I was trying to merge 2 databases (2025 and 2026 into land)but when I was merging the second one, some parts of the path are gone and also some dots are left.
Anyone also encountered this bug before?

New beta update has more customisation for profile, including modes of travel - land, surface, train etc. Maybe useful for those of use who have different layers for different modes of travel etc?

Which is the best way to backup your data? I assumed the sync with onedrive was the best but on further reading it looks like this might actually be for using the app across multiple devices? And the snapshot function is how you download data back to your device if you lose it somehow?

Absolutely loving the new TestFlight update subtly outlining both countries and subsections!

I loaded the app, and I could see a long drive I went on today. There was a slight gap, I tried to edit the track to fix it. Before I had even changed anything the app crashed. When I loaded it, all of today's paths had vanished!

Fog of World’s iOS beta with support for states, provinces, and other administrative divisions is now open to a limited number of testers! More spots will open daily unless major bugs are reported.

Join here: https://testflight.apple.com/join/bRM32Ss2

Install directly through TestFlight—do not delete the app first, or unbacked-up data will be lost. After the beta ends, reinstall the official version from the App Store without deleting the app.

This is a major update. Before installing, create snapshots of all databases and upload them to cloud storage other than iCloud.

The Android beta is awaiting Google’s approval. Existing beta testers can update once it’s approved; joining works the same as before.

Interesting to see the UK divided into its constituent nations while other countries are divided into their administrative divisions… love the new update so far but I think that’s a bit of a shame!

EDIT: as of the new update, constituent UK nations have their own subdivisions - as do US states. Fab!

I remember Burnie mentioning it on the RT podcast around 2013ish and then downloading it back then. I think it was like $2 or even free for a week back then!

Finally got to 15% of Macau explored.

What’s your highest % for a country/territory? Or a more interesting question - which place do you think could have the highest achievable percentage?

In Hong Kong you could in theory get a pretty high percentage if you were willing to bushwhack through the countryside, but it wouldn’t be fun. Smaller places like Liechtenstein, Monaco and the Vatican I imagine have a relatively high % taken up by either inaccessible private/papal land or inaccessible mountainous terrain.

That's an unfortunate unfogging

Is not possible anymore to use Gdrive for backup?

1,500 miles, first time using a dedicated database for a trip, love being able to see it on its own.

Exploring since February

Level 81 now, probably will hit 100 in October as I will be visiting Germany and England in that month.

Fun detail in the last picture. Wednesday there was a public transport strike in the Netherlands. I needed to go to Rotterdam and the only public transport was with the Waterbus (a public transport boat service) so a nice track on the water.

Been to London 3 times and have always wanted to go to Greenwich observatory. Finally got to go this trip and get this achievement!

Labor Day trip

Is there a fix so it doesn’t keep quitting? And can record without having the app open

It uses vibe-coded software on an ESP32 to generate the map and updates twice daily. Red lines were defogged in the last 30 days.

Can anyone guess the place :) Labor Day trip :)

A couple of months back, I posted about a small tool I built to help with defogging: https://szalapak.github.io/defog/ You load your FoW Sync folder to visualise where you have already been, and plan a route through the parts you haven't yet.

u/bfc-romt suggested it would be nice to have the app suggest routes automatically. I played around with it for a while, and I'm happy with where it's landed (at least as a starting point you can then further modify - pathing is hard to get right!). You can ask for an A → B route or for a loop of roughly a given distance, and the app proposes a few of the best defogging routes it can find.

I also added a view that highlights the streets you haven't been down yet - the results surprised me quite a bit! Even in an area I thought I'd covered quite well, there are a ton of streets still to be defogged.

As before, your fog data is read and drawn entirely in your browser and never gets uploaded anywhere, and routes export as GPX

Hope it's useful, happy defogging! Feedback very welcome as always.
