Overview
Level 1: Minimal viable
Level 1 is the minimum viable integration. Your app works on the Timeback platform and follows the non-negotiables, but you keep your own learning engine, content formats, and algorithms.Technical requirements
Non-negotiable behaviors
These are tested during review. Apps that violate them will be rejected.- XP reflects real learning minutes (1 XP = 1 minute of focused learning)
- No XP below 80% accuracy
- Mastery verified before advancement
- Learning events are complete and accurate
Not required at Level 1
You keep your own:- Learning engine and algorithms (e.g. no PowerPath)
- Content formats (e.g. no QTI)
- Placement and diagnostic logic
- Spaced repetition implementation
Level 2: Fully native
Level 2 apps use Timeback’s learning systems instead of building their own. You read Timeback’s placement data and act on it. You use our learning engine, content formats, and spaced repetition algorithms.What changes from Level 1
Why Level 2
- Don’t reinvent placement, sequencing, or spaced repetition
- Your app automatically benefits from platform-wide improvements
- Deeper analytics and cross-app progress sharing
What to expect during review
The Timeback team checks your app against the non-negotiables and Level 1 requirements.
If your app does not meet requirements, you receive specific feedback and can fix and resubmit.
