### 4/5 — Earth PI

*2026-05-01*

Bon application, dommage qu’on ne puisse pas l’avoir sur ordinateur et qu’on ne puisse pas la mettre en français, je compte sur vous pour améliorer ça. Sinon j’aurais mis à cinq sur cinq. Et pouvoir aussi avoir plus de fonction au niveau des dates pour remonter en arrière pour analyser comment aurait été le soleil et la lune il y a une semaine ou trois mois on a en arrière par exemple pour voir si ça colle avec nos observations.
