Collect colours out of the real world

Point the camera at anything and capture its exact colour into your collection. Rare shades are rare because of where they are — a particular sky, a particular shopfront — so filling the wheel means going outside and looking properly at things you walk past.…

Tell creators which brand deal is a scam before they reply

Fake sponsorship emails are now the standard way to phish creators: a plausible brand, a contract PDF, a link that takes the channel. Forward it here, get a verdict, and every report makes the next creator's verdict better. Who it is for: anyone with an…

Answer the application questions in your own words, faster

Paste the job description, and it drafts the long-form answers using what you have already written about yourself — your history, your phrasing, your actual projects — rather than the beige paragraph a generic model produces. Who it is for: anyone doing…

A daily planner built for a brain that will not do lists

Standard to-do apps assume you will open them, read a list, and feel motivated. For a lot of people that is exactly the thing that does not happen. This one starts the day for you: one task at a time, timers that assume you will lose the thread, and no…

A budget that only has to survive one trip

Not lifetime personal finance. One holiday, one wedding, one conference: set the number, log what you spend, see how much of it is left before you buy the next round. When the trip is over the budget is over. Who it is for: people who will never adopt a full…

Tell me whether the plane wifi is worth paying for

You are at 30,000 feet, the wifi has stopped, and you cannot tell whether the connection is dead, the session expired, or the captive portal wants you to log in again. This checks all three and tells you which, in one tap. Who it is for: anyone who works on…

Solve a murder through the victim's phone

You are handed a phone — messages, photos, deleted drafts, a maps history — and the case is in there. No puzzle screens, no inventory, just the interface you already know how to use, which is what makes it unsettling. Tie one chapter to a real cafe where a…

A selfie, and you in another century

Take one photo and get yourself rendered into a different era or setting, convincingly enough to want it printed. Then sell the print, the mug, the case — the image is the hook, the object is the margin. Who it is for: the enormous casual audience that pays…

See the clothes on you before you buy them

One photo of you, any product page, and you see the garment on your own body at your own proportions instead of on a model who shares none of them. The point is cutting the returns you were always going to make. Who it is for: online shoppers, and eventually…

Swipe until you and a friend agree on something to watch

Two phones, one QR scan to pair, then you both swipe through films and shows until something gets a yes from both of you. It stops the forty minutes of scrolling that usually ends with nothing being watched. Who it is for: couples and flatmates, and anyone…

Somewhere to put every restaurant you save off social and never visit

You save the reel, you forget the reel. This catches shared places from the videos you send each other, pins them to a map, and surfaces them when you are nearby and hungry — with the group you saved them with, since it is never a solo list. Who it is for:…

A map of where free community meals are being served today

Community kitchens, mosque and church distributions, charity kitchens, funeral meals, food banks with an hour left on the tray. Volunteers post what is being served and where, the map shows what is still going, and people who need it can just walk there. Who…

Show two people every time they nearly met

Both of you opt in, both of you hand over your location history, and the app finds the overlaps: the same concert in 2019, the same terminal on the same afternoon, the cafe you both sat in a week apart. It turns a coincidence into something you can look at.…

Burn a memory and watch it go

Upload the photo, the screenshot of the conversation, whatever it is. It curls, chars and goes up while sad music plays and the phone crackles under your thumb. You get a video of it burning, which is the part people will actually post. Who it is for: anyone…

A map-first social app for the things that only happen in person

Not a feed with a map bolted on, a map that is the whole interface. Who is running this evening, which sauna has people in it, who is around and actually up for meeting. Zenly proved people want this and then got shut down, leaving the space empty. Who it is…

Exit interviews, published

The real reason people leave a job gets said in the pub, never in the exit interview, and never on a jobs profile where the whole industry can see it. An app for posting why you actually walked out, so the next person reads it before they sign. Who it is…

A mail app where the calendar sits in the same bottom bar

Half of email is scheduling, and the current answer is two apps and a lot of switching. Put mail and calendar behind one bottom bar: read the message, see the day it is asking about, block the slot, reply, done, without ever leaving. Who it is for: anyone…

Short videos that quietly turn into a story about you

A feed that watches what you linger on and weaves those interests into an ongoing audiovisual novel in real time, so the story bends toward whatever you keep watching. The original pitch added a wagering layer on top to sharpen the pull. Who it is for: the…

Pharmacy stock finder that tells you which one actually has it

You get handed a prescription and then start the ring-round: four pharmacies, three of them out of stock, one that thinks it might have it tomorrow. The app shows which nearby pharmacies actually hold what you were prescribed, lets you reserve it, and orders…

Second-hand furniture marketplace with the van included

The reason people give away a good sofa instead of selling it is that moving it is the hard part. Bundle a two-person pickup slot into the listing price and the whole category becomes liquid.
