## What is IsI Notebook?

With IsI Notebook you can quickly write and read notes.

IsI Notebook is a small notepad app. With IsI Notebook data can be stored and retrieved rapidly on two different notepads.

As in-app purchase more functions can be activated. For just 99 cent each user has access to 3 more notepads (6 in total) and can change the font size and font (5 different fonts). You also have the option to remove all ads from the app.

This app is based on my findings from the IsI notepad that can also be downloaded here in the AppStore. The main difference to the classic notepad is that two different text fields can be filled at the same time (like a book). So you have the opportunity to save more different notes on one screen. I did not implement more functions because I want to continue to develop the app in collaboration with the users. So test the app and tell me what features you would like to have for the future and I will try to develop this. But feel free to give my app a positive feedback if you like it ;)

### 1/5 — Awful APP

*2023-06-14*

It has no functions, you can’t save anything. Anything you do write is lost when you back to it. Waste of time there must be better out there.

### 5/5 — Also please make is auto save

*2022-10-07, version 1.2*

Thanks

### 2/5 — Options?

*2022-03-02, version 1.2*

There’s no options from what I can tell. I don’t even see a way to save my work and when I push the sprocket at the top for settings it kicks me back to the home screen and close the app. Luckily when I open it back up what I was doing is still on the screen.

### 1/5 — Sehr schade Geld um fester raus geworfen

*2021-11-24, version 1.2*

Das ist schon recht merkwürdig…. Was sich da der Anbieter leistet. 
Man Kauf und muss dann nochmals Geld zahlen damit die Werbung verschwindet. Das ist so, als wenn man jedes Rad am Auto separat kaufen müßte….
Na ja…. Ich den mal.. so werden sie keinen Erfolg haben 
Ein sehr verärgerter Käufer.

### 5/5 — Best

*2020-10-16, version 1.2*

I have had this app I love it

### 1/5 — Very stupid app

*2020-03-26, version 1.2*

After typing my text (one font available only), i closed the app and lost everything I typed.  The Setting button, numbers, don’t work at all even after I paid .99. Please finish this app or take it down, not fair to take money for this app when it’s absolutely worthless 
even for free.

### 1/5 — It stinks.

*2020-02-12, version 1.2*

You can only write "6" notes!!!!!!!!!! Don't waste your time

### 1/5 — Einfach Mist.

*2018-09-04, version 1.2*

Alles was ich in das Notizbuch geschrieben hatte,war nächsten Tag alles weg.Um es gebrauchen zu können,müsste man es bezahlen,um die Schriftgrösse zu benutzen.

### 1/5 — Horrible

*2018-08-18, version 1.2*

It has no features
