...What really frustrates me about Caltopo (and this, coming from an early adopter and a pro subscriber since it became a thing), is that they stopped licensing their data to other companies, in order to strengthen their competitive position and get people using their own app. That's certainly their prerogative, but I think it was poorly timed. Caltopo's app is still pretty terrible (re-loads every time you navigate away from the foreground, sucks battery like crazy, handles large data sets very poorly). Gaia and BCN were filling a gap that Caltopo had left, and Caltopo removed that option without actually improving their app enough to make it a satisfactory replacement. So we get a whole bunch of companies jockeying for position, and the end result is that you and me get hosed.
Late jumping into this thread but thank
@Wanderlust073 for the bump on it today. By the way, I have played around with FatMap a bit in the past and it was a bit buggy, clunky and laggy when I tried it out a while back. Perhaps it is better now.
Now back to
@LarryBoy. You've got me really curious about your experiences and the way you've been using CalTopo on your phone because I'm quite different with my opinions about it and feel very grateful for it now. So now I have to ask, how are you using it that makes it suck battery on you? Do you use tracking with it? Do you use it on an iPhone? I've had a very different experience with their more recent updates and I've been using their mobile app since the first beta version became available and so I can say it has come a long way since and I like where they've been taking it. It's far better than it used to be with how I use it now. I currently have a Samsung S10 as my phone and will agree that it is a battery drain when tracking at medium and high levels. I only recently began trying out tracking with it. I did a couple days on a recent trip at "medium" level and that's been the only time I've notice a big battery drain with the app. I went from about 70% battery to 30% battery across 14 miles and about 8 hours with my normal use of the camera app and so forth. That's a lot more than I'm used to when not tracking while keeping my phone in Airplane mode as I typically do in the backcountry. I switched it down to the "Low" level to try that out and battery life improved dramatically. I also found that the resulting track in low mode was still quite accurate. I then used it that way on my last trip and it was still quite accurate until the next day, where the canyon got much more narrow and that resulted in a track with a lot of crazy bounce to it. I think that's pretty typical for most GPS devices though. Again, battery life was hardly worse for the wear using that low mode.
Now, I haven't been one to track much in the past and don't know how often I'll keep doing it, because I've always been one to design and mark up my route with CalTopo's feature rich website first and then sync it to my phone with the mobile app and just use the active GPS location mode on my downloaded map to keep track of my location in realtime and keep myself on course. In the past I'd exported to PDF for use with Avenza Maps app, and then moved on to exporting to GPX for a while and used with Gaia like so many others have and still do, but with the developmental progress that has been made to CalTopo's new app, I've not found myself missing any other app. I did use BCN a bit a long time ago, but at the time, found it to be not very intuitive at all before I moved on with the others I just mentioned. Perhaps it got a lot better itself as well after I left it. For what it's worth, I do like to keep in mind that Gaia and many of these other navigational apps have been around a lot longer and have had more time and more resources dedicated to them for development early on and have the advantage of being more mature now, but since CalTopo has now been growing and expanding a bit and receiving more of an investment in funding and personnel, it's clear their app and web interface is becoming more and more polished, in my opinion. For example, the web interface just got a makeover in recent weeks and now has a number of keyboard shortcuts that can be used for basic mapping and marking functions. It's taken me a bit to get used to the new locations of some of the items, like where to click to access your save maps and other data, but all in all, I do think it's getting a lot better, and a lot nicer as time goes by.
You also said it always loads from scratch anytime you transition another app into the foreground? I've not experienced that. I bounce back and forth between my phone's camera and CalTopo apps numerous times throughout the day when on trail. Switching back and forth between the two via "recent apps" or "open apps" shortcut is almost always seamless, fast, and responsive with virtually no lag time or re-loading for me between either app.
Now, I don't think I can speak to the large data sets issue you also mentioned. Perhaps that may be because I may not qualify as a power user with it. I mainly use to to make sure I'm on the right route I laid out before hand, help me get back on course if I go astray a bit, and measure out different distances and check elevation. The only thing I find it lacking in now from what other apps seem to have, is that when you do enable tracking, it only offers up a running duration while the track is in progress. There's no pacing info, it does not seem to maintain the duration after you stop the track, and does not auto-pause when you stop for a break like others.
I'd say one of the biggest things I really enjoy about it over others is how it maintains all the little different icons you can use with waypoints marked out in the web interface. I like being able to use different icon sets to distinguish campsites or places to look for potential campsites from strategic water sources, from places to look for rock art, ruins, etc, to big view points and so forth. I also really like all the different layers and even outside map sheets and shared sheets you can add, save, download, and/or sync to and from your account and over to the app.
Anyhow, I guess what I'm really interested in now is what exactly have I been missing out on (aside from the tracking data mentioned) by leaving Gaia and BCN or any other behind by going full on with CalTopo for the time being?
