🎾RacketLog – Remember Your Racket Tension

RacketLog is a dedicated racket tension management and match logging app for tennis and badminton enthusiasts.
With each match, string tension gradually decreases. However, it's difficult to determine by feel alone when and how much it has decreased, or when it's time to restring.
RacketLog helps you predict string tension trends and manage restringing timing with a simple post-match log.

🔧 App Key Features

✅1. Home Screen – View the current status of each racket at a glance

View your racket list and view current estimated tension, string condition, and expected re-string timing in a card format.

Visualize tension change graphs in sparkline format along with a list of recent match records.

Switch to another racket using the racket selection dropdown.

✅2. Add Records – Complete match records in seconds.

Easily enter match date, number of matches (sets), perceived tension (slider), string feel, etc.

Select string type (POLY / MULTI / HYBRID).

Add simple notes or equipment photos (optional).

Automatically estimates tension loss and updates racket condition upon saving.

✅3. Record Details – Analyze string condition after a match.

Analysis of racket tension on the day of the match (e.g., perceived 45 lbs → estimated actual 43 lbs).

Compare tension changes over the last 10 matches, showing increases and decreases compared to the average.
