About Relffits
Most food apps are built to keep you logging forever. Relffits is built so that one day you can stop. You log a meal by describing it in plain language. Before the AI answers, it asks you to guess the calories. Over time your guesses get closer, and that instinct is yours to keep, with or without the app. LOG IN SECONDS Describe a meal, snap a photo, scan a barcode, or say it out loud. Calories, protein, carbs, fat, and fiber in seconds. No database searching, no serving-size math. Meals you eat often resolve instantly from your own history, with no new analysis. GUESS BEFORE REVEAL Call the calories before the AI does. The reveal shows how close you were and tracks your accuracy over weeks. On a miss, open Where It Hid to see exactly which ingredients carried the calories you did not expect. THERE IS A FINISH LINE Relffits tracks five stages of calibration, from your first guesses to the point where you no longer need it. Every criterion is published up front and computed on your device from your own guesses, so the bar cannot move. When you get there, the app says so plainly and gets out of the way. FULLNESS FORECASTS Predict how long a meal will hold you, then tell Relffits what actually happened. Your prediction gets scored, and forecasts tune themselves to you, so you learn which foods genuinely hold you rather than guessing from a number. A COACH THAT LEARNS YOU Analyses can factor in a summary of how you actually eat: your usual meals, your typical portions, your guessing accuracy. Say "my usual yogurt bowl" and it resolves to yours, not a generic one. You can see everything it knows and switch it off anytime. FULL SCAN Photograph up to three angles of your plate, since a single photo hides depth and portions are the hardest thing to estimate. When something is still unclear, the app asks in everyday terms: about the size of your fist, or closer to two? EATING OUT Search a restaurant or photograph the menu, and see options ranked against the calories and macros you have left for the day. BARCODE SCANNER Scan packaged foods for label nutrition from a database of millions of products. Adjust servings and log with one tap. HISTORY AND PATTERNS Review any day, back-fill meals you missed, and see the weekly patterns worth repeating, including how your calorie accuracy is trending month over month. APPLE HEALTH Optionally read your weight from Health, and write the calories and weight you log back to it. NO STREAKS TO BREAK No shame for a missed day. Nothing here is designed to make leaving feel like a loss, because leaving is the point. PRIVACY FIRST Your health data is encrypted on your device with AES-256 before it ever reaches the cloud. We cannot read your logs. AI analysis is powered by Google Gemini. Meal descriptions, photos, and, when Personalized Coaching is on, a short summary of your eating patterns are processed by Google for nutritional analysis. AI features require opt-in consent and can be turned off at any time. Relffits provides general nutrition information for educational purposes only and is not medical advice. Nutrition figures are AI estimates rather than measurements, and are not a safety check for allergies.
What’s new
Version 3.2 · Updated October 15, 2026
The logging flow is rebuilt. Logging starts in a single bar now. Type it, say it, photograph it, or tap one of your usuals. No method to pick first, no database to search. Your guess got a real ruler. Drag it, or hold the plus and minus to move faster. The reveal is new too: your meal stacks up block by block, so you can see which ingredient was actually carrying the calories rather than just the final number. Every log now ends on a reward screen with your level and XP. Levels count logs, not accuracy. You go up for showing up, with a small bonus when a guess lands closer than your usual miss. Your level lives in Settings and follows you across devices. Logging is faster. Several seconds came out of the wait between pressing submit and seeing your food. You can cancel now. Log the wrong thing and Discard stops the analysis and hands your text back, so you can fix it instead of retyping it. A one time walkthrough explains the scoring the first time you open it. CHANGED: THE DAILY AI LIMIT IS NOW 10 A DAY, DOWN FROM 20 Relffits has no ads and no subscription, so I pay for the AI myself, and the price of the model goes up in January. Ten covers a normal day with room to spare. Past the cap, meals still log without the AI estimate, and it resets at midnight. If that turns out to be too tight in real use, email me at [email protected] and I will raise it. Plus bug fixes and a pass over the Privacy Policy and Terms to make sure every claim in them matches what the app actually does. Relffits is free, has no ads, and has no subscription. It is also how I am paying for chiropractic school. If it is useful to you, there is a coffee button in Settings. Nothing in the app is ever locked behind it.
