Our biggest fans are consultants, attorneys and contractors. Time Master is used by individuals working independently, to attorneys from some of the biggest law firms in the USA. If you need to keep track of time and expenses, you can’t find a better app than Time Master. We at On-Core are IT professionals, so we have firsthand experience with billing and keeping track of time. We know from personal experience what is needed and have made this app so flexible, it works for virtually anyone in any industry in which time needs to be kept.

OPTIONAL MODULES (one-time additional fee required as an "In App Purchase"):
- Invoicing: If you want to do billing directly from your iPhone or iPod Touch then look no further. The most powerful invoicing module built directly into Time Master. Professional PDF invoices can be emailed to the client, including your own logo.
- Quickbooks Export: Easily export your Time Entries with a QB IIF file. Win QB 2007 Pro or greater. Mac QB 2010+ with our TimeBridge app (fee applies). See site before purchase.
- Synchronization: Wirelessly synchronize two or more devices. If you have an iPad and an iPhone and want to keep the data synchronized between the two devices, this is for you!

Time Master can track both time and expenses. You can track time using start and stop times, duration, and/or timers. All time entries are tracked for a single day, so time entries cannot be greater than 24 hours. It will allow you to time across days, for example if you start a job at 8 p.m. and finish at 2 a.m., it will have a duration of 6 hours.

Expenses can be setup for recurring fixed cost items, such as burning a CD, reimbursement of hardware items, or fluid things such as toll expenses, automobile mileage, etc.

Quick reporting can be done on the iPhone / iPod Touch with the Reports function. The report can be emailed in an HTML and/or CSV format.

Adding new Clients, Projects, Tasks and Expenditures is super easy.  You can create them on the fly without having to navigate to a separate maintenance screen. To edit them you can tap on Setup, do you edit and then return to where you left off in Time Entries or Expenses. By selecting a Project or Task first will automatically fill in the Client field for quick entry.

We’ve made everything as seamless as possible, as you would expect from a top class iOS application. Please click on the "On-Core website" link below to download the documentation on your computer.

Very Helpful App!

As a gig worker, I have multiple clients with different projects and phases, and different bill rates. Time Master has the ability to handle it all. Frequently, I need to add notes about the specific task I am on, and there is a place for that, too. At the end of the month, I export my hours as a PDF time sheet or as a CDF to import into an Excel worksheet and attach it to my invoice, or if the client has no required format for my invoice, I can generate the invoice directly from Time Master. It backs up to Dropbox and keeps an ongoing (revisable) record of everything I have done for as long as I need to maintain the record. It is a great program that I have used every work day for many years!

Excellent but may not be for everybody

I have relied upon this app for years, and it's worked consistently. Also, contrary to some comments, I really don't think this becoming "a windows app" or the world has "moved on". I'd say for sure that the app doesn't attempt to be the whiz-bang UI experience that the ideal iOS app needs to be to "feel right" to every Apple user. I'm a huge Apple user, have nothing but macs, iPhones, Apple Watch etc.... and yet, every time I've tried to find an app that "supports the whole Apple experience" the app itself, in practical terms, falls short.

I'd say if you are causually looking for something to track time, and do so in the "Apple Way" this may not be the best app for you. However, if you are a professional with many clients, different types of jobs, different billing rates and need to reliably and consistently track time, send invoices, assure your data is backed up and available... I have NEVER seen anything that can compare with this.

Bottom line: Practical, reliable app from a developer that seems to keep updating and assuring it works. The only downside: A bit of an Apple "meh" experience if you're looking for warm "Appleness". I can live with that.

Great Billing App for Attorneys

As an attorney I have some clients with several different matters. This separates them easily and keeps an ongoing total of billable hours for the month. It is simple to use and can break down time into 6 minute intervals (although it does not use the .1 denomination, which would be preferable. I would love even more if this were made an option). Great for keeping accurate billing on the fly so that nothing slips through the cracks. I have tried several other billing programs and this is by far the best for the legal profession.
