The Freedom Tube Bias Calculator (FTBC) is definitely not your average tube bias calculator app. It has been designed to give you the freedom to set it and use it the way you want to. Freedom is the keyword here. Preview version (free)- You have the freedom to try it before you buy it. Download the app for free and you instantly have the Preview version. The Preview version gives you access to any of the apps views so you can check the functionality out, get the hang of the user interface and decide if this app may be useful to you and which options you might like to buy. Everything is functional except for the Calculate button. Basic version (In-App Purchase)- Buy the Basic version within the app and you will get the core functionality.- There are two calculation modes so you can calculate either the Bias % or the Plate Current at any given moment.- More than 40 available tube types to choose from and you still have the freedom to manually put your own Maximum Plate Dissipation value if you want to. Preset option (In-App Purchase, optional)- Edit, manage and save your custom presets in the Preset view and directly retrieve them on demand from the FTBC view.- Make the application fill the respective fields with your chosen presets values automatically, every time the app starts.- By buying this option you get 10 presets. If you buy the Settings option as well you will get 20 presets in total. Settings option (In-App Purchase, optional)- Make the Bias field change color (blue, green or red) depending on your Biasing Type/Class selection and the respective thresholds.- Set your own thresholds to define the safe/optimal bias range per Class/Biasing Type combination.- Make the application start on the calculation mode, class and biasing type of your choice.- Get notified when the Plate Voltage value you put in the respective field of FTBC view exceeds the maximum safe operating voltage of the tube type you have chosen. Key features for all versions and options:- All values are selected using pickers throughout the app (no virtual keyboards unless you want to edit a Preset name in the Preset view).- Even if you own a device with a relatively small screen and the picker covers up a significant part of it, you will always know which field you are currently editing thanks to the indicator at top of the view.- Works in both portrait and landscape orientations on iPads (on iPhones its limited to portrait orientation only, for practical reasons).- FTBC is and will always be Ad-free.- No Internet connection is needed unless you want to buy (In-App Purchases) or get some information about a product.- Sound notifications (you can enable or disable each of them) - Vibration notification (available only on iPhones, you can enable or disable each of them)- Option to disable the background images- Option to disable some of the animations- You can watch videos that walk you through the apps functionalities and features here: https://www.youtube.com/playlist?list=PL96o_7fAUNwUovEhKhxERTNYJGS9YF2JbIf you have any questions, suggestions, problems or feedback, dont hesitate to contact me at FreedomTubeBiasCalculator@gmail.com (please make sure FTBC is included in the subject of the email, preferably at the beginning).
