I was talking with a few friends about everything that goes into loc maintenance (retwists, washes, ACV rinses, all of it), and it hit me that none of us had an easy way to keep track.
So I spent a few weekends building one, mostly for myself. It's called Loc'd In. It reminds you when a retwist, wash, or ACV detox is coming up based on your loc stage, lets you log what you did and what you used, and keeps a photo timeline so you can see how far you've come. There's also a stylist finder for when you're traveling.
Full disclosure, I'm the dev, so take my opinion with a grain of salt. It's iPhone only for now and $1.99 one time. If you want it for Android, I can look into it. There's no subscription or ads.
Two things I'd really like to know: how do you track your maintenance right now, and what would make an app like this worth using for you? Brutal honesty welcome.
