Don't hand over a gift. Make them win it.

A question only that person can answer. A code made out of your date. A place they have to reach. You put it together in ten minutes, send them a link, and they open it on their phone with nothing to install.

Where did we first meet?

Here it's just any old question. In your adventure it'll be something only the two of you know.

The problem

You agonise over the gift. It's open in ten seconds.

  1. 01

    What sticks isn't the object.

    It's the hour before it. The blank face, the clue that took a while, the moment it finally clicks. The gift is still there at the end — it just stops being the only thing that happened.

  2. 02

    Doing it by hand takes weeks.

    Envelopes, handwritten clues, things hidden around the house. It works once, and it cannot be repeated or shared.

  3. 03

    What already exists feels like a toy.

    Loud colours, mascots and confetti. And there is usually something to install or an account to create before you can start.


Envilo doesn't replace your gift. It builds the road up to it.

In motion

This is what it looks like when it reaches them.

Nothing to install, no account to create. They open the link on their phone and from there the afternoon is theirs.

How it's done

Three steps and it's done

  1. You write the challenges

    A question only that person can answer, a code made out of your date, a place they have to reach. You type them the way you'd type a message.

  2. You send the link

    By WhatsApp, tucked inside a card, printed as a QR. They open it on their phone with nothing to download and no account to create.

  3. Then you sit back and watch

    They work through it, get stuck, get there. At the end is whatever you left waiting: a letter, a photo, a place, a gift.

On the ground

The adventure can also go out into the street.

You mark points on the map and the step will not open until they actually get there. Their phone guides them with a radar: warmer or colder, never the direction.

  • A treasure hunt around your town

    The bench you used to sit on, the square from the first photo, the doorway. Five places that mean something only to you, and a prize at the end of the trail.

  • A tour with no guide and no leaflet

    Build your city's route and sell it or give it away. Whoever receives it walks it at their own pace, on the day they choose, discovering each stop instead of following an umbrella.

  • How it works

    You pick the point on the map and how close they must get, from a few metres to a city block. The phone compares its position with yours and only opens the step on arrival. Nothing to install.

The index

13 instruments at your disposal

Every challenge is a different apparatus: questions, codes, places, photos, the phone's own sensors. You combine them in any order, with no limit on steps, and each one takes a minute to fill in.

Questions


  • Riddle

    Write a question with an open answer. You can optionally attach an image as a visual clue.

  • Numeric code

    Enter a key number: a special date, a year, a PIN… The recipient must guess it.

  • Trivia / Multiple choice

    Create a question with several options. Only one is correct. Great for fun facts or shared memories.

Interactive


  • Image puzzle

    Turns a photo into a sliding plate, from 3×3 up to 6×6. Higher levels add a move limit, a timer, and a reference image that runs out.

  • Switch panel

    A breaker panel. Each throw moves several contacts at once, so the sequence has to be worked out rather than guessed. At high levels the margin of moves is exact.

  • Sequence pattern Phone

    A connection panel lights up a trace and it has to be repeated with a finger. Higher levels grow the grid, speed up the playback and can ask for it in reverse.

  • Photo timeline

    Upload up to 8 photos and set their chronological order. The player sees them shuffled and must drag them from oldest to newest.

Multimedia


  • Custom video

    Upload a video with a message, a clue or a memory. The recipient watches it before answering.

  • Secret radio

    The player sweeps a radio dial through the static until they find the station where your message comes through clearly. Higher levels add decoy stations and require holding the tuning.

Physical


  • Geolocation (GPS) Phone

    A radar guides them to exact coordinates. It requires staying inside the radius, not just passing by, and checks how accurate the signal is.

  • Shake the phone Phone

    A seismograph measures the phone's real acceleration. Half-hearted shaking will not do: it takes genuine force, and the energy drains if the player stops.

Timing


  • Unlock date

    The step stays locked until an exact date and time you choose. The recipient sees a countdown — or it opens immediately if the date has passed.

  • Timed pause

    The step locks for a duration you set (seconds, minutes or hours) from the moment the recipient reaches it. They see a real-time countdown.

The right resistance

Make it cost something. But make it open.

Every challenge has five levels, and a level isn't a label: it changes the tries, the wait after a miss, whether a clock is running and whether the on-screen aids show. Your eight-year-old nephew and your brother, who thinks he's very clever, don't need the same thing.

The workshop

Building a challenge is writing one sentence.

Pick the type, write what they'll read, tick the right answer. That's one step. Repeat it as often as you like, drag to change the order, and publish: the link and the QR come out ready.

The ending

All of this leads somewhere. You decide where.

When they beat the last challenge, whatever you left waiting opens up. It isn't a congratulations screen: it's what you put there, and it can be any of these five things.

  • A letter

    Formatted however you like and as long as you need. It opens full screen, right after the last lock.

  • A voucher for…

    A weekend, a dinner, a trip. The card that says what you've given them; from there it's between the two of you.

  • A video

    One you filmed yourself or one that means something. From YouTube or Vimeo, and only whoever reaches the end gets to see it.

  • Tickets

    A PDF they download: concert tickets, a booking, the boarding passes. Whatever they need on their phone as they walk out of the door.

  • A link

    A button that goes wherever you say: a playlist, a photo album, a page you built for the occasion.

You pick it at the end, in the adventure's settings, and you can change it any time before it's published.


What you design is only read by whoever lives it.

A link says nothing on its own. Whoever opens it supplies the meaning.


The timeline

Your photos, in the order you lived them.

Upload up to eight memories and set their order. The player receives them shuffled and has to rebuild the story by dragging. Try it with these three.

Drag them from oldest to most recent.

    Timeline
    The faces

    At the end of all this someone is opening something.

    The instruments, the rounds and the stopwatch are the means. This is the reason.

    • A family laughing together outdoors

      An afternoon at home

      Six challenges spread across the house and the garden. The last one opens the envelope with the tickets.

    • A student walking in a gown on graduation day

      A graduation

      The trail ends in the first-year lecture hall. The letter nobody expected is waiting there.

    • Two people walking through a city's old quarter

      A weekend away

      No guide and no leaflet. A city explains itself once you have to look for it.

    The cost

    Public or private. That is the whole decision.

    The mechanism is identical in both: the same challenges, the same steps, the same ending. The only thing that changes is who can reach your adventure.

    The questions

    Frequently asked questions


    Ten minutes for a short one, four or five challenges. If you start digging out photos and writing the letter for the ending, an afternoon. The tool isn't the slow part.


    No. They open the link or scan the QR and play from their phone's browser. No downloads, no account, no email.


    13: questions, codes, trivia, GPS, video, audio, puzzles, shaking the phone, sequences, switches, photo order, date unlock and pauses. You get all of them, free ones included.


    A public one is free and goes up on Explore, so anyone can play it. A private one ($9.99, one-time payment) only exists for whoever has your link, and you can add a password and an opening time.

    I set it up for my boyfriend's birthday with 8 steps through the places where we've shared memories. It took me an afternoon, and he still talks about it. The GPS step that took him to the restaurant of our first date was the perfect ending.

    I created a route around Valencia for my friends who were visiting. I published it in Explore and it turns out more than 200 people have already played it. Didn't expect that at all. It's amazing to see so many people enjoying your work.
    Cristina V., ValenciaTourism
    I'm not great with technology but my daughter helped me set it up to surprise my wife on our 25th anniversary. Easier than I thought. She was very moved. I don't usually write reviews but this deserves it.

    You know how it works. Now build yours.

    You'll have the first one done in ten minutes. And whoever receives it installs nothing: they open a link and they're already inside.
