Looking for a meditation app for custom MP3s + journaling after each session (with stats). Does this exist?

Hey everyone,

I’m trying to find a very specific type of meditation app and I’m not sure if it even exists yet, so I thought I’d ask here.

I don’t want another subscription app with built-in guided meditations.
Instead, I want an app that works with my own MP3 files, from different sources (not just Dr Joe's).

What I’m looking for:

• Custom MP3 support
  • I want to add my own meditation files (from different teachers, courses, etc.).
  • Ideally it should handle files from different sources (local files, downloads, etc.).
• Cloud storage support (nice to have)
  • Being able to store/stream from Google Drive / Dropbox / Mega / etc. would be amazing.
  • Cross-device syncing so my library is the same on phone, tablet, maybe desktop.
• Post-meditation journaling / form
  • After each meditation finishes, I want the app to prompt me to journal.
  • Ideally a simple form or template every time, e.g.:
    • mood before/after
    • short text note
    • maybe tags like “anxiety”, “sleep”, “focus”, etc.
• Statistics / tracking
  • Basic stats: total time meditated, streaks, days practiced, etc.
  • Bonus: graphs, history, maybe even stats per specific track or tag.
• Cross-platform
  • At least mobile (iOS/Android), but desktop or web app would be a huge plus.

Basically I’m imagining:

I’ve seen music players that work with cloud storage, and I’ve seen meditation timers with logging, but I haven’t found one app that combines: custom audio + automatic journal prompt after each session + statistics.

Does anything like this exist already?

• If yes: what’s it called and what platforms does it support?
• If not: what combo of apps are you using to get something similar (e.g. one app for audio, one for tracking/journaling)?

Thanks in advance for any recommendations 🙏
