Compare watermelons in one photo before choosing at the grocery store or market. Watermelon Checker uses visible patterns, color and surface features to help you compare their appearance. It does not measure sweetness or taste. TAKE A PHOTO. COMPARE YOUR OPTIONS. - Use your camera or choose a photo from your gallery. - Analyze up to 16 detected candidates and see up to 2 recommendations that meet the app's appearance criteria. - Find recommended fruit using numbered markers on the photo. - View appearance scores and the reasons for the top recommendation. - Photo analysis runs on your device. IMPROVEMENTS IN THIS VERSION Refined fruit boundaries, visible field-spot measurements and stripe analysis help handle stickers, glare and nearby watermelons. A field spot is the area where a watermelon rested on the ground; it is assessed only when visible. A hidden spot is not treated as proof that no spot exists. Rewarded-video loading, manual retry and reward-expiration handling have also been improved. These updates do not change the scoring formula or guarantee identical rankings across different photos. ADS AND OPTIONAL AD REMOVAL Complete a rewarded video to receive six hours of unlimited analysis without further video ads. Banner ads may still appear in Settings. An optional one-time in-app purchase removes ads, and purchase restoration is available. Ads, consent updates and purchases require an internet connection even though photo analysis is performed on your device. PHOTO TIPS For comparison, photograph two or more watermelons in good light and keep each fruit clearly visible. Small, blurry or heavily obscured fruit may be excluded. Depending on the photo, the app may return one recommendation or no measurable candidates; it does not detect every watermelon. UNDERSTANDING THE RESULTS Scores are visual reference points for entertainment and comparison, not measurements of Brix, taste or freshness. Lighting, angle, reflections and the visible area can change the score and ranking of the same fruit. Use the results as one reference when choosing a watermelon, not a guarantee of quality. Available in English, Korean, Japanese, Simplified Chinese, Traditional Chinese, French and Spanish. Made with LOVE in Canada.
