Why ads break learning
Three reasons.
Concentration break. A 30-second video ad in the middle of a lesson shatters attention. Resuming takes 2 to 3 minutes.
Negative emotion. A frustrating ad creates a negative association with the educational app. Long term, you avoid it.
Disincentive to regularity. Many people abandon overly ad-heavy apps when they could have benefited.
The ad-free business model: three options
Honest freemium. Complete free version, premium for advanced features. That is the SAPIRO model.
Paid subscription. No free version. Anki model on iOS, some meditation apps.
Open source / non-profit. Khan Academy is a foundation. Wikipedia/Wikimedia.
Why SAPIRO chose ad-free
Three reasons.
Pedagogy. Learning does not tolerate ads.
Family. The app must be safe for children. No questionable ads.
Data. No advertising means no behavioral data collection. See our article on quiz apps without data collection.
How to know if an app is really “ad-free”
Three signs.
Is an account mandatory? If yes, there is probably data collection (which can fuel external targeted advertising).
Permissions requested. An educational app asking for contacts, location, mic must explain itself.
Privacy policy. Read the first lines. “No third-party advertising” is the phrase to look for.
