## What is FidoLED?

FidoLED is a LED Screen calculator. Dial up the manufacturer, the model and then enter the size you want in Modules (tiles), Pixels, Metres, MM, Inches or feet and it will return to you the number of pixels for the given screen, the width, height and weight of the screen plus the power draw for the screen.

It will also generate a print out of the information as well as generate grids of the led screen in pixels for helping to make pixel mapped content, you can spit out just the actual screen in pixels, or set on a standard video canvas with or without a pixel shift offset, or as a photoshop script file so that you can modify it in photoshop for the more creative screens.

FidoLED was originally written for the PM's and Techs of Creative Technology (CT) the Database is very heavy on CT owned tiles. There is a small CT Logo in a red circle to the right of the make and model selection - to see every tile in the database just tap the CT Logo so that its crossed out and you will see all the tiles in the database, to see only the CT Owned tiles tap the CT logo again and it will filter the database to tiles owned by them

I can add ANY make and model of tile VERY QUICKLY to the database, the majority of the time I am on PST so depending on when a request email is received, turn around time can be very quick and i will email you back when the database has been updated.

Tap on the FidoLED logo on the main page and you will be presented with a form where you can fill in the information asking me to add the LED make and model you want.

As more makes and models are added to the Database I will send a notification message (Push Notification) to let you know the is a database update for the app. If FidoLED is in use at the time it will grab the database automatically, if its not then just select the notification message and it will open FidoLED and update the Database.

You can also manually update to the most current Database by taping on the Database Update button on the bottom left of the main screen (the second icon to the left)

If you have any questions or comments about this application please feel free to email me Darren@fidoLED.com

### 5/5 — One of the most useful work Apps I have

*2022-11-03*

I have been using this for an age - and it’s one of the best tools for helping out content creating colleagues or production types wanting to know weights and power. Well worth the money in what it will save you in time. Darren keeps the database updated regularly and I’ve recommended it to many friends in the industry. TPC

### 1/5 — Doesn’t work

*2021-08-06*

Seems like an awful lot of high reviews for an app that doesn’t function.  Bought on site, loaded, selected screens, crashed.  Myself and two other users.

**Developer response:** Hi there, 

I am sorry for the trouble, I had a bug that slipped in to the app that has now been fixed, if you download the current version it will work fine. Please let me know if you are still having issues with it though.

Thanks

### 5/5 — Must have app for LED

*2021-03-02*

This app is incredibly helpful and a must have for any LED build. It pays for itself many times over per show and I’d gladly put this against any other program out there. 

Thank you so much to the developer for making a good product that works well and integrates seamlessly.

## Version history (last 5 releases)

### 1.2.4 — 2025-07-14

Added a back up Database server for when the main one has fallen over. Also packaged with the latest July 2025 Database as the default database

### 1.2.3 — 2022-12-28

Added in a Keyboard so the make and model can be filtered by its first letter, press * will reset the list to all.

### 1.2.2 — 2022-11-27

V1.2.2 is a maintenance release, iOS doesn't let me download files to permanent storage i.e where the app is stored, so when the app first runs it checks to see if the database is in temporary storage, if its not it copies in the shipped database, this is why sometimes you could swear a product was in the database but it's not there, its because after some undetermined amount of time, when your device needs the space it will clear out the temporary storage and with it the current database you have been using, the app loads again and moves the shipped database across, and you are now using an out of date database. Well now I am forcing a download of the most current database after the app is loaded, if it can grab the latest one you are set, if for some reason it can't it will just move the shipped one to temporary storage. - this has been bugging me for a while, and is probably why I get a lot of repeat asks for products that are already in the database from iOS users, so this should fix that.

### 1.2.1 — 2022-11-02

Added the ability to get a screen size based on the desired Pixel count.
Added in the calculation for the number of ROE 4 and 2 way brackets needed for a screen based on tiles needed.
Updated the database to the most current version.

### 1.1.24 — 2021-08-09
