### 1/5 — Another fake free app

*2026-07-16*

This app is advertised as free but it is not. It’ll force you to pay no matter what. Beware.

### 5/5 — ありえへん

*2026-05-16*

### 2/5 — Déconseillé pour remplacer un lux mètre

*2026-03-05*

N’ayant pas mon lux mètre sous la main dans mon nouvel appartement j’ai utilisé cette application malheureusement elle est très peu précise. Elle indiquait une luminosité de 10 000 lux ce qui me paraissait cohérent avec ma baie vitrée. La vérité est que la luminosité n’était que de 3000 lux. Une différence colossale.

### 1/5 — Too expensive

*2026-02-02*

This app does what you’d expect from a light meter app, but $2.98/week is a RIDICULOUS subscription price.
