Best Ketogenic Diet Apps of 2020

The ketogenic diet is simple in theory: keep carbs low, keep fat higher, and let your body do its “burning fat for fuel” thing. In practice? Keto is basically a daily game of “How many carbs are hiding in this innocent-looking food?” (Spoiler: the answer is always “more than you hoped.”)

That’s why 2020 was the year keto apps stopped being “nice-to-have” and became “please save me from accidentally eating a banana.” The best ketogenic diet apps of 2020 helped people track net carbs, dial in macros, plan meals, and stay consistentwithout turning every lunch into a math exam.

Below is a practical, in-depth guide to the top keto-friendly apps that stood out in 2020, what each one does best, and how to pick the right tool for your version of keto (lazy keto, strict keto, keto + fasting, keto + gym life, keto + “I meal prep once and then live off leftovers,” etc.).

What Makes a Keto App “Actually Good” (Not Just Pretty)

A keto app shouldn’t just count calories. Keto is more specific: carbs matter most, protein matters more than people think, and fat is the lever that makes the whole plan livable. Here’s what separates the great apps from the ones that make you rage-close your phone in the grocery aisle.

1) Net carb tracking (and the ability to switch views)

Many keto folks focus on net carbs (generally, total carbs minus fiber and certain sugar alcohols). A strong keto app makes net carbs easy to see, explains the math, and doesn’t bury the setting three menus deep.

2) A food database you can trust

The fastest way to sabotage keto is logging foods with incorrect nutrition info. Look for apps known for better data quality, verified entries, and flexible corrections when something looks off.

3) Fast logging: barcode scanner, restaurant items, saved meals

If logging feels like filing taxes, you won’t do it for long. The best apps make it easy with barcode scanning, searchable brands, restaurant menus, and “save this meal” shortcuts for repeat breakfasts (because yes, you are allowed to love eggs that much).

4) Macro targets you can customize

Some people do strict keto (very low carbs), others do moderate low-carb. Some lift heavy and need more protein. Your app should let you set carb, protein, and fat targets in a way that matches your goals and your lifestyle.

5) Planning features that prevent decision fatigue

Recipes, grocery lists, meal plans, and “what can I eat right now?” suggestions can be the difference between sticking with keto and eating a bowl of cereal while whispering, “It’s fine, I’ll start again tomorrow.”

6) The right level of “extra”

Some apps track fasting, sleep, mood, ketones, glucose, workouts, and water. That’s amazingunless you only wanted to track lunch and now your phone is asking about your emotional relationship with cauliflower rice.

The Best Ketogenic Diet Apps of 2020 (In-Depth Reviews)

1) Carb Manager (Keto Diet Tracker)

If keto had an “all-in-one Swiss Army knife” in 2020, it was Carb Manager. It’s designed specifically for low-carb and keto lifestyles, with net carb tracking front and center. People liked it because it wasn’t trying to be everything for everyone; it was trying to help you stay keto.

• Best for: Most keto beginners and intermediates who want an all-in-one tracker
• Standout strengths: Net carb focus, macro targets, barcode scanning, recipes, community features
• Watch-outs: Some advanced analytics and coaching features typically sit behind a premium tier

Real-world example: You scan a packaged snack, see net carbs immediately, and decide whether it’s a “keto yes” or a “keto… I’ll regret this” moment. Carb Manager shines when you’re busy and you want quick decisions without mental math.

2) Senza: Keto & Fasting

Senza gained fans in 2020 because it treated keto like a lifestyle system, not just a food diary. For many people, keto and intermittent fasting go togetherso an app that supports both (without duct tape and wishful thinking) is a big deal.

• Best for: Keto + intermittent fasting (or anyone who wants more lifestyle tracking)
• Standout strengths: Fasting windows, keto-friendly database, progress tracking beyond food
• Watch-outs: More features can mean more setup; keep it simple if you’re new

Real-world example: If you’re doing 16:8 fasting, Senza can help you log meals within your eating window and keep your daily carb total from creeping upward when hunger hits at 9:30 p.m.

3) Cronometer

Cronometer is the app you recommend to the person who asks, “But how many grams of magnesium did I eat today?” It’s known for more detailed nutrient tracking, and it’s a strong pick if you want accuracy and micronutrient visibilityboth of which can matter on keto (especially if you’re trying to avoid the dreaded “keto flu” slump).

