Lightcert is a live entertainment app that combines tech and art to bring fans together. Lightcert transforms the audience into part of the show itself, creating an interactive experience like no other. Select your show and section, record, and light up the stadium!

* Connect
Choose your stadium and section using the sliders. Other audience members will do the same.

* Record
Choose the song currently being performed. This will launch front camera recording.

* Light
While recording, hold up your phone and use the phone’s screen to light up the concert! Everyone in your section will have the same color, but every section will have a different color.

A note from the developer:

Hi all, this is Bailey here.

I made this app during my senior year of high school because there was a pandemic and nothing else to do (haha) - honestly, my initial reason for doing it was just because creating this seemed easier than coordinating a sticky-note based project, and I was interested in mobile development at the time.

Currently, Team Lightcert is Emma and Sarah, who largely handle the social media, and me, the developer. We’ve worked really hard on creating this for everyone, and we hope you all like it :)

If you’d like, please leave us a review! We loved reading your guys’ reviews from our beta test. And also, don’t forget to follow us on TikTok (@loveontourlights) and Instagram (@lightcertapp) and tag us in your posts!

Lastly, because this is a project, it’s probably safe to assume we’ll have semi-frequent updates, but we’ll let y’all know through social media.

absolutely solid.

yo this app- I’m going to see Harry on September 29 and I’m so pumped and this app and the whole idea of the app just makes me even more excited. If been to concerts in the past for other artists and we’ve always used tape and so now that we can just use our phone screens AND VIDEO is golden, (see what I did there). anyways I’m so excited for this and I’m so glad that the creators came up with this!

Definitely solidified the fact that Love On Tour is happening

I saw a post from a Harry fan account I follow telling their followers to download the app for the concerts, and I’m amazed!!! It’s such a clever idea and so creative, plus there’s 3 songs to light up arenas to!!! I think that’s incredible and it’s going to make Love On Tour so incredible.

awesome & easy to use!

I’m so excited to get to use this app for my show!! I’ve always wanted to be a part of a fan project so that we can show Harry how much he means to us and how much we love him, and now I’ll easily be able to do that with this app.
