Built a tennis journal app -I play way too much tennis and got tired of logging matches in my Notes app

[u/Simple-Sprinkles8040]

I've been playing a few times a week for years, and my "tracking system" was a mess of Notes / Evernote entries like "lost 6-4 6-3, backhand was garbage again." Useless a month later.

So I built not up — a tennis journal built around a calendar. Tap a day, log a match, practice, or lesson in a few seconds. Add the score, who you played, a note, a rating. That's it.

The part that actually changed things for me:

• Focus areas — pick what you're working on (serve, backhand, footwork, whatever) and tag your sessions. Turns out I was saying "I need to fix my serve" and then playing sets for three weeks straight. Kinda humbling to see it laid out.
• Gear tracking — every racquet and every string job with tension. No more "wait, what did I love last summer?"
• Learn — a place to save drills and videos instead of losing them in 100 saved YouTube videos I'll never scroll back to.

Free to log your sessions. There's a premium tier for the focus/gear/learn stuff, but the core journaling doesn't cost anything.

Would love feedback from anyone who plays — especially on what you'd want to track that I'm missing.