• Best for: Data-driven users, people tracking micronutrients, and keto folks who want accuracy
• Standout strengths: Robust nutrient breakdown, flexible macro targets, net vs total carb options
• Watch-outs: The depth can feel intense if you only want basic logging

Real-world example: You’re feeling low-energy and realize your sodium/potassium intake has been off all week. Cronometer helps you spot patterns that basic calorie apps miss.

4) MyFitnessPal

MyFitnessPal wasn’t built exclusively for ketobut in 2020, it remained one of the most popular trackers because of its huge food database and easy logging. If you’re the kind of person who wants one app for general nutrition plus the ability to run a keto macro setup, it’s a practical choice.

• Best for: People who want a general-purpose tracker that can support keto macros
• Standout strengths: Large database, flexible logging, ecosystem integrations
• Watch-outs: Keto-specific features (like net carb emphasis) may take more manual setup

Real-world example: You eat at chain restaurants a lot. The database helps you log quicklythen you manually watch carbs to stay keto-friendly.

5) KetoDiet App

KetoDiet App is a strong pick if your biggest keto challenge is not knowing what to cook. In 2020, a lot of people didn’t quit keto because they “failed”they quit because they got bored. Recipe-focused apps solve the boredom problem.

• Best for: Home cooks, meal preppers, and anyone who wants recipe inspiration that fits low-carb goals
• Standout strengths: Low-carb recipe library, planning support, keto-friendly cooking guidance
• Watch-outs: If you rarely cook, the recipe strengths may be overkill

Real-world example: You plan three dinners for the week, build a shopping list, and stop “panic-ordering” meals that accidentally come with a side of hidden sugar.

6) Total Keto Diet

Total Keto Diet leans into the “make keto easier” angle with recipes, tracking, and planning tools. In 2020, this style of app worked well for people who wanted structureespecially those who didn’t want to build meals from scratch every day.

• Best for: Beginners who want recipes + tracking + planning in one place
• Standout strengths: Keto recipes, meal planning, grocery/shopping list style support
• Watch-outs: Meal plan features often vary by subscription level

Real-world example: You pick a keto recipe, add ingredients to a list, and shop with fewer impulse buys because the app already told you what you need for the week.

7) Keto.app

Keto.app is built around a clear keto premise: track foods, track macros, and keep net carbs visible. The experience is straightforward, and the app is especially handy if you like building custom meals and want an app that “speaks keto” by default.

• Best for: People who want simple keto tracking with net carbs front and center
• Standout strengths: Net carb focus, barcode scanning, custom foods/meals
• Watch-outs: Recipe and coaching ecosystems may be smaller than all-in-one giants

Real-world example: You make a “go-to” salad bowl, save it, and log it in two taps for the next month. That’s keto consistency without decision fatigue.

8) Stupid Simple Keto

Sometimes the best keto app is the one that doesn’t make you feel like you’re enrolling in a graduate program. Stupid Simple Keto became popular because it aimed for easy, visual tracking. If you love minimalism and hate scrolling through endless menus, this one deserves a look.

• Best for: “I just want to track carbs and move on” users
• Standout strengths: Simplicity, quick logging, visual approach
• Watch-outs: Less depth than power-user apps (which may be a feature, not a bug)

Real-world example: You’re in a drive-thru line, you want a fast decision, and you don’t want to manually build a recipe for “burger, no bun.” Quick logging keeps you honest without stealing your afternoon.

9) My Macros+ (Macro Tracker)

My Macros+ is macro-first, which makes it a strong option for athletes or structured eaters who live and die by targets. Keto users who train regularly often want macro control rather than a purely recipe-driven app. In 2020, this kind of tool was especially helpful for people balancing keto with performance goals.

• Best for: Lifters, runners, and macro-focused users running keto-style targets
• Standout strengths: Barcode scanning, flexible meal structure, macro goal control
• Watch-outs: Not “keto-specific” in the way Carb Manager or Senza areso you’ll set your keto targets

Real-world example: You can keep carbs low while still hitting protein targets for strength trainingwithout guessing whether you’re under-eating.

10) Lifesum (Keto-Friendly Plans)

Lifesum is more of a broad nutrition platform, but it offers keto-oriented tools and plans that can support low-carb tracking. In 2020, it appealed to people who wanted structure, coaching vibes, and a lifestyle app that didn’t feel overly clinical.

• Best for: People who want guided plans and a modern “nutrition coach” feel
• Standout strengths: Plan-based approach, flexible tracking methods, lifestyle support
• Watch-outs: Keto specificity depends on plan level and settings

Real-world example: You prefer a guided plan and “what’s next” prompts rather than building everything manually. Lifesum can act like rails on a pathhelpful when motivation is low.

