Carbs Checker
Read full descriptionHide full description
Carbs Checker helps you estimate the carbohydrate content of a meal from a photo using AI. Instead of entering calories and nutrients in detail, Carbs Checker is designed for people who simply want to know, βAbout how many carbs are in this meal?β Take or choose a meal photo and AI will identify the meal and main ingredients, then show an estimated carbohydrate amount and breakdown. If the photo is difficult to interpret, you can add a short text explanation and run the analysis again. Your meals are added to todayβs log automatically, so you can quickly see your daily carbohydrate total. The default reference line is 300g, and you can change it anytime in Settings. The free version includes up to 3 AI analyses per day. Premium includes up to 20 AI analyses per day, 7-, 30-, 60-, and 90-day carbohydrate trends, weekly recaps, meal history, optional on-device meal photo storage, one-tap logging with βUsual Meals,β and an ad-free experience. Save meals you eat often as βUsual Meals,β and next time you can add them to todayβs log with one tapβwithout taking another photo or using another AI analysis. From checking a single meal to reviewing your daily and long-term carb trends, Carbs Checker keeps the focus on one thing: carbohydrates. β» Carbohydrate values shown in the app are AI-generated estimates and may differ from actual values depending on ingredients, serving size, seasonings, and preparation methods. β» Carbs Checker is not a medical device and should not be used for diagnosis, treatment, medication decisions, or other medical purposes. β» The reference line is a personal tracking value and is not a medical or nutritional recommendation.

Interval Timer

Whether you're settling in to focus or about to move, this is one interval timer for both. Switch between Focus mode and Workout mode with a single tap, and each one greets you with its own timing defaults, color, and wording. In Focus mode the work phase is called "Focus"; in Workout mode it's "Work." Breaks are called "Breathe" and "Long Break" β no mechanical countdown language, just a bit of warmth while you push through. β Who it's for - Anyone using the Pomodoro Technique to focus on study or work - Anyone timing HIIT or Tabata-style workouts - Anyone who needs phase changes to actually reach them while the phone is locked - Anyone tired of timer apps buried in ads β Free features - Pomodoro preset (25 min work / 5 min break, 15 min long break every 4 sets, 8 sets total) - HIIT preset (fully customizable duration and set count) - Custom work time, rest time, and set count - Start, Pause, Reset, Skip - Sound + haptic + notification on every phase change β arrives even when the screen is locked - Save 1 custom preset - Screen stays awake while the timer runs - Session summary screen after the final set - Available in Japanese, English, and Simplified Chinese β Pro features (one-time purchase, no subscription) - Unlimited custom presets - History & Stats (today / this week / all-time focus totals, a 7-day chart, and a session log) - Focus BGM (16 tracks to choose from, continuous play and volume control) - No ads - Restore Purchases supported Timing is calculated from elapsed seconds since start, not a countdown that decrements β so coming back from the background or a locked screen never leaves the display out of sync.
