Love may be unavailable from two until four

One of the larger dating apps would begin taking profiles offline for scheduled maintenance next year, under a scheme that treats a person's romantic presentation as a system in need of patching. For two hours a night, users could not be seen, liked or messaged while the app's assistant rebuilds them. A changelog would follow in the morning.

Dating apps have steadily added automated tools that write or edit biographies, select photographs, suggest opening lines and coach users through conversations. Profiles are increasingly shaped by engagement data, with apps running continuous experiments on wording and presentation to improve match rates. Visibility on the major platforms is tied to paid tiers and ranking systems, so who is shown, and when, is already a product decision rather than a personal one. At the same time, consumer software has normalised scheduled downtime, versioned releases and changelogs, and that vocabulary is spreading into how people describe themselves. Surveys consistently report fatigue with app-based dating and a drift back towards in-person events.

Deborah Finch, 41, a payroll administrator, would be sitting on the edge of her bath at 01:52 on a Tuesday, typing a message to a man named Colin about his allotment. She would have a second sentence planned, about her own tomatoes, when a banner appears at the top of the screen. Her profile is due to enter scheduled maintenance in eight minutes, it would say, and unsent messages may not be preserved. She would send the first sentence on its own. It reads, in full, “Sounds lovely.” Colin would not hear about the tomatoes for eleven days.

The scheme, which the app would call Profile Health, follows from a change most users have already accepted. Profiles on the larger apps are now largely assembled by an assistant, which drafts the biography, picks the photographs and tunes the tone to whatever has performed. A profile built that way is not a description but a running service, and running services drift. “A profile that is never maintained stops resembling the person,” a spokesperson for the app would say. “We would rather take it offline for two hours than let it represent someone who no longer exists.” Unplanned downtime, in this framing, is a person in a bad mood.

During the window, a profile would be neither visible nor searchable. Conversations already under way would display a grey notice reading “This person is currently undergoing maintenance”, with an estimated time of return, which the app would describe as more honest than the existing “active 2h ago”. Likes received during the window would be held in a queue and released at the end in the order they arrived, which the company would describe as fair. Matches formed in the final minute before a window would be flagged as provisional. Nothing said during maintenance could be held against anyone, because nothing could be said.

Windows would be assigned rather than chosen. Free accounts would receive a slot by rota, and because the app must keep enough profiles online to sustain the evening peak, a portion of them would fall between seven and nine. Subscribers could select their own window, with the small print noting that two users whose windows never overlap cannot match, a condition the app would report as “scheduling incompatibility” next to the scores for humour and ambition. Marcus Doyle, 29, a warehouse supervisor, would choose three until five. “I put it in my bio,” he would say. “Not available three till five. It's the most honest thing on there.”

Each window would end with a changelog. Users would wake to a short list of what had been done to them overnight: a hobby deprecated after fourteen months without a supporting photograph, a height rounded to the nearer whole number, an adjective retired for underperformance. Hannah Reeve, 36, a dental receptionist, would find that “enjoys quiet evenings” had become “open to quiet evenings”. “I didn't ask for that,” she would say. “But I also didn't disagree.” If a rebuilt profile performed worse than its predecessor over forty-eight hours, it would be rolled back automatically. The people who liked the newer version would not be told.

The scheme would produce its own social life. A support forum would fill with people whose windows coincide, comparing changelogs while they wait to exist again, and at least one couple would report meeting there, in the two hours a night during which neither of them could be matched with anyone. Employers would be asked, informally, whether a profile's window could be moved to accommodate shift work. A small number of users would begin describing themselves, in conversation and then in person, as available between certain hours. The app would count this as engagement.

Deborah Finch's profile would return at 04:00 with three changes. “No drama” removed, after analysis suggested the phrase performs poorly with men who own allotments. “Values reliability” added. The age of her dog corrected from four to five, which was true, and which she had forgotten. Colin's window would run from four until six. By the time his profile came back, hers would be twelve minutes into the morning rota, moved forward to relieve the evening peak. They would not have been online at the same time since the tomatoes. The app would list them as 91 per cent compatible, and remind her, daily, that Colin is undergoing maintenance.
