### 5/5 — Perfeito!!

*2020-11-01, version 1.07*

Muito bom.

### 1/5 — Inútil

*2020-04-17, version 1.07*

App inútil, se vai mandar do pc pro celular já abre logo no pc, falta a FuelTech fazer produtos mais pensados na praticidade, a ft600 que hoje é topo de linha custa quase 10 mil reais e mesmo assim não é um produto completo se você pensar na praticidade, poderia ter conexão bluetooth para se conectar ao celular e um app descente para trabalhar em conjunto, estamos em 2020 FuelTech, vamos evoluir em praticidade.
