"I don't want to lose all my data" is one of the most common reasons golfers stick with an app they've outgrown. It's a reasonable worry, switching costs are real, but it's worth separating what you'd actually lose from what just feels like you would.

1Your old data isn't deleted, it just stays put

What actually happens

Switching apps doesn't erase anything in your old one. Your round history stays exactly where it is; you simply stop adding to it and start logging new rounds somewhere else. Most golf apps don't offer a direct import from competitors, so in practice your history ends up living in two places rather than one.

Why this matters: "losing" your data and "leaving it behind in an app you're not opening anymore" are very different things, even though they feel similar in the moment.

2You don't need 20 rounds to get a real handicap again

Faster than you'd think

The World Handicap System only requires 3 scores to establish an initial Handicap Index. A new app starting your count at zero doesn't mean weeks of playing with no number; a handful of rounds gets you a usable index again quickly.

Why this matters: the "starting over" feeling is mostly psychological. The actual technical requirement is a lot smaller than it seems.

3Backfill your recent rounds manually if you want a head start

Optional, takes a few minutes

If you remember your last handful of scores, courses, and dates, entering them manually in a new app gets your handicap established faster than waiting to log new rounds one at a time. It's a small bit of data entry that pays off immediately.

Why this matters: you don't have to choose between switching apps and having an accurate number right away.

If the thing actually holding you back from switching is uncertainty about what you'd be giving up, the honest answer is: less than it feels like. Your history stays where it is, your new handicap catches up fast, and you can always keep both apps open for a while if that makes the transition easier.