How to Choose the Right Keto App (Without Downloading 12 Apps and Crying)

Step 1: Decide your keto style

• Strict keto: prioritize net carbs + accuracy (Cronometer, Carb Manager)
• Lazy keto: prioritize fast logging + simplicity (Carb Manager, Stupid Simple Keto)
• Keto + fasting: prioritize fasting tools (Senza, Carb Manager with fasting features)
• Keto + performance: prioritize macro control (My Macros+, Cronometer)
• Keto + cooking: prioritize recipes & planning (KetoDiet App, Total Keto Diet)

Step 2: Make sure it matches your “friction tolerance”

If you love data, go deeper. If you hate data, go simpler. The best app is the one you’ll use on a random Wednesday when you’re hungry, busy, and tempted by a free office donut.

Step 3: Test one normal day

Log one typical day of eating. If the app feels annoying on Day 1, it will feel unbearable by Day 14. Keto success is about consistency, and consistency is about reducing friction.

Pro Tips: Get More Results from Your Keto App in 2020-Style Real Life

• Save your repeat meals. If you eat the same breakfast often, turn it into a saved meal. The less you type, the longer you’ll stick with tracking.
• Watch “keto-ish” packaged foods. Always check net carbs and serving sizes. Some products are basically “keto” the way a kiddie pool is “the ocean.”
• Don’t panic over one off-plan meal. Use your app to learn, not to self-punish. One meal is a data point, not a personality test.
• Track electrolytes if you feel off. Many keto discomforts come from hydration and electrolyte balance, not “keto failing.”
• Use trends, not daily perfection. Weekly patterns matter more than one weird day when your carbs jump because you discovered onions exist.

Real-World Experiences (500+ Words): What Using Keto Apps in 2020 Actually Felt Like

Let’s talk about the part no one puts in the app store screenshots: using a keto app is less like “effortless wellness” and more like having a tiny, honest friend in your pocket who quietly says, “Are you sure about that?”

In 2020, a lot of people started keto with big motivation and a grocery cart full of optimismalmond flour, cauliflower rice, and enough eggs to start a small chicken-themed economy. The first week with a keto app often felt empowering: you log meals, you see net carbs stay under target, and you get that satisfying little sense that you’ve cracked the code. The app becomes a scoreboard, and you’re winning.

Then real life shows up. You’re invited to a birthday dinner. The menu doesn’t list nutrition facts. Someone suggests sharing fries “just a little.” And suddenly the keto app isn’t a scoreboardit’s a flashlight. You realize your usual “harmless” sauces are sugar delivery systems. You discover that “keto snack” can still be a carb bomb if you eat three servings while watching TV. You learn that the biggest value of an app isn’t guilt; it’s clarity.

Many users found that the first major breakthrough came from building repeatable routines. The moment you save a standard breakfastsay, eggs, avocado, and coffeelogging stops feeling like a chore. You tap once, and you’re done. Apps like Carb Manager and Keto.app made this “repeat meal” workflow feel natural, and that’s huge because keto isn’t hard on your best dayit’s hard on your busiest day.

Another common experience: the “net carb education era.” In 2020, plenty of people entered keto thinking carbs were just bread and pasta. Then the app taught them about fiber, sugar alcohols, portion sizes, and how quickly carbs stack up from “healthy” foods. Users often described this as a shift from guessing to managing. Instead of asking, “Can I eat this?” they started asking, “How does this fit my day?” That one mindset change is where apps quietly earn their keep.

For keto + fasting folks, the experience often became about structure. People used fasting windows to reduce snacking and simplify decisions. An app like Senza helped users treat fasting like a plan rather than a willpower contest. When the evening cravings hit, it wasn’t just “don’t eat”it was “your window starts tomorrow at X,” which turned chaos into a schedule.

The most consistent users often reported a surprisingly emotional win: less food anxiety. When you can check net carbs quickly, you stop spiraling into “I blew it” thoughts. You adjust. You learn. You keep going. Keto apps didn’t make keto effortless in 2020but they made it less confusing, more trackable, and far easier to restart after a messy day. And honestly, that’s the real superpower.

Final Thoughts

The best ketogenic diet apps of 2020 weren’t just about trackingthey were about removing guesswork. If you want an all-in-one keto platform, start with Carb Manager. If fasting is part of your routine, Senza is a natural fit. If accuracy and deeper nutrition data matter, Cronometer is hard to beat. If you need help cooking and planning meals, KetoDiet App and Total Keto Diet can keep keto from getting boring.
