Are you a meditation teacher? Do you want an app to easily distribute and monetize your content? After the 10th person asked me (Toby) to build a meditation app for them, I decided to launch Brightlabs. We basically white-label Brightmind (my meditation app), and set you up with a state-of-the-art mobile subscription app that you can customize however you want. Over the last decade, we’ve refined our tech stack so your app will run smoothly on all devices, and you can add content with the click of a button. Here’s a full breakdown of what you’ll get * White label-app with custom branding * User onboarding * Content library * Gamification * Timer * Favoriting * Offline functionality * Reminders * As we add features to Brightmind, you’ll get them * If you want custom app features, we can build them * Update content easily at anytime * Fully scalable (even if millions of people download in a day, nothing will break) * 24/7 bug fixes * With a click of a button, we can deploy an app update to both iOS and Android * Email and push notification systems * Analytics * A/B testing * Automated crash reporting Revenue Apple’s App Store, by gross revenue, is now bigger than 90% of Fortune 500 companies. Let that sink in for a moment. People are used to buying subscriptions on their phones for content that they find valuable. The fact that Apple and Google already have their credit card information makes purchasing as easy as a thumbprint or Face ID. Launching a mobile app is one of the best ways to get paid for your hard work.
