Comments For This Page

I used this all the time to figure out acreage for leasing land or fertilizing. Now I can't. This was my favorite tool because of the ease. I guess I'll have to look elsewhere
On 18th March 2024
what r yall on abt this site is really useful (to me). the least yall could do is say why.

On 17th March 2024
Is this a joke? What have you done with the previous program? This is complete garbage.
On 17th March 2024
You can't do anything now. Bring back previous version!
On 17th March 2024
Please bring back the old version.
On 17th March 2024
Ditto on all of the comments, going to have to go back an do it on paper which will work way better than what this is.

By Alan on 16th March 2024
New version does nothing .. no polygon drawn
.. no area etc. When are you going yo fix this issue
By Naeem on 16th March 2024
Been using this for 10 years or more, very sad to see you guys ruin it.

New version is horrible.
On 16th March 2024
Please go back to the prior version. This version is unusable for me.
On 15th March 2024
Doesn't work for area:(
On 12th March 2024
The updated version is really disappointing. Please go back to your previous version or at least reinstate the same features. What have you done!!

On 11th March 2024
Unbelievable! It doesn't even work anymore.
On 11th March 2024
Not gonna lie, the update really screwed everything. The map is crap so impossible to select anything accurately and no idea how to actually have an area reading at all.
No idea why every company that has a good product suddenly decide to screw up their product. Why try to fix something that was not broken? Just absurd and non-sensical.
On 11th March 2024
horribleeee!!!incredible what they are had done with a past nice tool%ud83d%ude31%ud83d%ude2d
By JA on 10th March 2024
You people are insane you took a wonderful program and screwed it all up. I am looking for a program quite similar to the old program, because I won't be using this anymore.
Can't you just leave this alone.

On 8th March 2024
Like others have said, the changes made have made this program unusable.
On 8th March 2024
I work for a national lawn care company. When I started six years ago, I tried about ten different measuring tools until I settled on the best, this one. I liked the ability to toggle markers (on to move them, off to clean up the image for presentation to customers), the interaction with google maps was adequate, and the ability to measure different areas on a property with the sum total was what really set this platform apart.

Whatever you did on the most recent update is garbage and the platform is no longer usable.
On 8th March 2024
We are a Lawncare company and we measure up the lawn sizes for new enquiries using daft Logic, and have done this for many years, where we can measure different areas (i.e. front and rear lawns) separately at an individual property.

Any clues how this can be done??

A quick fix will be most appreciated!

By Nick Thomas on 8th March 2024
Has this been deprecated? If so, I am disappointed it is gone but still thankful for the use of the tool for several years.
On 7th March 2024
No point in using this tool anymore. As with most everything these days the dilution and erosion of quality/ functionality is typical.
On 7th March 2024
Street names are not showing up on satellite images.
By Daniel Kintz on 7th March 2024
Guys, this new version is hideous. Map is tiny, full screen version doesn%u2019t show the actual calculation for the area you%u2019ve created, trying to pinch zoom (iPad) usually adds an unwanted node%u2026 it%u2019s just horrible. I honestly don%u2019t know what benefits you were aiming for but I genuinely can%u2019t see a single improvement. Oh%u2026 being able to drag your created area outline is great, everything else is considerably worse. PLEASE revert back to the previous version.
By Mike on 6th March 2024
The new version looks nice, but all the good features are gone.
even the "delete last point"
On 6th March 2024
The new leaflet map format has taken away any useful functionality that Daft Logic had for measuring exterior areas. We use it for measuring buildings and cannot see buildings in 3D so cannot measure height and surface area of walls. Is there another website or app (paid or free) that offers functionality like Daft Logic had before update this week?

Daft Please change it back. The tool is now unusable.
By Ian Murray on 6th March 2024
horrible
On 6th March 2024
This new platform is terrible!!
On 6th March 2024
This new version is absolutely useless for my job of measuring lawn and hard surface areas. Need the old version back online as a matter of urgency!!!

On 6th March 2024
The old version was the best of the best and the new one is unusable,
On 6th March 2024
Please move back to Google Maps.
On 5th March 2024
This is pretty complicated to measure buildings and property if we can't load the site as per previous version, almost makes it worthless.
