Marlow vs a shared Google Calendar for a parent's appointments and rides

The shared calendar is the first serious thing most families try, and it’s a good instinct. You make a calendar called “Mom,” share it with your siblings, and start typing in appointments. It costs nothing, it’s on every phone already, and the sharing works with the aunt who would never install an app. When you set up a family on Google, a calendar called Family is created for you, and it works in 44 languages on any device anyone in your family owns.

Everything in this post applies just as much to an iCloud shared calendar. For this job the two are the same category: a calendar of events, shared with named people, with a view only option. Where they differ, the post says which one.

The question is what happens when the calendar is full and the rides still aren’t covered. That’s the gap, and it’s the whole comparison.

Side by side

The calendar column is Google Calendar. Every ride and parent row reads the same for an iCloud shared calendar.

A calendar records events, and a family driving a parent needs to record commitments

“Cardiology, 9:40, Northside” is an event. It’s on the calendar, so it looks handled. Whether somebody is actually taking her there is not something the event can hold, so families invent a way. “DRIVER?” goes in the title. A second color once somebody has agreed. Each of those is a convention maintained by hand, by the one sibling who set the calendar up, and the first week she’s on vacation the convention lapses.

Invitations don’t rescue it. Invite your brother and he answers yes, no or maybe. “Yes” means he’s aware of it. It doesn’t mean he’s driving. “Maybe” means nothing at all, and it’s the answer most people give. Google’s own appointment slots were retired in 2024, and what replaced them is booking the owner’s time, which is the wrong direction for a family: you don’t want Mom booking a slot with her son, you want her son claiming her ride.

Marlow’s entry has the column a calendar doesn’t. Each appointment shows whether it still needs a driver. Orange means nobody yet, green means it’s handled with a name on it. Anyone in the circle claims it with a tap, and the claim is the commitment; there’s no confirm step, on purpose. A round trip is one appointment with two rides, each with its own driver, so the ride home can’t quietly go missing while the ride there looks covered.

So the usual outcome is the calendar for the when and where, and the group chat for the who. The who is the hard part, and the chat can’t hold that answer either.

Who wins? Marlow. This column is the whole reason it exists.

For the when and the where, a calendar is enough

That deserves to be said plainly. Google Calendar and Apple’s shared calendars handle repeating events, an address that opens in a maps app, a color per calendar so Mom’s cardiology sits in green beside your own work meetings, and reminders on every device. The month grid gives you a view of the whole year that Marlow doesn’t try to draw. Google Calendar is in 44 languages. Marlow is in five.

Reach is the bigger point. A shared calendar works on Android, in a browser, on a work laptop and on the aunt’s tablet. Your cousin who does one ride a month can open it without installing anything. Marlow is iPhone today, with the Android app built and in testing, and there’s no web app; everyone who claims rides needs the app on an iPhone.

Marlow does store the real address, opens directions in Apple Maps, Google Maps or Waze, works out a “be ready” time from the measured drive, and on Plus reads an appointment off a photo of the clinic letter. None of that makes it a calendar, and it isn’t trying to be one. Marlow is the column a calendar doesn’t have, plus a screen for her.

It also writes into your calendar rather than replacing it. A ride you claim in Marlow lands in your own Google, Apple or Outlook calendar, with a warning if it clashes with something already there. Nothing goes the other way yet: appointments in your calendar don’t appear in Marlow, and the rest of your parent’s schedule doesn’t mirror into yours. Two way sync is listed under Plus on the pricing page and isn’t built, so a family whose whole week is in one calendar will type some things twice for now. One more thing from Google’s help: a calendar’s sharing settings can only be changed from a computer, so setting up the “Mom” calendar is a laptop job, not a phone job.

For when and where, a calendar is enough. Marlow writes each claimed ride into it and leaves the rest alone.

The invitation isn’t a claim, and “maybe” is the answer most people give

The reason this matters is who’s doing the driving. Most caregivers are helping with transportation, and most of them don’t live with the person they’re driving. The rides are spread across siblings in different towns, each with a job and a calendar of their own, and the question of who takes which appointment has to be settled somewhere every single week.

Seven physician visits a year is the floor, before the lab work and the physical therapy and the eye clinic. Spread across three siblings who each answer “maybe” to an invitation, that’s a lot of Tuesdays where nobody is sure.

In Marlow an unclaimed ride stays open and visible. As the day gets close and the ride still has no name on it, the circle is reminded, by the app rather than by whoever set the calendar up. If it’s still open, the organizer hears about it louder. Notifications are delivered by Apple, and Marlow’s own terms say plainly that nobody guarantees delivery, so the orange mark on the schedule is the thing to trust.

Months later, the activity feed says who claimed what and when, and search finds any appointment by driver. A calendar can tell you that cardiology happened on the 14th. Whether your sister drove or you did is whatever somebody remembered to put in the title.

