## What is Whatool?

Carry out advanced searches within your WhatsApp Messenger, Line and Viber chats.
You can search by date, sender and by message content.

The importation process is designed to be as simple and secure as possible: the chat data processing is carried out directly within your device to avoid sending your sensitive information to external servers*.

The new "MERGE" mode allows you to merge multiple conversations in one combined display, from which you can search and view the message history as if it were one single conversation.

Importing your chats to Whatool is also useful for keeping a second, backup copy of your messages: this reduces the risk of losing important information and memories you wish to keep hold of.

Whatool is FREE. Try it now, it costs you nothing!

### 5/5 — Lambona

*2020-02-18*

Gracias

### 5/5 — Impresive search function

*2017-03-15*

I can't speak to any other functions, but I was amazed by the search function. I needed to find one specific message in a WhatsApp conversation from 3 months ago. I figured it would take ages for the ap to import the convo and then search through the 7000+ messages, but it took seconds!! Very impressed.

### 1/5 — It doesn't work

*2016-02-21*

Don't waste your money. This app doesn't work. I used it to save viber messages and it only saved/transferred the messages for only one day. It says that the app it's free but as soon as you try to transfer the data they ask you to pay .99 because you exceed the data transfer. I paid and like I said it only transferred messages for only one day and I wanted to save messages from Viber for a month. Useless app.

### 5/5 — Powerful tool

*2016-01-10, version 1.7*

Have you ever tried to find a particular conversation within a chat you have been having with someone over two years.... It's difficult, Viber especially has a very unhelpful search tool built in, most of the time it feels like it just chooses a random conversation and offers it as a consolation prize for your efforts. Whatool gives you a powerful search tool that lets you import your conversations and gives you control over masses of information . Search using a choice of different variables including dates and text . Only drawback is the data exported from viber doesn't include if a call was made or not. Hmmmm defiantly a thought for the next version ... Anyway great tool download it . 
Ps great for couples needing to resolve what was said when and why lol....

### 4/5 — Awesome

*2015-08-03, version 1.5*

Great to have the ability to search massive whatsapp threads

### 1/5 — No functionality. Everything crashes

*2015-06-10, version 1.4*

Almost every time you interact with this app, it crashes. Doesn't even come close to functioning

### 1/5 — Constant crashing

*2015-06-05, version 1.4*

Constant crashing, unusable. Please update.

### 1/5 — Doesnt do anything (iPhone6)

*2015-06-03*

A pretty interface with no features. I couldn't find a way to do anything except purchase something or delete the test convo (which they apparently forgot to delete themselves). Clicking on either help button immediately crashes the app every time.

### 1/5 — Crash Test Dummy, apparently

*2015-06-02*

I feel like an unseatbelted crash test dummy.  Thanks for nothing.

### 1/5 — Useless

*2015-05-23*

The app keeps crashing... Useless
