CalTopo for Android

The level of detail combined with customizable overlays and the ability to be used off-line is superb.

Lots of functionality though often provided through non-standard if not obscure UI functions. Hard to operate in direct sunlight (which is mainly an Android problem though the developer can help by providing contrast filters) as well as in the dark (too much light, no red filter). By far biggest issue is that the app gets so slow after a day’s worth of work with multiple tracked teams that it can not be used any longer. Why not provide a filter that allows me to see just the teams I was on? Instead everything is always on making the UI cluttered and unbearably slow. I wonder if developer actually uses it themselves on SAR missions?

I have no interest in sharing my account login across services. SSO is a huge security and identity risk that only benefits the issuers so they can track you and lock you into their services. I'd be happy to use this app and service if it had it's own login option.

Useful but buggy. Last week the latest released version bricked my Android 13 (yes it has the latest iOS version) and forced a manual reset at phone during a pretty inopportune time. Love the web app. But the iOS app could use some more testing.

This is a great app but would be a lot more usable if able to use Google Watch to navigate to points!
