The design sits right before the needle runs.
You create a project and upload the design. Your customer opens a link on their phone and sees the tattoo on their arm, no app and no account.

From stencil to link
-
Upload the design
A photo of the stencil or the file from Procreate. Envis cuts out the paper white, you enter the width in centimetres, the height follows from the design.
-
Link and QR come with the project
Every project gets a 16-character link and a QR code. The customer scans it at the counter or gets the link on WhatsApp. You can set an expiry and revoke it any time.
-
The customer sees it on their own arm
Camera on, arm in frame. The design sits on the skin, follows the movement, and can be moved, turned and scaled with two fingers.
-
Snapshots and replies come back to the studio
Every snapshot from the phone lands in the project, along with the placement the customer chose. A tap on "bigger" or a line like "closer to the wrist" arrives as a message while you are still at the counter.
What the customer gets
A link that opens in the phone's browser, with your studio's name and the design in its current version. When you upload a new version, the image on the open phone changes in the same second, without anyone reloading the page.
Two fingers move and turn it, a double tap brings back your suggestion. The size on the arm is an estimate from the pose, the centimetres are yours to set. The camera stream stays on the device. Only the snapshot the customer sends goes to you.
Every version stays
The customer wants the rose smaller and the vine further in. You upload v2 and note what changed. Both of you see the same row, and v1 stays visible in case the first one wins after all.

Who this is for
For studios where placement gets decided at the appointment and the stencil is applied twice. Envis saves the second application. The stencil itself and your own judgement stay where they are.
The camera recognises forearm, upper arm, shin, thigh, hand, shoulder, chest and neck. Fingers, the back seen from behind and anything under clothing are hard for it. In bad light, or when the arm leaves the frame, the page says so.
Free during the beta
Envis is free during the beta, with up to 50 active projects per studio, and when pricing arrives you hear about it four weeks ahead by mail.
Questions that come up at the counter
Does the customer need an app?
A browser is enough: Safari from iOS 16.4 or Chrome on Android. Inside the Instagram or WhatsApp browser the page gets no camera. It then asks to open the link in Safari or Chrome.
How accurate is the size on the arm?
The page estimates the length of the forearm from the pose. That varies by ten to fifteen percent. Your centimetre figure is the truth, the camera shows proportion and position.
Where are the images stored?
Designs and snapshots are stored with Cloudflare in the Western Europe region and are reachable only through a signed link with an expiry. The camera stream never leaves the phone.
Can I take a link back?
Any time. The link stops the second you tap revoke, including on a phone that has the page open right then. Archiving a project does the same. You can also give links an expiry.
Can my artist get in too?
During the beta one studio belongs to one email address. Invitations for more artists are the next step and arrive before pricing does.
What about iPhone?
Works in Safari from iOS 16.4. Tracking needs a device from around 2019 onwards, older ones get a choppy preview. The page checks before loading and says so when it is not enough.
