Track anything by text message. No app, no login.
Think of it as a notebook that lives in your text messages — every text is saved with the date and time, so you build a history you can look back on. (Summaries and trends are on the way.)
+1 (206) 350-3997Invitation only — you need a join code from someone who already uses it.
Text a measure and a value — your weight, blood pressure, steps, sleep, mood, whatever you're keeping an eye on. It's logged with a timestamp: one line, whenever you want.
weight 178 bp 120 80 steps 8500 mood pretty good
The measure is the first word; whatever comes after it is saved exactly as you typed it — a number, several numbers, or plain words. Nothing to set up.
Text /recent weight — or any measure — and VitalSigns texts your latest entries
back, newest first:
weight (last 3): 178 — Jul 16 08:12 179 — Jul 14 07:55 180 — Jul 10 08:03
It's all there in your texts — nothing to open, nothing to log into.
bp 120 80.bp 120, 80.steps 10,000 — but you never have to; steps 10000 is exactly the
same.mood cloudy, a little off.The measure is only a word, so VitalSigns can track anything you'd jot down over time — not just vitals:
hours 6.5 rainfall 0.4 coffee 3 fillup 11,234 10 54.99
Hours worked, the day's rainfall, cups of coffee, a gas-station fill-up — the same one-line habit, whatever you're tracking.
Everything above works with no setup. If you'd like, you can tell VitalSigns what information belongs in a particular kind of entry — so it can check each one and keep the parts straight. Sign in at vital-signs.billbak.tech and open Measures.
Each part is called a field, and you give it a name, a kind of value, and an optional unit:
| Type | Accepts |
|---|---|
number | Any number, e.g. 98.6 |
whole number | Counts with no decimals, e.g. 12000 |
text | Words, kept as written |
For example, define fillup with three number fields — mileage, gallons, cost —
then text:
fillup 11,234 10 54.99
…and it's checked and stored as those three parts.
If an entry doesn't match, nothing is lost. VitalSigns replies with what it
expected and doesn't save — just send it again. For the three-part fillup above,
texting fillup 10 54.99 (only two values) gets:
"fillup needs 3 values: mileage, gallons, cost. Not saved."
You can also mark a measure as one that adds up over time (like steps or miles) — that's what will drive running totals and averages in reports later.
A measure you haven't defined — or one defined as a single text field — simply keeps whatever you text, exactly as written.

iPhone or Android? Either one. If it can send a text, it works.
