This questions comes up every time. I copied the answer i gave the last time at

Yes, this comes up most of the time when I post about it. Which is totally understandable since looking at it from the outside, they do the same in the sense of being an alternative to Google Timeline.

I have a vision where Reitti should be heading and this is not the timeline part. It will always be there to look at it, see your movement patterns, your visits and so on. Also the live view part, where you can share your location with others, with other users, instances or via magic link is one essential part which will always be there. Lot of users connect via this to their friends and families which is awesome when Reitti can help with this.

But, the Geo location is only the underlying data we need to create something which helps me (and maybe you) in remembering things. I “suffer” from Aphantasia and I struggle to get to my memories without any external trigger and that is the reason I created Reitti. To have a thing, i can occasionally look at, bring in pictures and emotions back into my knowledge. Where memories is the first step towards that goal.

So, for me this is the main difference between these two. But do not take my words for granted, test them out and take the one you like more. Since I started Reitti 6 months ago (actually a little bit longer) I did not follow on other projects that much and maybe they all converge to the same conclusion.

I am a little bit hesitant in adding a comparison in the Readme since I do not want to compare Reitti with other solutions. What I want more than a comparison is to make the idea behind Reitti clearer so anyone can build its own opinion which one is better suited.

I hope I got my point of view transported. English is not my main language and I did not bothered to let some LLM look over it.

If something needs more explanation, feel free to ask me anything.
