email, your Google account or your Apple Account, and delete your account at any time right from the app. FOR ARTISTS AND PROMOTERS For artists, event promoters and clubs, 4E is also your publishing tool: create your page, upload your sets, build the line-up, promote your ticket tiers, design the venue map and talk directly to your community. Creating an account, publishing your page and using the forum are free. ARTIST PRO (SUBSCRIPTION) Artists can subscribe to Artist Pro in the app, billed through the App Store, on a monthly or annual plan with automatic renewal. Payment is charged to your Apple Account when you confirm the purchase, and the subscription automatically renews for the same period unless it is canceled at least 24 hours before the end of the current period. Cancel anytime in Settings > [your name] > Subscriptions.

Verdict
The clearest difference is in-app purchases: ESX Toolkit at none against 4E Music's 4. ESX Toolkit also leads on iOS requirement (12.0 vs 15.0). 4E Music's advantage is update cadence (daily vs every 5 months). On price, ads and device support there is nothing between them.
