A: Hi,

Yes, this is a good fit for Swiftspeed. Let me map each requirement:

1. Sign up and create an account

Built in. The App Access feature handles user registration, login (email/password, Google, Apple), profile management, and password reset out of the box. Nothing to configure beyond turning it on.

2. Free introductory course (audio-based)

Covered by the Audio feature, which is purpose-built for streaming audio libraries with playlists, categories, cover art, background playback (continues when screen is locked), and offline downloads. You can mark certain tracks or playlists as free/public so anyone who signs up can access the intro course without paying.

3. Subscription + individual masterclass purchases

Two paths depending on whether you want it gated in-app or via your own backend:

In-app subscriptions and one-time purchases: handled natively through Apple In-App Purchase (iOS) and Google Play Billing (Android), which is the path Apple/Google require for selling digital content inside the app. You configure subscription tiers (monthly, yearly) and individual products (per-masterclass), and our platform gates access to content based on the user's purchase state.
External web-based subscriptions: if you prefer to sell on a web checkout (Stripe, Paddle, etc.) and have users log in to the app to access already-purchased content, that also works, common for course/membership models.
Hosting/streaming audio

You bring your own audio hosting. For each track, you either paste the direct URL to your hosted MP3/MP4 file, or configure cloud storage credentials (FTP, Amazon S3, Google Cloud Storage, etc.) at the feature level and the audio library streams from there. This gives you full control over your media costs and storage, and your files never leave your infrastructure.

Database

For your app's content (courses, masterclasses, tracks, categories), you manage it all from the editor backoffice, no separate database to set up. User data (accounts, purchases, progress) is stored on our platform automatically.

Recommended stack

App Access (accounts) + Audio (intro course and full library) + In-App Purchase (subscriptions and per-masterclass purchases). That covers your full requirement without custom development.

Best regards.