Who wins? Marlow, on the commitment and on the record.

A read only calendar is still a calendar app built for a working adult

You can share the calendar with your parent view only, and that works. Google and Apple both offer it. What she gets is the same calendar app you use: a month grid, small type, a settings menu, notifications that all look alike, and your own meetings too if the wrong calendar gets shared. It’s a fine tool for her daughter. It’s the wrong tool for someone whose only job is to be ready at 9:00 and know who’s coming.

Marlow’s senior side is one screen. Today, in order, as a list rather than a grid. The next appointment sits at the top with the time to be ready and who’s coming, then later today, then tomorrow, then a line saying that’s everything. Text starts at 20px and follows the phone’s text size setting, and you can set it larger from your side. No account and no sign in; her phone is paired once with a code shown on yours. She can’t add, move or cancel anything, and that’s enforced at the database rather than by hiding buttons, so a wrong tap can’t change the schedule. If a ride isn’t claimed yet, her screen says it’s being arranged. Why the senior screen has no buttons goes into the reasoning.

The same information sits in a home screen widget and, while a ride is happening, on her lock screen. Her medicines and their reminder are on the same screen, and she can tap that she’s taken them. All of it in her language, whether or not it’s yours.

There’s one exception. If your parent manages her own appointments and wants to keep editing them, a calendar she can edit is the right tool. Marlow’s senior side is read only by design, and it has no button for her to reply with.

Who wins? Marlow. Her screen is what the senior side is for.

What each costs

Neither costs a family anything. Google Calendar is free, an Apple shared calendar is free, and Marlow’s everyday app is free, permanently, with no ads and no card; there’s no trial clock either. Plus is optional. The cost of trying Marlow is the setup and the double entry above, not money.

When the shared calendar is the better choice, and when Marlow is

If the person driving is nearly always the same person, there’s no coordination to do. The calendar’s reminders are all that’s needed, and Marlow would be a second app solving a problem you don’t have.

If a driver lives in a browser, or is on Android while the Android app is still in testing, the calendar is the tool that reaches them today. If the family’s whole week already lives in one calendar and nobody wants to type anything twice, that’s a real reason too. And if what you want is a wall calendar’s view of the year, a month grid with everything on it, a calendar app draws that and Marlow doesn’t.

Questions people ask

Does Marlow sync with Google Calendar?

One way. A ride you claim in Marlow is written into your own Google, Apple or Outlook calendar, with a warning if it clashes with something already there. Nothing is read back: appointments in your Google Calendar don't appear in Marlow. Two way sync is planned as part of the Plus tier and isn't built yet, and we'd rather you knew that before you moved anything.

Is an Apple or iCloud shared calendar any different from Google Calendar for this?

Not for the job in this post. Both share a calendar of events with named people, both offer a view only option, and neither has a state for a ride that still needs a driver. The practical differences are small: Apple's private sharing needs everyone to have an Apple Account using iCloud, and Google's sharing settings can only be changed from a computer.

Can't I just put “DRIVER?” in the event title and change it when someone agrees?

Plenty of families do, and it works until the person maintaining the convention is busy. The title is a note somebody has to edit by hand, the agreement usually arrives in a text message, and three months later nobody can say who drove how often. Marlow's difference is that the ride itself holds the state, the circle is nudged while it's open, and the activity feed keeps the record without anyone typing it.

Can my mother see her Marlow schedule on a shared calendar instead of the app?

No. Her Marlow screen is the app on her own iPhone, paired once with a code shown on yours, plus a widget and the lock screen while a ride is happening. Marlow doesn't publish her schedule to a calendar she could subscribe to. If she's comfortable with a calendar app and wants to edit her own appointments, a shared calendar is the better choice for her.

What about a driver on Android?

The Android app is built and in testing; Marlow is iPhone today. Until it ships, everyone who claims rides needs an iPhone with the app on it, and there's no web version. A shared calendar reaches an Android phone today, and we'd rather say that plainly than have you invite everyone and find out.

What does Marlow do with the appointment data that Google Calendar doesn't?

Less, in one sense. Marlow runs no analytics, no crash reporter and no trackers, shows no ads, does no location tracking, and sells nothing to anyone. Nothing is sent to a language model today, and if that ever changes it'll be announced before it ships. Google says Google Calendar doesn't use your content for advertising and doesn't sell your personal information, and Apple says it doesn't sell your personal data.

The rule is about the shape of the driving, not the features. If one person drives and everyone else just needs to know when, a shared calendar is the right amount of tool. If the driving is shared and the question of who keeps landing in a chat, the calendar has done its job and stopped, and Marlow picks up where it stops while writing each claimed ride back into it. How it works shows both halves in a few minutes.

Marlow is new, and iPhone today, with the Android app built and in testing. It isn’t a medical device or a safety system, it doesn’t vet, insure or background check drivers, and the everyday app is free, permanently, with no card.
