Yes to the desktop, no to the mobile

I appreciate everything this program has done for me. The four star is for the entire program as a whole, however the same cannot be said for the mobile programs. For one there isn’t an app that includes all of them in one thing, and for some reason they had a feature that includes novels which is only shown in the “desktop” version but seldom mentioned in the mobile program. Some controls for it can be finicky and can get you into some trouble if you’re not careful enough. Worst of all if you’re not careful with this, you could lose a significant amount of progress in a short amount of time. I feel like that these apps are poorly managed as they are not properly adapted to the latest version seen in the “desktop” variation. Don’t get me wrong, I really love this program, this has gotten me through high school and into a lot of things including a self publishing business using Celtx as a whole. If you love Celtx as a whole too, you’re better off saving the painful hassles by just getting a laptop fitted for Celtx.

Best Screenwriting Software, Ok Mobile App

There is no better screenwriting software that I’ve tried and I’ve tried a lot. It’s great being able to edit from any device because it’s all stored on the cloud. The formatting is intuitive and professional-grade. Very trustworthy.

The mobile app, on the other hand, has some issues. Sometimes the cursor returns to page 1 without reason, forcing you to find where you’d just been working a moment ago. Sometimes notes pop up unprompted and the button to dismiss is only available if you turn your phone to landscape. The basic qualities are fine, but many of these types of bugs need fixing for a 5-star rating.

One thing that should be easy to fix: edit title page on mobile. Currently I can’t figure a way to do it. Would be nice and seems like it ought to be an easy fix.

Amazing if Used Extensively

I work productively on a whim. One day, I decided to write a short film script, so here I am. I downloaded this program because I didn’t want to use typical Microsoft Word, plus I wanted a separate program for this writing and ability to access my writing on both my phone and my computer. Starting on the computer, the program Celtx provides educational “starter courses” , which really helped me start the writing and understand just what I needed to do. Downloading the mobile app was necessary for on-the-go writing, and I’m glad I did, honestly. Using this program I’m able to keep track of my writing and write whenever I want :). My only complaint is the occasional difficulty to open my writing without internet access, but this happens with all WiFi-enabled programs. Definitely would recommend to anyone thinking about writing a script or otherwise.
