Quadrillages vs SDM 2022
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Quadrillages
This application helps users explore axial and central symmetry through interactive drawing on a grid. It covers Euclidean geometry concepts like points, lines, and angles, and can even be used for fraction initiation by dividing figures.
- Axial and central symmetry exercises
- Free drawing for Euclidean geometry
- Point, line, and figure drawing
- Angle and area calculations
- Fraction initiation through division

Placing a point on a grid, drawing lines, drawing figures as proposed by this application can appear as simple and easy. This is not the case and this application that makes it possible to work on the problems of axial and central symmetry is very rich. The "Free Drawing" part full of possibilities practically covers the field of Euclidean geometry: point, line, flat geometric figures, areas, mediator, diagonal, angles etc. Everything seems feasible and the initiation to fractions is even possible which makes it possible to divide a given line or figure into equal parts.
SDM 2022
Read full descriptionHide full description
L'application SDM 2022 est destinée à être utilisée dans un établissement scolaire (école primaire ou collège) dans le cadre de la semaine des mathématiques. Elle permet la mise en place d'un concours d'énigmes, sous la supervision d'un enseignant référent qui collecte les réponses et établit un (ou plusieurs) classements. FONCTIONNEMENT : Les énigmes sont disponibles à partir du 07 mars 2022. Chaque jour, dès minuit, l'énigme quotidienne est déverrouillée et peut alors être résolue. Chaque énigme comporte trois niveaux de difficulté croissante. En général, le niveau 1 est facile et permet de saisir les manipulations à effectuer. Le niveau 3 est difficile pour des élèves de primaire, qui pourront le plus souvent résoudre le niveau 2. TRAITEMENT DES RÉPONSES : Les réponses doivent êtres transmises au(x) professeur(s) organisateur(s), mais pas à l'auteur de l'application ! La réponse à donner est sous forme d'une capture d'écran, à envoyer par mail à l'adresse indiquée dans l'organisation du concours d'énigmes. L'application ne propose pas de correction des réponses.

Verdict
The clearest difference is price: SDM 2022 at Free against Quadrillages's $4.99. SDM 2022 also leads on update cadence (every 10 days vs every 5 months) and iOS requirement (10.0 vs 15.6). On ads, in-app purchases and device support there is nothing between them.
