There is no shortage of diet and nutrition apps on the app store — apps designed for specific and rigorous dieting systems, services that harvest all of your dietary data to sell to third parties, and calorie-counting cudgels that all too often brow-beat their users over the smallest deviations from Ideal Intake™. Moderation — developed by Dominic Williams — is a food diary app that removes all of the least-pleasant aspects of diet tracking apps and focuses in on one simple question: Was your meal healthy or not?

Logging meals is as easy as tapping “Healthy” or “Unhealthy” — whatever that means for your goals.

Removing the Friction from Meal Tracking

Moderation's best feature is its simplicity — no need to scan barcodes or record calorie counts after every meal; all you do is click "Healthy" or "Unhealthy" in four daily categories (Breakfast, Lunch, Dinner, and Snacks). What you consider to be a "Healthy" meal vs an "Unhealthy" meal is completely up to you and your diet tracking goals. For example, I have been trying to reduce the amount of sugar I add to my coffee every morning, so lately I have been rating my Breakfasts as "Healthy" or "Unhealthy" based on that metric. Folks who are trying intermittent fasting might rate a meal as "Healthy" if they ate nothing, and folks trying a plant-based diet might rate a meal as "Unhealthy" if they sneak in a little bacon. That's the beauty of Moderation: you can self-evaluate your daily meals based on what changes you are trying to make in your eating habits, or what dietary system you are trying to follow. This relieves much of the pressure that other diet and nutrition apps put on their users to meet a certain target, or stack up against some arbitrary standard — the same pressure and sense of judgement that so often causes people to give up on making healthier diet choices.

Useful features like rich notifications and Siri Shortcuts support make logging your meals as low-effort as possible.

Moderation also makes it easy to log your meals with custom-set reminders, rich notifications to quickly record a meal, and Siri Shortcuts support that allows you to integrate meal tracking into any of your custom Shortcuts routines. I often find myself struggling to consistently use habit-tracking apps because, well, I don't get into the habit of tracking my habits. Moderation's built-in reminder system has made it easy for me to quickly log a meal right from the notification, and Siri Shortcuts support has helped me make sure I log my healthy (or unhealthy) eating habits every day.

Design Aligned with Purpose

Moderation's simple and straightfoward premise is packaged with an appealing, elegant design as well as intuitive, clear feedback mechanisms. Each day in a month-view calendar is given a gradient from green to red based on what proportion of that day's meals were rated as "Healthy" or "Unhealthy". Streaks of all-healthy days are celebrated in the month-view, and used as a goal to beat in the "Keep Motivated" section (notably, "Unhealthy" streaks are not as prominently displayed, in keeping with the apps positive and encouraging style). Even the button design for each meal reaffirms the relaxed nature of Moderation, with clever use of Emoji to visually represent both "Healthy" (🥑,🥗,🍲,🍏) and "Unhealthy" (🙈,🍕,🍔,🍩) meals.

My worst eating day tends to be Friday, because Friday night is D&D night — AKA fast food and candy night!

Basic metrics are maintained on-device to give you insight on what days of the week you often struggle to eat healthy, and which meals usually trip you up on any given day. A running percentage of healthy meals provides a quick glimpse of your eating habits over the last seven days and the current month. Importantly, Moderation has a user-first privacy stance; all of the data you log in Moderation is kept on-device, and there are no ads or other data-harvesting components in the app — making it a great choice for the privacy-conscious.

"Moderation in All Things"

I've been using Moderation for about a month to track my own diet, and I've never had more success with habit tracking in any other app. However, there are some features (some apparently on the horizon) that I wish Moderation would add to really flesh out the experience. Repeating reminders (like those offered by Due) would make it even harder to forget to log a meal. Additional data visualization options, custom goal setting, and the ability to export your data would all be welcome additions to an already excellent app.

There are many good diet tracking apps out there — Moderation is a great diet tracking app because of the uniquely positive, balanced, and affirming way in which it is designed. Scanning food barcodes is laborious, counting calories often brings feelings of shame and failure, and strict definitions of "Healthy" and "Unhealthy" often don't fit with a person's unique goals. Moderation avoids all these pitfalls while still delivering useful metrics for self-evaluation and motivational encouragement to continue improving your diet. Tracking your eating habits has never been so easy, or more importantly: so painless. Moderation is available for free on the app store.
