L'application Tropilég est dédiée aux problématiques phytosanitaires affectant les cultures légumières (et les tubercules tropicaux) des départements et régions d'outre-mer (DROM ou anciennement DOM) (Guadeloupe, Guyane, Martinique, Mayotte, La Réunion), de certaines collectivités d'outre-mer (COM) (Wallis et Futuna, Polynésie-française), et de Nouvelle-Calédonie. Elle a pour objectif d'aider les techniciens et les producteurs à identifier les maladies et les ravageurs affectant ces cultures, mais aussi à choisir des méthodes de protection respectueuses de l'environnement, et donc durables. Fruit notamment de missions réalisées dans les DROM, elle a été construite grâce aux connaissances et à l'expertise de plusieurs contributeurs appartenant à divers organismes de recherche et de développement de ces différentes zones de production.

Verdict
The clearest difference is in-app purchases: Tropileg at none against HydroCalc Basic's 1. Tropileg also leads on iOS requirement (12.0 vs 15.1). HydroCalc Basic's advantage is update cadence (every 11 days vs every 9 months). On price, ads and device support there is nothing between them.
