InerTrak for iPhone and iPad, based on the award-winning desktop InerTrak, is a time-tracking tool for designers, contract workers, lawyers, or anyone who works on multiple projects on an hourly basis. It automatically keeps track of the time you spend on different projects thorughout the day; all you do is click to start and stop the timer. The iPad version makes full use of the large screen. You can create a list of clients, each with an optional hourly rate. Each project is associated with a client, and includes an hourly rate (either set automatically from the client's rate, or set individually) which is used to automatically calculate the monetary value of time worked. A detail view of each project shows the daily totals of both time and money, with the ability to check off days as they are billed. Dates are automatically added when you start the timer, but can also be manually added, if necessary. Time values can be edited, if needed. Projects can be marked as completed and optionally sorted to the end of the list to get completed projects out of the way of active projects. A summary view shows the totals of each project -- the total time and money, billed time and money, and unbilled time and money. You can see a summary for any desired time period. Time values can be displayed in a variety of formats: hours minutes and seconds; hours and tenths of an hour; hours and sixths of an hour; hours and quarters of an hour; even hours and hundredths of an hour. You can create an email message containing the InerTrak data in CSV format. Send it to yourself and then, on your computer, copy and paste the data into Excel or any program that understands CSV format. You can add a note or comment to any date. The currency symbol can be customized to any one or two characters that you want. InerTrak for iPhone and iPad is fully integrated with InerTrak for the desktop. You can use InerTrak on your iPhone to keep track of time worked in the field or when away from your desk. Then, with a couple of button clicks, copy that data to the desktop InerTrak and take advantage of more advanced reporting capabilities, print timecards or invoices, etc. Important: Data synchronizing requires a wireless network accessible by both your iPhone/iPad and your desktop/laptop computer running InerTrak (version 3.4 or higher). If you don't have the desktop InerTrak, you can try it free for 30 days. Download it from www.inertron.com/inertrak. What InerTrak does NOT have: o It has only two levels of terms, Client and Project. It does not allow you to further break down a Project into sub-projects or tasks. o The granularity of time is a day; it keeps track of the total time that you spend on any Project on each day. It does NOT keep track of the individual times that you start and stop the timer throughout the day. If you need either of the above features, then InerTrak is not the right product for you. There is a detailed user's guide online at: www.inertron.com/mobile/inertrak. The user's guide describes all the features in InerTrak. If there is a feature or capability that you need that is not described there, InerTrak is probably not the right product for you. Feel free, however, to email us and request it; the best way for us to make the product better is to know what people think is missing.

Crashes when attempting to start it. Developer does not answer emails. Too bad. ### 1/5 — No customer service, is this company out of business? *2023-01-03, version 2.3.11* Can’t reach anyone to get help with INERTRON products. I’ve used their software for years and liked it, but now it’s not working and I can’t get help. I think the developer is no longer supporting these products, too bad. ### 4/5 — Get rid of Scrolling feature *2020-06-09, version 2.3.9* Good program that is slowed by scrolling feature. Get rid of it and make data entry quicker. ### 4/5 — Very good time tracker *2014-11-06, version 2.3.8* I have been using this, along with the desktop version for about 4 years. It does a great job keeping track of time and billing of my clients for iOS projects. ### 1/5 — Inertrak *2013-11-18, version 2.3.4* I have just upgraded the iPad Air, and this will not now display properly. Used on iPhone for a long time with few issues. Installed to iPad today, terminates after EVERY new client added It's so inconvenient (i was going to say rubbish) that I am unable to proceed further with this app on the iPad (which is for work, the iPhone is personal) ### 4/5 — A great all-around app! *2012-10-26, version 2.3.3* iOS 6 brought a few hiccups to this app, but now that they have been resolved in this new release, I'm happy to report that the app is once again a pleasure to use. ### 5/5 — Awesome tool with awesome support *2012-10-19, version 2.3.3* InerTrak is an amazingly useful app that I use all day long in my consulting business. It is worth every penny and is easily the most usable and used app on my iPhone. Beyond the great features, the support from InerTron software is exceptional. I encountered a rather obscure bug which I emailed InerTron about. Within an hour I received an email reply and we began a discussion about the bug. InerTron could never reproduce the bug on their end, but that didn't stop them from researching the code until they found a potential defect which they immediately worked to fix. I highly recommend this iPhone app as well as the desktop based version available on their website.

One thing though ... it crashes a lot. Nevertheless, I like it so much I'm going to keep an eye open for bug fixes. Michael ### 3/5 — Love it! Needs small tweaks. *2012-04-18, version 2.3.2* This app does a FANTASTIC job keeping up with my time spent with various clients and activities. I started using it a couple of days ago, and continued to use another. The only drawback I see so far is the lack of " reports". Other project tracking type apps I have used, allow for a quick report of each project or client. Without this addition, to use this app, I would have to deal with each bit of data in this app, then another. With this addition, it would be a 5 star app that I would pay 5 times higher price for. ### 5/5 — Best App on my phone *2012-04-14, version 2.3.2* Saves time and hassle trying to remember starts and stops, materials. Very easy to use for the busy worker. Just hit the stopwatch when you start, add any expenses as you go, then hit the stopwatch when you leave. Finish by looking up summery and it's all done for you labour, materials and total bill I have used this app for a year now and would be lost without it ## Frequently asked questions about InerTrak ### What does InerTrak do?
