Data Transfer Calculator is designed to accurately calculate the time required to transfer files from disk to disk or across networks. Enter the amount of data — the transfer rate — and Data Transfer Calculator will automatically calculate the transfer time. Choose between Base 2 and Base 10 units to ensure accurate results specific to your operating system. Tap the result to toggle through different time units from seconds to days. Timers allow you to track transfers even when you’re not at your computer. Timers are compatible with Notification Center — which means the app does not need to be on-screen to receive a notification. Set multiple timers to track additional transfers. The Info page reveals the logic behind the app and clarifies any mysteries between bit and byte. ## Key features - Calculate transfer time - Input data amount and transfer rate - Base 2 and Base 10 unit options - Toggle time units (seconds to days) - Set multiple timers - Notification Center compatibility ## Recent user reviews (8 of 8) All indexed reviews: https://appshunter.io/ios/app/data-transfer-calculator/id691674678/reviews.md ### 2/5 — Good app but missing features *2022-06-27* The app is really easy to use and has a nice simple look to it - it’s missing some features in my opinion - Being able to edit the timer you created - The ability to see the details of the timer data size/transfer rate so you know which one to use - when creating a timer being able to name it before coming out of that ui - when on the Home Screen clicking on the name to rename it if you don’t want to the ui keeps popping up until you put a name in it - when you have a few timers be nice if you could organise them yourself rather them populate as and when you create a timer - hope the developers could sort these thing out ### 1/5 — More transfer rate units *2018-01-17* In your help file you clearly state the difference between a bit (b) and byte (B) but don’t provide transfer rates that include bits-per-second speeds. Meaning...I have to open a calculator to use this calculator. Dumb. ### 4/5 — Great tool. I second adding additional speeds. *2016-09-19* This is a great tool. I would give it 5 stars if the tool could support the selection of mbps speeds and allow for saving of presets so you don't have to choose all the options all over again. Great job on a great tool. ### 3/5 — Looks great and easy to use, lacking data transfer speeds *2016-02-19* Totally appreciate the clean look and feel. Please add more data transfer speeds though, lots of free web pages that provide this info but I'd prefer if it were in this easy to access application so I didn't have to Google search every time I need to know how long a transfer will take. Thank you for the app so far, very useful. ### 5/5 — Great simple app *2015-05-11* This is exactly what I came looking for. It's way easier than trying to do the conversion myself on a normal calc or going to the data transfer calc website to do it. Makes me look smart in front of my client since I am able to do the calculation so fast. Must have for network admin :-) ### 4/5 — Awesome *2013-12-19* Has two things that are confusing but it can be finagled to do what you want even if the options are incorrect. Very nice to have. If they could add higher transfer rates, that would be great. ### 5/5 — Awesome! *2013-12-11* Exactly what I was looking for! I can't tell you how many times I've searched in Google for "data transfer calculator" to only go to the same website over and over. This app saves me that time. Wonderful. Would love if all the UI elements were updated for iOS 7 tho. But from a usability standpoint it's perfect. ### 5/5 — Great Utility *2013-08-28* Awesome! Perfect for calculating uploads and transfer times for video footage. The built in timer is a great bonus. ## Frequently asked questions about Data Transfer Calculator ### What is the price of Data Transfer Calculator?
