FWIW, the site at: https://maps.openrouteservice.org/reach also fails to compute accurately from my location for an hour, but does work accurately for 50 minutes or less. If nothing else, maybe I'm a good test case?
Sharing only so the developer has another test case :)
The three points on the right are only reachable by ferry, so add approximately 1.5 hrs to the travel time. Plus the one at the bottom right would require the driver to pass through the downtown core of the city of Vancouver; even without the ferry time, it wouldn't be possible to do that in under 1 hour from the origin.
Edit: but it did work if I lowered the time. Interesting work though.
There's a similar blob going from Seattle to Preston, which appears to contain some impossible routes where you would get off I-90 and then circle around via highway.
As long as you stay out of the mountains and don't cross any water it seems pretty accurate as a first approximation.
If it helps, the 3 points going east are probably due to 2 canyons that do go east of town, one of which splits into 2 roads after a mile or so. And many of the others are similar in that, yes, there is a road that would extend your reach in those directions... but not quite where the map is drawing it. There are two areas that are complete anomalies: the path going NE through Springville and the one going SSW towards Levan have zero correlation with any reasonable roads - those both are flying straight over mountain ranges.
In 8h you can get to Salamanca(East of Barcelona) according to Google Maps, so like half of Spain should be marked.
It's also interesting that according to this, you can get to Monaco(6h 34m on Gmaps) , but no to Marseille (4h 54m on GMaps).
4 hours by car from San Francisco. It says you can't reach South Lake Tahoe, but Google Maps (and my experience) show that it's usually about 3 1/2 hours.
Probably don't use your home address.
Unless you can connect it to an identity, and have a particular reason to target that identity, it's not much of a reveal.
Or even under HN traffic, if someone mentions to have used it, you now have a few hundred or maybe thousand potential locations for a username instead of the entire western world (and even that is an assumption that could be wrong). If you're serious about this, and if the username seriously tries to stay anonymous (as a bunch of people here do), this does have an impact.
Why not? Addresses are public information anyway.
The key to winning in the property space is definitely non-obvious, but I love to see innovative search tools popping up from time to time. Long may it continue!
The most basic usage is missing!
But whis works: https://maps.openrouteservice.org/reach
I used this Python code  to figure out where to live that had a reasonable commute.
However, these do not account for traffic conditions. The paid Google Maps API provides that information however and it is easily incorporated into the code.

Nice idea though.
1. There seems to be a problem with water https://imgur.com/a/TjyeKmV
No ferries or bridges in the south
2. And there seems to be a problem with sharing (Chrome on Mac)
3. Tried to change the option to bike - and it got be redirected to Cleveland
I put in my work address and a time of one hour. It shows two of my previous home address as being over an hour away. It takes me about 40 - 50 minutes to get to work now from my current address. It took my about an hour from the other address.
Also, there needs to be a way to clear the map. Right now, I'm just overlaying times. I don't know if I'm just missing it on the UI but there needs to be a way to distinguish between adding more areas and replacing an area.
Seems like a UI bug, those things disappear when the browser window gets to be a certain height.
Also, I checked the reverse on one of the directions. So from A to B and B to A. One way shows that it is possible to do in an hour, while the reverse shows that it can't be done. While I understand that road conditions may be different in each direction in general, in this specific case, I know the conditions are the same.
There's also some weird artifacts, like parts of roads skipped. Places designated as "an hour away" that are only reachable by first driving through areas designated as unreachable in an hour.
It seems to have issues with paths into or crossing the alps.
And apparently, I can't get to Evanston, IL. Ferris Bueller would be disappointed.
I did a similar thing and built isochronic maps while at a start-up for business intelligence back in 2014. I'm curious how you got the going, data processing and all.
When I'd done it I set up all roads and continents in OSM but it took quite a bit of work to do so. I'd used Osmium to import everything into postgres and set it up to using pgrouting. It took quite a bit of work but with a lot of query mangling it had a lot of traversal cost variates (street type, population, daytime pop) it had pretty good approximations of Google!
The most awful part was trying to set up the data to be usable, quick, and deal with large queries (set it up for a maximum 150km without issue), but it was a great challenge!
Unfortunately, to do this, I just had to keep entering new searches with incrementally new times. Anyways, just a feature idea. Nice work.
Interesting concept though!
This might help the OP (also other readers and for reference)
It might be competing with the OPs app, but Here.com has a solution for this in one of their developer APIs(https://developer.here.com/documentation/routing/topics/requ...), it returns an isoline(contour) based on multiple options(max distance, max time or max fuel consumption) similar to the OPs solution
I would happily pay $10 or more for an accurate customized commute map. The rational value is likely way higher for families looking for an area to buy in which good commute times for all.
Idea for another project: (I tried it too but gave up quickly) Since now my friends are all over the US and the world, we argue about the best city to meet at. It would be awesome if there is a website that takes your and your friend’s budget, current city, and visa requirements and figure out the best place to fly to for everyone.
Of course, this will be easy to monetize if you can get referral commission from airlines and hotels.
When I look at where I live and set 45mins, what I get is not fully covered by what I get for 50 mins. But if a place is within my 45min car ride, I would expect that place to be included to the 50min car ride zone. Am I missing something?

When I looked in my area, it looked semi-accuraete, but far from reliable when I compared to google maps: https://s22.postimg.cc/lxfvu3ag1/How_far_can_I_go_-_Oalley_f...
^ It shows that about the furthest I can go in 2 hours (east) is Tanner, WA, while in reality I can go about twice that distance and do frequently, nearly all the way to Ellensberg. The north/south part looks correct.
We're turning on a free user account for people to try out:
It was a side project for us that we thought was cool enough to be a standalone product.
IsochrOnes. Catchment areas are something different.
deployed 2 days ago by the api.data.amsterdam.nl team.
Sort of a "heatmap" of distance.
That way you could discover the most "well-connected" locations within a city, and even potentially use that data for urban planning.
specifically the upper peninsula. it looks like it doesn't have enough data as you go towards the rural north, which doesn't shock me at all, and extrapolates from that.
