BRAINSTORM & IDEATE Sometimes you need a more visual setting for coming up with new ideas for a specific topic. Or you want to do a brainstorming session in a more organized way.

Verdict
The clearest difference is price: Doo at $4.99 against Ideafall's $29.99. Doo also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (39 vs 1). Ideafall's advantage is review sentiment (100% vs 55%) and rating (5.0 vs 4.4). On ads, in-app purchases, monetization model and device support there is nothing between them.
