L’IGN (Institut national de l’information géographique et forestière) met en place l’application Aléa. Cette application est un outil collaboratif de signalement. Elle permet d'envoyer simplement des signalements dans le cadre d'une campagne de recueil d'informations. Ces signalements pourront, par exemple, permettre de constituer une cartographie de ces observations consultable sur internet qui aidera les autorités compétentes dans le traitement des informations recueillies.

Verdict
The clearest difference is in-app purchases: Aléa at none against Cadastre's 6. Aléa also leads on iOS requirement (11.0 vs 15.0). Cadastre's advantage is update cadence (every 4 days vs every 26 months) and review sentiment (71% vs 50%). On price, ads and device support there is nothing between them.
