*2018-12-03*

Super helpful!

### 4/5 — Très utile

*2018-10-24, version 1.0.1*

Très utile pour calculs de durées fiscales (durée de détention, valeurs d’usufruit/nue-propriété, abattements...). Mais la date saisie se réinitialise dès que le téléphone se verrouille et le mode de saisie des dates n’est pas très pratique (scrolling).
