How Shiftly works

1. The big picture

Once you link your Rivian, Shiftly watches your vehicle’s live data — gear, odometer, and location — in the cloud. From that it builds two things:

• Trips — a driving session, made up of one or more drives. A trip is what you see as a single entry on the Trips tab.
• Reports — weekly and monthly summaries that split your miles into business and personal, generated automatically on a schedule.

Everything is automatic. You don’t press start or stop; your only job is to tag each drive as business or personal so the right miles count toward your deduction.

2. Trips: your driving sessions

A trip is one driving session. It groups together all the driving you do between longer stops — for example, a full evening of rideshare runs, or a day of visiting clients, is usually one trip made of several drives.

When a trip starts

A trip begins the moment your Rivian shifts into Drive or Reverse while no trip is already in progress — wherever you are, at home or anywhere else. There’s nothing to tap. While a trip is open, you’ll see a “Trip in progress” banner on the Trips tab.

Each vehicle has its own trips, so if you drive more than one connected Rivian you can have more than one trip going at the same time.

3. When a trip ends on its own

Shiftly closes a trip automatically once you’ve clearly stopped driving:

• Parked at home for ~30 minutes. When the car is at your home location and stays parked for about half an hour, the trip is closed.
• Parked anywhere for ~5 hours. Away from home, Shiftly waits longer before deciding the session is over — so a long shift with meal breaks stays one trip, while an overnight stop ends it.

A trip’s end time is set to when you actually parked, not when Shiftly noticed. If the car was asleep and we only catch up later (or after a reconnect), the trip is still recorded as ending at the real park time, so durations stay honest.

Trips that aren’t saved

Sessions under about half a mile are discarded — nudging the car around the driveway isn’t a trip. As a safety check against odometer glitches, a single trip is also capped at 1,000 miles.

When a trip closes, Shiftly sends you a “ready to tag” notification (if you’ve enabled notifications) so you can label its drives.

4. Ending a trip yourself

You don’t have to wait for the automatic close. There are two ways to end a trip yourself:

“End trip” — finish now, keep tracking on

Tap the “Trip in progress” banner and choose End trip. This finalizes the current trip right away so you can tag it immediately, instead of waiting for it to close on its own. Tracking stays on, and your next drive starts a fresh trip.

• Park first. You can only end a trip once the car is parked. If you’re still moving, Shiftly asks you to park before ending — finishing mid-drive would record an incomplete trip.
• Any distance is kept. When you end a trip yourself, it’s saved no matter how short — even a 0.1-mile errand — because you intentionally recorded it.

“Stop data collection” — finish now, and pause tracking

In Settings, turning off data collection for a vehicle also closes the trip in progress, then stops tracking that vehicle until you switch it back on. Any qualifying trip is saved and ready to tag. Use this when you want privacy or a break from tracking; see the Privacy Policy for what stopping collection means for your data.

5. Drives inside a trip

A trip is split into one or more drives — the individual legs of your session. Drives are what you tag as business or personal.

How a trip gets split into drives:

• A short stop (under 10 minutes) keeps you in the same drive — a quick drop-off, a red light, or grabbing coffee doesn’t start a new leg.
• A longer stop (10 minutes or more) ends the current drive. The next time you pull away, a new drive begins within the same trip.

So a single rideshare evening might be one trip containing a dozen drives — one per passenger leg — which lets you tag each leg independently.

6. How miles are measured

Mileage comes straight from your Rivian’s odometer, not from estimating GPS points. Each drive’s distance is simply the odometer reading where it ended minus where it started, and a trip’s total is measured the same way across the whole session.

Because it’s the real odometer, the number matches your car exactly and holds up if you’re ever audited. Readings that don’t make sense — a negative distance, or more than 1,000 miles — are treated as glitches and dropped rather than saved.

7. Tagging: business vs. personal

Tagging is the one thing Shiftly needs from you. Each drive is labeled either:

• Business — counts toward your mileage deduction.
• Personal — kept separate and excluded from the deduction.

Until you label it, a drive is Untagged. Open a trip from the Trips tab to tag each drive, or use All Business / All Personal to label every drive in that trip at once. You can also tag straight from a report’s “needs tagging” list, and you can re-tag a drive any time.

Tagging updates your reports immediately: the affected week’s business/personal split refreshes on the spot, and a monthly report that was only waiting on that drive becomes available right away — no need to wait for the next scheduled run.

8. Weekly reports

A weekly report summarizes a single week (Monday through Sunday) for each vehicle, splitting its miles into Business, Personal, and Untagged.

• When it’s created: automatically every Monday at about 3:00 AM Central Time, covering the previous week that just ended.
• What it needs: at least one completed trip for that vehicle during the week. A weekly report is created even if some drives are still untagged — those miles simply show up in the Untagged bucket until you label them.
• Staying current: when you tag a drive from a past week, that week’s report recalculates immediately, moving miles out of Untagged and into Business or Personal.

Because a week’s report is created after the week ends, the current in-progress week doesn’t have a weekly report yet — it appears the following Monday.

9. Monthly reports

A monthly report summarizes a full calendar month per vehicle. Unlike weekly reports, a monthly report is only finalized once every drive in that month is tagged — it’s meant to be a clean, complete record.

• The month has to be over. On the 1st of each month (~3:00 AM Central), Shiftly lines up the month that just ended as a report to complete.
• It completes once fully tagged. A background pass runs every day at about 4:00 AM Central and finalizes any past month whose drives are now all tagged. Until then, the month shows as “needs tagging” with a count of the drives still to label.
• Tagging the last drive finishes it instantly. When you tag the final untagged drive of a past month, its report becomes available right away — you don’t have to wait for the 4:00 AM pass.

10. Why a report hasn’t appeared

If you’re expecting a report and don’t see it, here’s why:

Weekly

• The week isn’t over. The current week’s report is created the following Monday morning.
• No completed trips that week. If the vehicle had no qualifying trips (or only sub-half-mile moves that weren’t saved), there’s nothing to report.
• A trip is still in progress. Only completed trips are counted; an open trip is included once it closes.

Monthly

• The month hasn’t ended yet. Monthly reports are only built for months that are over.
• Some drives are still untagged. This is the most common reason — a monthly report waits until every drive that month is labeled. Tag the remaining drives and it appears immediately. Look for the “needs tagging” indicator on the month.

11. Dates, weeks & time zones

Shiftly groups your driving by calendar day, week, and month so a late-night drive counts on the day you actually drove it. Reports are currently bucketed in Central Time (America/Chicago), and the scheduled times above (3:00 AM, 4:00 AM) are in that zone. This means a drive just before or after midnight is attributed to the Central-Time calendar day it falls on.

12. Turning tracking on and off

Tracking is controlled per vehicle in Settings. Turn it on once and Shiftly collects from your Rivian in the background — even when the app is closed — with nothing running on your phone and no phone GPS or battery drain.

Turn it off any time for privacy; that ends the current trip and pauses collection for that vehicle until you turn it back on. You can also delete your account and all associated data whenever you choose. For the full details on what’s collected and how it’s protected, see the Privacy Policy.

13. Tax-time export

Today, your weekly and monthly reports keep a running, tagged record of your business miles all year. A downloadable, IRS-ready annual report — formatted for the standard mileage deduction so you can hand it to your accountant or tax software — is on the way.
