## Most critical reviews (10 lowest-rated)

### 1/5 — Very poor advertising

*2022-07-24, version 5.1*

Let’s you get 3/4 of the way through your calculations and then locks you into an advert that wouldn’t interest you in the slightest when you are trying to size an aircon unit!!!!

### 1/5 — Do not pay for the app !!

*2022-02-24, version 5.0*

I paid the small fee to get rid of the Ads but they still come back meaning if you use it a lot you have to keep erasing it to use again very frustrating 🤬

### 2/5 — Has Potential

*2021-12-31*

Does not include east and west windows or factor in insulation, ceiling height, etc. I'll just stick with my free, homemade excel calculator instead.

### 3/5 — EVALUACIÓN

*2020-10-12, version 4.0*

Es sencilla y da una idea aproximada de BTU’s a reemplazar, pero la pueden mejorar, considerando materiales, remplazo de aire, asoleamiento en losas, etc.
La calificación que doy es porque se cierra la aplicación antes de poder ingresar todos los datos
