A minimalist and bold logo for a tennis scoring app, cleverly incorporating a stylized tennis ball made of geometric shapes, blending vibrant yellow and green colors reminiscent of tennis courts. Intersect the tennis ball icon with a sleek pencil or pen shape, symbolizing the app's scoring and note-taking capabilities. Subtly integrate numerical digits or tally marks within the design to represent the core function of score tracking. The overall composition should be simple yet eye-catching, with a perfect balance of minimalism and conveying the app's purpose through iconic elements like the tennis ball, pencil, and scoring motifs. Possible name: 'TennisScore Pro' or other concise suggestions.
