NFC tags
Stick a tag on gear or a jar. One tap with your iPhone opens SeshTime.
A SeshTime tag is a small NFC sticker you put on a piece of gear or a jar. Write it once from the app. After that, a tap with your iPhone starts a session.

Compatible tags are NTAG213, NTAG215, and NTAG216. Use a blank tag you can write yourself.
Open tag setup in SeshTime and hold your iPhone near the sticker until it confirms.
Prefer your own flow? Tags work with a Shortcuts automation too.
Tags use SeshTag, seshtag/1.0, so the format is documented rather than locked away.
The details
Everything here stays on your devices and in your own iCloud. There is no SeshTime account and no tracking.
A tag carries a seshtime.io link. Your entries stay in the app. This website keeps no database of tags.
If SeshTime is not installed, the link opens a short page on this site that does not print the tag’s identifier.
Tags written before the move to seshtime.io keep the old address until you rewrite them.
SeshTime is coming to iPhone, iPad, and Apple Watch. No account to create, nothing to track, and your journal stays in your iCloud.
