Dimemo vs Ruler ▸

Dimemo lets you write measured dimensions directly on a photo and keep them there. Jotting numbers alone in a notepad often leaves you wondering which measurement was which. Photos and numbers get separated — that’s the problem. Dimemo keeps both on one sheet from the start. ■ Snap, draw, and enter Photograph furniture, a window, or a wall on the spot (or pick from your library) and you’re in the annotation screen. Trace on the photo to draw a dimension line with arrows at both ends, then enter the value you actually measured and its unit. Choose from mm / cm / m / in / ft — your last-used unit is preselected. ■ Auto numbering keeps photo and list in sync Each dimension line gets a sequential number: ①, ②, …. Delete a line in the middle and numbers renumber automatically, so labels on the photo never drift from rows in the list. ■ Share photo + dimension list as one page Export the photo and the numbered dimension list as a single image or PDF. Send it to family, share it on site, or print it to take along — recipients can see which dimension is which without extra explanation. ■ Organize with folders Create folders such as “Moving,” “Kitchen DIY,” or “Site survey” to sort photos. Thumbnails show a badge with how many dimensions are on each shot, so the right one is easy to find. ■ Edit later Drag endpoints to fine-tune, move whole lines, edit values, delete, and undo. Pinch to zoom for fine detail. Besides dimensions, you can add text notes on the photo. ■ No automatic measuring Dimemo does not use AR auto-measure or scale conversion that infers other lengths from one dimension. Only values you actually measured with a tape (or similar) are recorded — so the source of every number stays clear. ■ Stays on your device Photos and dimensions are stored on-device and leave it only when you choose to export and share them.

Five measuring tools in one app. • Free — no subscription, no trial, no paywall • No ads and no account • Works offline, even in airplane mode • Nothing you measure ever leaves your phone ON-SCREEN RULER A real scale on your screen, in millimeters or in inches marked like a tape measure down to 1/32". Zero sits at the very edge of the glass, so you can butt the object straight against the phone. Drag the caliper and read the number on the line itself. Turn the phone sideways for the full length of the screen, and the numbers turn to stay readable. Full screen clears everything else away. CALIBRATION IN 30 SECONDS The ruler is accurate as it comes. If you want it exact, lay a bank card, a 1 or 2 euro coin, a US quarter, or anything else whose length you know on the glass and match the scale to it. It is an offer, never a wall in front of the app, and there is no limit on how far you can adjust it. PHOTO MEASURE Measure anything in a photograph. Put something of a known size beside it — an A4 or US Letter sheet, an access card, a business card, a coin, or your own length — draw the reference line along it, then draw the measured line across what you want to know. Both lines are there from the start and every end can be dragged at any time. A magnifier follows your finger above it, never under it, so a point lands where you meant it. Take a new photo or use one you already have. If the photo was taken from an angle, or the reference is far from the measurement, the app tells you instead of quietly handing you a wrong number. BUBBLE LEVEL A spirit level that is two instruments in one: a tube when you hold the phone against something upright, a round glass when you lay it flat, with the angle in degrees. Set any surface as zero and measure from it. The phone gives one short pulse the moment something is exactly level. Hold freezes the tool, and a reading can be held on screen behind a big button you can drag anywhere and make bigger with two fingers, for measuring where the screen cannot be seen. AR QUICK MEASURE Measure across a room with the camera. Aim the crosshair, press once, aim again: one distance, or a chain of them along a floor, a table or a wall, with the total as you go. It uses the depth sensor where your iPhone has one and detected surfaces where it does not, and when it is not sure of a point it says so instead of showing a number it does not believe. AR ROOM PLAN Walk the corners of a room and get its walls, its perimeter and its floor area. The plan draws itself in the corner of the screen as you walk, and it comes out as a real drawing with every wall measured, a scale bar and a north arrow. SAVED MEASUREMENTS AND PDF EXPORT Save anything you measure, name it, and keep it in folders. A ruler measurement opens back on the ruler, a photo measurement back on its photo, a room as its plan. Export through the normal share sheet as a clean A4 PDF: a table of names, measurements, tools and dates, photo measurements drawn on the photograph with each length beside its line, and a room drawn as a plan a builder can read. No watermark, and screenshots are never blocked. UNITS AND LANGUAGES Centimeters, fractional inches the way a tape is marked (3 3/8"), or decimal inches, climbing to meters or to feet and inches on their own. Units start from your region and are yours to change. 38 languages, right to left included, and a dark theme that follows your phone. PRIVATE BY DESIGN No account, no sign-up, no tracking, no network. The camera and the motion sensor are asked for only when you open the tool that needs them, and a refusal costs you that one tool, never the app. The camera measures and records nothing. WHY IT IS FREE Measuring apps turned into weekly subscriptions with ads over the ruler. This one is free, has no ads, and has nothing behind a paywall.
