1. Add a Drive by Hand

   On the "Drives" tab, tap the plus button in the top right, then choose "Add a Drive". (The same menu offers "Track a Drive" if you want to record a live drive with GPS instead.) Set the "Start" date and time, then tap "From" and "To" to search your saved places or an address. Enter the "Distance" and, if you like, the "Duration" in minutes. Pick a "Category" and add a "Business purpose". The IRS asks for a purpose on every business drive, so "Save" stays off for a business drive until you've added one, unless you've turned purpose reminders off in Settings. Tap "Save drive" to finish, or "Save and add another" to keep the form open. That second option keeps the date, category, and vehicle filled in, which makes back-filling a week of drives quick.

2. Let MileMarker Fill In the Distance

   Once "From" and "To" both have text, a "Look up driving distance" button appears under the form. Tap it and MileMarker asks Apple Maps for the driving route between the two points, then fills in "Distance" for you. You can still change the number afterward. Both this lookup and the "From" and "To" address search send what you type to Apple Maps, and only when you use them. If no driving route exists, you'll get a straight-line estimate instead, and the form tells you so. Pick a deductible category like Business and the form previews the deduction, valued at the IRS rate in effect the day you drove, even for back-dated drives.

3. Edit a Drive's Details

   Tap any drive in the list to open it. From there you can reclassify it with the category control, tap "Business purpose" to add or change the purpose, tap "Job" to assign a job (Jobs are a Pro feature), and tap "Tolls" or "Parking" to record those expenses. Every change is recorded in the drive's edit history, so your records stay audit-ready.

4. Edit the Start and End

   On the drive's screen, tap the pencil button next to the drive's title to open the "Start & End" editor. Tap "Start" or "End", then search by "Place name or address". You can pick a saved place, pick an address result, or keep exactly what you typed. On drives with a recorded route, moving an endpoint to a new position recalculates the drive's distance, so the mileage stays honest.

5. Log the Return Drive

   If automatic tracking or a manual entry only caught one direction, open the drive and tap "Add return drive". The "Add Return Drive" sheet asks when you "Departed", starting from the outbound drive's end time. Set it to when you actually left, then tap "Add". MileMarker creates a new drive back with the start and end swapped and the same distance, and it inherits the category, purpose, vehicle, and job so you can reclassify it on its own if the drive back served a different purpose.

6. Split One Drive Into Two

   Sometimes automatic tracking records two stops as one drive, like a client visit plus the drive home. Open the drive and tap "Split drive". In the "Split Drive" sheet, drag the slider to move the split point to where one drive ended and the next began. The "First leg" and "Second leg" cards preview each new drive's distance and times. When it looks right, tap "Split into two drives". Tolls, parking, and attached receipts stay with the first leg so nothing gets double-counted, and both legs keep the original category and purpose so you only need to reclassify the leg that changed.

7. Merge Drives Into One

   If one errand got recorded as several short drives, touch and hold a drive in the list to enter select mode with that drive picked, or tap the checklist button beside the search field (it's labeled "Select Drives" for VoiceOver). Tap the other drives to select them. With two or more selected, a "Merge" button joins the bar at the bottom. Tap it, then confirm "Merge into one drive". Distances and expenses are added up, the route is joined end to end, and purposes are combined. The category, job, and vehicle carry over only when every selected drive agrees, so a mix of business and unclassified drives merges to unclassified rather than quietly inflating your deduction. Merging works within a single tax year, and it removes the original drives, so review the selection before you confirm. The same selection bar also offers "Classify" and "Job" for bulk changes.

8. Delete a Drive

   Open the drive and tap "Delete drive", then confirm on the "Delete this drive?" dialog. To delete several at once, enter select mode, pick the drives, and tap "Delete" in the bottom bar. Deleting is permanent and removes the drive's mileage from your totals. Drives in a locked tax year show a lock instead of a checkbox in select mode and are skipped by bulk delete.

9. Name Frequent Places

   On a drive with a recorded route, tap "Name start place" or "Name end place" above the title. These pills only appear when that spot isn't already covered by a saved place. Give the place a name like Home or Client A and tap "Done". The drive's label updates right away, and future drives that start or end within the place's radius get labeled automatically. You can also manage places in "Settings" under "Drives & Data" then "Named Places", where "Add place" lets you build one from an address search or by choosing a point on the map. Named places also power auto-classify rules, which are a Pro feature.
