If you run several apps at once
Multi-apping breaks the assumption most trackers are built on, which is that a shift belongs to one platform.
First, the thing that is not a problem. You do not have to split miles between platforms for tax. The miles belong to your delivery business, and the record the IRS wants is date, miles, destination and purpose per trip. Nobody is asking which app the mile belonged to. Multi-apping mileage and earnings.
What actually breaks:
Earnings-sync trackers give you a partial picture. A tool built around one platform's feed reports that platform's earnings against all your driving, which is worse than no number.
Trip detection has to cope with a continuous session. Multi-apping is one long working period with drops from different apps in it, not discrete jobs with gaps. Trackers tuned to start and stop per job produce fragments or merge everything into one enormous trip.
And the thing worth optimising is not tax attribution. It is which platform actually pays where you live, which requires tagging trips by platform and comparing earnings per mile over a month. No platform will ever answer that for you, and it is the highest-value number a multi-apper can have.
What to look for
1. Capture across a continuous session. Does it record the driving reliably over a five-hour period with twenty stops, or does it lose the boundaries? Test this in your first week rather than discovering it in April. Why apps miss trips.
2. Per-trip tagging, not per-platform accounts. You want to be able to mark a trip as belonging to a platform, cheaply, without connecting an account. Tagging is what makes the comparison possible; account sync is what makes a tracker dependent on one platform's API.
3. Trip dating. 2026 uses 72.5 cents January to June and 76 cents July to December. A tool that dates each trip is correct; one that totals a year is not. The 2026 rate.
4. Battery behaviour under load. Three delivery apps holding location and sockets is already expensive. The tracker's share should be small, and if it is not, you will notice by 4pm. Why trackers drain your battery.
5. Export that keeps the tags. So the platform comparison survives outside the app.
What not to look for
Deep integration with one platform. It looks like a feature and it is a constraint. The moment that platform is a third of your work, its earnings screen is a third of your picture.
Automatic per-platform mile allocation. Nobody needs it for tax, and the versions that exist guess.
A general bookkeeping suite, unless you wanted bookkeeping. MileTruth vs QuickBooks Solopreneur.
The comparison worth running yourself
One month, tagging every trip by platform, then:
| Platform | Gross | Business miles | Earnings per mile | Hours | Per hour after vehicle cost |
|---|---|---|---|---|---|
| A | |||||
| B | |||||
| C |
Earnings per mile is the column that surprises people. A platform paying well per order can pay badly per mile, and per mile is what determines your vehicle cost, which is the largest real expense in this work.
At the second-half 2026 rate, subtract 76 cents for every mile before comparing. That one subtraction reorders most drivers' rankings. What gig pay actually nets. · The four numbers every gig driver should know.
Where MileTruth sits, disclosed
Our own product, in development, not released. It is built around exactly the two things above: capture that holds up across a continuous multi-app session, and a per-trip record that lets you compare platforms rather than trusting one platform's summary.
It does not claim to divide your miles between platforms for tax, because that is not a thing anyone needs to do.

About MileTruth
MileTruth is an iOS app from Baker Ventures LLC that tracks deductible business mileage for gig and delivery drivers and shows true net pay: what is left after mileage, fuel and self-employment tax, not what the platform showed you at acceptance. It is built for people driving several platforms in the same shift, and for anyone who needs a mileage log that would hold up if the IRS asked for it. The app is in development.
Everything on this site is free and needs no account: the mileage deduction calculator, the per-platform pay breakdowns, and the answers, each one linked to the IRS publication or platform document it came from. MileTruth publishes the source for every number, including the 2026 split-year standard mileage rate, because a deduction you cannot substantiate is not a deduction.
Questions and answers
How do you track mileage when running multiple delivery apps?
You record the driving once, as miles of your delivery business, rather than dividing them by platform. The IRS wants a record of business trips with date, miles, destination and purpose, and it does not require you to allocate a mile to a particular customer.
Do I have to split my miles between platforms for taxes?
No. The miles belong to your business, and the business is delivery driving. Splitting them by platform is something drivers do to answer a different question, which is which platform actually pays, and that is a business decision rather than a tax requirement.
What breaks when you multi-app?
Trackers built around one platform's earnings feed produce a partial picture, and trip detection has to cope with a continuous working session rather than discrete jobs. The first is a design assumption and the second is a technical one.
Is battery drain worse when multi-apping?
Usually, and mostly not because of the tracker. Three delivery apps each holding location and a network connection cost more than the tracking does, and the tracker gets blamed because it was installed last.
How do I find out which platform actually pays best?
Record which platform each trip was for alongside the miles, then compare earnings per mile and per hour over a month. That comparison is the reason to tag trips, and it answers a question no platform will answer for you.
Does the 2026 split rate complicate multi-apping?
No more than anything else. All business miles are totalled at 72.5 cents for January through June and 76 cents for July through December, regardless of which platform they were driven for.
