With Logster you can simply create notes for your productions. These "logs" are related to a timecode. For creating logs you can use either buttons or a comment field for individual text notes. Logster further allows you to create logs having a start- and a end timecode to describe time ranges. +++ Internal system clock or external timecode sources Logster can be synced with the internal system clock or an external LTC timecode by simply connecting the timecode source with the audio jack of your iPad. +++ External keyboard support Logster allows a faster input of the commentfield with the support of CMD+RETURN Hotkey while working with an external keyboard. +++ Use of different frame rates All logs are stored as a timecode value, which can be visualized and used with different frame rates (24, 25 or 30 FPS). +++ Customize productions To perfectly fit your needs Logster is highly customizable and lets you create multiple setups for different productions. Each setup may have multiple pages with multiple buttons or input fields. Each keyword can be customized for color and type. +++ Export and email reports Logster works without a permanent internet connection. All logs are saved locally on your iPad and can be sent by email once a mail account is available. You can choose between a CSV file format which may be used in common spreadsheet software or a XML file format while exporting your logs. +++ Collaboration & Workflow integration Logster is designed for single use and also for collaboration. Some productions may require all logged information to be consistent and further be connected to a central database or a content management system. With Logster logs created on different iPads can easily be synced manually or automatically to a central place. If you're wondering how Logster can be integrated into your workflow, we will be pleased to further advise you.

Simplify. Centralize. Customize. EMAT Field Auditor allows you to conduct energy audits of commercial and residential buildings as quickly, easily and efficiently as possible. If you’re an energy auditor, you know how important it is to get in and out of a building as quickly as possible with all the information you need, so you can spend your time on your project or audit report instead of walking through buildings. EMAT Field Auditor is designed to help you do exactly that. With EMAT Field Auditor, you can quickly swipe and tap your way through a building, efficiently and smoothly taking photos and capturing data as you go. While you’re doing that, Field Auditor is sending your data to the cloud, organizing it, and preparing it for review and export to your analysis and reporting systems. Conduct different types of audits? ASHRAE Level I, Level II, lighting, commercial, residential, equipment specific? No problem. With Field Auditor, you can create custom data fields and an unlimited number of customized templates for all the audit types you need. Using Field Auditor is easy. You can setup your client, installation, building and areas back at the office, or right at the site. Select your audit template, and get right to work. EMAT is already set up to capture data on lighting, HVAC systems, building envelope and more. But again, you can customize it with any additional fields you need. As you go through the building, photos are automatically tagged to the area or equipment and those relationships are preserved, saving you tons of time when you’re back at the office. And because the data you collect is synched to the cloud as you go, associates and other team members can review the data as you go, from wherever they are, helping to ensure that you never have to go back to a site to get missed data. Need some help with Field Auditor while you’re out in the field or back at the office? Again, no problem. EMAT Field Auditor is backed by a team of energy engineers and auditors.
