### 5/5 — Excellent Support

*2025-03-10, version 2.1.1*

I've been using the 1Contact app for a few months now, and while the app itself is quite useful, what truly sets them apart is their exceptional customer support. I recently ran into an issue , and I was honestly expecting a frustrating back-and-forth with generic troubleshooting steps.
Instead, I was blown away by the speed and efficiency of their support team. Within minutes of submitting my query, I received a personalized response from a real person, not an automated bot.
What impressed me most was their genuine willingness to help. They didn't just give me a quick fix; they took the time to understand the root cause of the issue and provided clear, concise instructions. It's rare to find a company that values its customers this much.
If you're looking for a contact management app with reliable support, 1Contact is definitely worth considering. Their team goes above and beyond to ensure a smooth and hassle-free experience. I highly recommend them!

### 5/5 — Recomendo

*2024-06-09*

Ótimo gerenciar de contatos, é possível excluir contatos duplicados, ou manualmente marcando vários de uma vez, entre outras funcionalidades. O diferencial dele é o valor, sendo uma compra única, sem esquecer que estamos no Brasil e aqui é tudo muito caro levando em consideração a nossa moeda, mas esse é um valor ótimo e entrega tudo muito bem! Podem comprar sem medo, é muito útil
