Span
Every measurement, right where you left it.
Coming Soon • iOS
Built for makers. No ads. No tracking.
It's on a Sticky Note Somewhere
The nook is 84 inches wide. You measured it. You wrote it down… somewhere. A sticky note, a text to yourself, the back of a receipt. Now you're standing in the store and the number is gone.
Span is a scratchpad for measurements. Type 25 3/4, 65.4 cm, or 30 x 40 and it just gets it — fractions, decimals, metric, imperial. Snap a photo so you know exactly which gap between which cabinets.
When it's time to build, the cut planner turns your measurements into a shopping list: how many boards to buy, which cuts come from each one, and what you'll have left over.
"Measure twice. Write it down once."

From Tape Measure to Cut List
Capture, organize, plan. Nothing you don't need.
Fast Capture
Open, type, done. Span parses fractions, decimals, ranges, metric and imperial — write measurements the way you'd say them out loud.
Dual Units
Every measurement displays in both systems automatically. 25 3/4 in and 65.4 cm, side by side. No mental math at the hardware store.
Photo References
Attach a photo to any measurement so you know exactly which window, wall, or gap it belongs to. Future you will be grateful.
Organized by Room
Group measurements by room with color-coded labels, then filter to just the kitchen when you're shopping for the kitchen. Pin the ones you reach for most.
Cut Plan Calculator
Pick your pieces, set your board size and saw kerf, and Span calculates the fewest boards to buy — with cut-by-cut instructions for each one.
Private by Design
Your measurements and photos stay on your device. No account, no cloud, no tracking. It's a notebook, not a service.

The Story Behind Span
I measured the same closet three times for one shelf project. Not because the closet changed; because I kept losing the number.
Span is the notebook I wanted in that moment. Type a measurement the way you'd say it, snap a photo, find it later in two taps. The cut planner came after I bought one board too many at the lumber yard. Again.
It's a simple app on purpose. Measurements in, plans out, nothing precious about it.
