Walk the boundary
Stand on each corner stone and tap. The phone holds still for about 10 seconds, averages its GPS readings and drops the jumps. The screen stays on, and every corner is saved as you go. For a curved bund, trace it as you walk.
Polam Kolathaluపొలం కొలతలు
Measure your land in acres and cents, guntas, gajam and ankanam.
Walk the boundary with your phone, type the side lengths from your tape or deed, or draw the plot on the map. Polam writes every side’s length on the sketch and tells you honestly how sure the answer is.
Land area
1 acre 14.86 cents
± 9.5 cents, normal for phone GPS at about ±3 m
In Telangana: 1 acre 5.9 guntas. As house plots: 5,559 gajam.
Yellow ring = how far the GPS reading can be wrong (±1.4 m), drawn to scale
Every side’s length is written along its edge. The corner stones are lettered A, B, C, D: the same letters the app uses when you type sides.
In short
- Free. You never have to pay for measuring, saving or backup
- No login and no account
- Your plots stay on your phone. Back up to a file any time
- Telugu first, in 11 languages
- One small ad, only under the result
Three ways to measure
Pick the one that fits where you are. Each one ends in the same answer: a sketch with every side labelled, and the area in your units.
Type the side lengths
Enter 3 to 6 sides in feet, metres, yards or links (with the chain named). Add one diagonal and the shape is fixed. Add the other one and Polam checks that the plot closes.
Draw it on the map
Tap the corners on the satellite picture, from anywhere. Find the village by name, or paste coordinates or a Google Maps link. The pictures can be old, and the app says so.
Your units, the way your records say them
Andhra Pradesh records use acres and cents. Telangana uses acres and guntas. House plots are sold in gajam, and in the Nellore and Tirupati belts in ankanam. Polam shows every one of them, never a bare “1.29”.
- Acre ఎకరం
- 100 cents = 40 guntas = 4,840 gajam = 43,560 sq ft
- 1 cent సెంటు
- 48.4 gajam = 435.6 sq ft
- Gunta గుంట
- 121 gajam = 1,089 sq ft
- Gajam గజం
- 1 square yard = 9 sq ft
- Ankanam అంకణం
- 72 sq ft in most places, 36 sq ft in some. You choose, and the answer changes on screen. Polam never guesses.
A house site, typed from the tape
Sides 40 ft and 30 ft, diagonal A–C 50 ft
- Gajam (square yards)133.33
- Land area1,200 sq ft
- Ankanam of 72 sq ft16 ankanam 48 sq ft
- Ankanam of 36 sq ft33 ankanam 12 sq ft
- Cents2.75
For a plot smaller than 20 cents in size, the app shows gajam first.
An honest ± on every GPS answer
A phone’s GPS position is off by a few metres. Other apps hide that and give one confident number. Polam works out how much those metres can move your area, and draws it as a yellow ring, to scale.
The same phone accuracy (about ±3 m) gives the same ring around both plots. On the smaller plot, the ring is a bigger part of the area.
Tape entries use no GPS, so they get a sharp line and no ring.
Four side lengths alone are not enough
Four sides can make many shapes, so Polam gives a range and asks for one diagonal. One app showed 4,240 sq ft for sides of 20 · 33.25 · 20 · 27.25 ft. The most those four sides can hold is about 598 sq ft.
A plot report you can hand over
Save any plot as an image or a PDF: the sketch with every side and lettered corner, the area in every unit, the ± band, how it was measured, the date, and the survey number if you add one. Share it on WhatsApp or any app you choose.
The report can include your plot’s corner coordinates. It leaves your phone only when you share it.
Your land plots
Your plots stay on your phone. Every corner is saved as you walk, so nothing is lost if the phone rings. Save a backup file whenever you like, and the app shows the date of your last backup.
