Build Mode vs RescueTime: Time Tracking Without Cloud Surveillance

Before Build Mode existed, I tried the trackers that were already out there. Every single one wanted me to create an account before it would tell me where my own time went. The data was about me, generated on my machine, and step one was handing it to a server.

RescueTime is the best known of the automatic trackers, and I'll say up front that it's good at its job. It watches your day, scores it, and hands you a report you never had to think about.

I wanted something narrower. I was building a startup, and for a long stretch my hours were the only visible progress. No users, no revenue, just hours. I didn't want my day rated. I wanted proof the hours existed. Build Mode is the tool I built to get that proof, which is why the two apps come out shaped so differently.

Build Mode and RescueTime, side by side

What RescueTime records, and what Build Mode can see

RescueTime runs continuously in the background, logging the apps, websites, and documents you use to calculate productivity scores. That record syncs to its cloud, which is what makes its cross-device reports possible. None of this is hidden. It's the product working as designed, and the RescueTime comparison page lays the two approaches out in full.

Build Mode can see one thing: the name of the frontmost app, and only while a session is running. It never records browser history, keystrokes, window titles, or screenshots.

Here's the part I'm genuinely proud of. The app contains no networking code at all. You can search the binary for networking symbols and you will find none, because there is nothing in it that can transmit. Your reading and your codebase stay private by structure, not by policy.

Sessions you start, not a day that gets scored

Build Mode records nothing until you press ⌘⌥B. You press it when the real work begins and press it again when you stop, so the record you build contains only hours you chose to count. When you step away, the session pauses on its own, and the totals stay honest.

I still use it this way every day. While a session runs there's a small clock in the MacBook notch, and at the end of the week I open Wrapped and look at where the hours went. The work adds up somewhere I can actually see it. That was the whole point.

What I refused to build

There are no timesheets in Build Mode, no invoicing, no teams, and no cloud. That was a decision, not a gap. Every one of those features drags an account and a server back into the product, and the account was the thing I was trying to get away from in the first place.

It also changes how you pay. RescueTime's paid plans are subscriptions, billed monthly or annually, for as long as you keep tracking. Build Mode is a one-time purchase: pay once and it's yours. There are real paying customers now, so apparently I wasn't the only one who wanted the smaller thing.

If RescueTime fits you better, use RescueTime

I mean that. If you want a hands-off record of your entire day and you're comfortable with that record living in a cloud, RescueTime has offered exactly that for years, and it does it well.

If you want to count the focused hours you choose, on your own Mac, with nothing leaving the machine, that's the shape Build Mode was built in.

Get Build Mode for Mac. You pay once and that's it.
