Hemlog

The unit of record is one alteration, not one body

Most measuring apps keep a customer's body measurements. Hemlog keeps “this garment, this part, from this to that, done this way”. Customer → garment → alteration, so a second pair of trousers is its own record.

How the measurement was taken, kept with it

The same numbers do not always give the same look. Where you measured from, the heel height of the shoes they were wearing, standing or seated, and who measured — all four are kept alongside the measurement.

How much you could still let out

When someone asks whether it can go longer, the hem and seam allowance left is already in the record, so you can answer before you open the garment.

Measured, told, or worked out

A number you were given (“take up six centimetres”) is not the same as a number you measured. Every value carries which it was, and a record without enough measured values says plainly that it cannot be reproduced from what is there.

Washed before altering, or not

Shrinkage is the single biggest reason a garment finished to the same numbers looks different. Hemlog records the care label and whether the garment was washed first, and warns you when you duplicate an alteration that was made before washing.

Start from the last alteration

“Same length as last time” takes one tap. The part, technique, measurements, measuring conditions and machine settings carry over — and the numbers arrive as instructions, not as measurements, so you measure the new garment to confirm.

Centimetres or inches

Inches are entered and shown in eighths (31 3/8"). A value entered in centimetres is rounded to the nearest eighth when shown in inches, and Hemlog marks it with ≈ so you know. Switching units never changes what was saved.

Two levels of deletion

Removing a customer's contact details is separate from deleting everything. The first replaces the name with an anonymous ID and keeps the alterations, so your own record of the work survives.

Free and full access

Full access is available as a monthly or yearly auto-renewing subscription, or as a one-time purchase with no auto-renewal. If you cancel, you can still view, edit, delete and back up your records. What stops is exporting documents and combining search filters.

How your data is handled

Hemlog does not connect to the internet. There is no account, and nothing is sent to the developer.

If iCloud Backup is on for the device, Hemlog's data is included in Apple's backup, like any other app. That backup is handled by Apple, not by Hemlog.

No analytics or advertising SDK is included, so the developer has no way to see how you use the app.

What Hemlog does not do

• No automatic measuring from photos. Hemlog records what you did; it does not estimate.
• No tax calculation. What it prints is a receipt for an item taken in, and amounts are the sum of what you typed.
• No database of brands or model numbers. The brand field is free text.
• No sharing between shops or tailors.
• No support for kimono measurements (kujira-jaku).

Please note

This app is a tool for keeping your own records. It does not guarantee that a garment will come out the same, nor any legal effect. How a fabric shrinks or relaxes depends on the material and how it is handled. The final judgement is yours.
