The America’s Got Talent app has become the go-to tool for fans voting on Season 21, especially now that Live Quarterfinals started August 18. NBC’s talent competition just moved from taped auditions into live voting rounds, and the app sits at the center of how millions of viewers decide who advances.
Season 21 features judges Simon Cowell, Sofía Vergara, Mel B and Howie Mandel, alongside host Terry Crews. The season kicked off June 2 with a new Judges’ Callbacks twist that gave select acts a last shot before reaching the live rounds.
What the App Actually Does
The America’s Got Talent app lets fans play along at home while watching the show on NBC. It’s free to download on iOS and Android, and it works alongside every live broadcast.
Core features include:
- Live voting during Quarterfinals, Semifinals, and the Finale
- Personalized buzzers loaded with judge sound bites from Simon, Sofia, Mel B and Howie
- Act profiles with bios and background on each performer
- Social links to follow acts on TikTok, Instagram and Facebook
- Login through an NBCUniversal Profile to sync votes and preferences
On Google Play, the app currently holds a 4.2-star rating across more than 10,500 reviews. It was last updated in late July 2026 to reflect the Season 21 judge lineup and branding.
Top 44 Acts Move Into Live Quarterfinals
NBC revealed the official Top 44 acts advancing to the Live Quarterfinals, which began August 18. The lineup mixes singers, dancers, comedians, magicians, stunt performers and viral social media newcomers, all handpicked by the judging panel.
The Quarterfinalists include all 10 Golden Buzzer recipients from this season, plus acts selected through the new Judges’ Callbacks round. Fans can now use the America’s Got Talent app to directly influence which of these acts move forward.
Three Ways to Vote This Season
Season 21 introduced a notable change to how fans can support their favorite acts. For the first time, voting isn’t limited to the app and website.
Viewers now have three official voting methods:
- The AGT app — vote directly through the mobile platform
- The NBC website — vote online without downloading anything
- TikTok comments — vote by commenting on the show’s official TikTok voting posts
Each method allows up to 10 votes, and the voting window closes every Wednesday morning at 7 a.m. ET. This TikTok integration marks the first time AGT has opened voting through a social platform, reflecting how much of the show’s audience already engages with acts online.
Live Show Schedule for the Rest of Season 21
Episodes now air live, meaning results genuinely depend on real-time voting through the app and other methods. Here’s the confirmed schedule for the remainder of the season:
| Round | Dates |
|---|---|
| Live Quarterfinals | August 18 – early September |
| Live Semifinals | September 15–16 |
| Live Finale | September 22 |
| Results Show | September 23 |
New episodes continue to air Tuesdays at 8 p.m. ET on NBC, with results shows following on Wednesdays. Every episode streams the next day on Peacock for viewers who miss the live broadcast.
Why the App Matters More During Live Shows
During the taped audition rounds, the America’s Got Talent app mainly offered entertainment extras like buzzers and act bios. Now that the competition has shifted to live episodes, the app carries real weight — votes cast through it directly determine which acts survive each week.
Terry Crews continues hosting the live rounds, working alongside the judging panel to reveal which acts move on after each voting window closes. Simon Cowell, in his role as executive producer, has spoken about wanting this season’s live shows to feel more unpredictable than in past years, partly because of the expanded voting options.
Golden Buzzer Highlights Shaping the Quarterfinals
This season already delivered a milestone moment: the show’s first-ever three Golden Buzzer night, kicked off by performer Lai Noelle during the audition rounds. That night set a tone for a season packed with standout moments, from aerial acts to emotional vocal performances.
Ten total Golden Buzzer recipients earned automatic passage into the live rounds, joining acts selected through Judges’ Callbacks to fill out the Top 44. Viewers who want to revisit these moments can find full clips through the NBC app and AGT’s official social channels, alongside the voting tools built into the AGT app itself.
Getting Started With the App
Setting up the America’s Got Talent app takes just a few minutes:
- Download the app from the Apple App Store or Google Play
- Log in with an NBCUniversal Profile
- Browse act profiles to catch up before Live Quarterfinals
- Enable notifications for reminders when voting windows open
- Cast votes during the live broadcast, up to 10 times per method
If the app freezes or crashes during a live voting window, NBC recommends fully closing the app, restarting the device, and reopening it before trying again.
What’s Next for Season 21
With Quarterfinals underway, the competition narrows quickly. Semifinal performances arrive September 15 and 16, followed by the Live Finale on September 22 and the Results Show on September 23, when Season 21’s winner gets crowned.
Fans hoping to influence that outcome will want the America’s Got Talent app ready well before each Wednesday cutoff. Between the app, the NBC website, and TikTok voting, Season 21 has given viewers more direct influence over the competition than any previous season.
