Why I Switched from Simple (Fasting App) to Nutrola

Simple had a great fasting timer, but when I tried to seriously track my nutrition, it fell short. Here is my experience switching to Nutrola after 40 days.

Simple is one of the best fasting timer apps I have ever used. I want to start with that because this is not a takedown piece. Simple's fasting interface is beautiful, the educational content about intermittent fasting is well-written, and the overall design of the app is polished. If all you need is a fasting timer with some nice features around it, Simple genuinely delivers.

But I did not just need a fasting timer. I needed to track what I eat during my eating windows with real accuracy and real nutrient depth. And that is where Simple and I parted ways.

This is my story of switching to Nutrola for nutrition tracking, what the first 40 days looked like, and why the combination of a simple phone alarm for fasting plus a dedicated nutrition app turned out to be far better than one app trying to do both.

How I Ended Up on Simple

A colleague recommended Simple when I mentioned I was interested in intermittent fasting. She had been using it for months and loved the fasting tracker, the water intake reminders, and the educational articles about different fasting protocols.

I downloaded it, took the onboarding quiz, and was immediately impressed. The app was visually appealing, the fasting timer was intuitive, and the content about 16:8, 18:6, and other fasting schedules was genuinely helpful for a beginner. I learned a lot from Simple's educational material during my first few weeks.

The subscription cost was around eight to twelve dollars per month depending on the plan duration. Not cheap, but I figured the combination of fasting tracking and food logging in one app justified it.

Where Simple's Nutrition Tracking Fell Short

After about a month of using Simple primarily as a fasting app, I started trying to use it seriously for food logging. I had weight loss goals that required more than just fasting — I needed to understand my caloric intake, my macro ratios, and ideally my micronutrient status.

The Food Logging Was Too Basic

Simple's food logging feature felt like it was added to complement the fasting timer, not to stand on its own. The search function worked for common foods but struggled with anything specific. Brand-name products often returned no results. International foods were largely absent.

The logging interface was minimal — which is great for design aesthetics but frustrating when you need to log a complex meal. Adding multiple food items to a single meal was slow. There was no quick way to log a home-cooked dish with multiple ingredients without searching for each one separately.

I timed myself logging a typical dinner — grilled chicken breast, brown rice, steamed broccoli, and a drizzle of olive oil. It took me just over four minutes. That does not sound terrible in isolation, but three meals and two snacks per day meant 15 to 20 minutes of daily logging time. Over a month, that is nearly 10 hours spent typing food names into a search bar.

No AI Photo or Voice Logging

By the time I was using Simple in mid-2025, several nutrition apps had introduced AI-powered photo recognition and voice logging. Simple had neither. Every entry was manual text search, manual selection, manual portion adjustment. The app's modernity stopped at the visual design layer — underneath, the logging technology was outdated.

I particularly felt the absence of voice logging during breakfast. I am a morning person who eats while getting ready for work. Stopping to type "two eggs scrambled, one slice sourdough toast, half an avocado, coffee with oat milk" into a search interface one item at a time was not realistic. I started skipping breakfast logs, which meant my daily calorie counts were consistently underreported.

Macros Were Present, Micronutrients Were Absent

Simple showed me calories, protein, carbohydrates, and fat for each food entry. That was the extent of the nutritional data. No vitamins. No minerals. No fiber detail. No omega fatty acids. No potassium, magnesium, iron, zinc, or anything else beyond the big four.

For someone doing intermittent fasting, this is a significant gap. When you compress your eating into a six to eight-hour window, every meal needs to deliver more nutritional value per plate. Without micronutrient visibility, I had no way to know whether my shortened eating window was actually providing everything my body needed.

My doctor had flagged low vitamin D and suboptimal magnesium on my last blood test. She asked me to track my dietary intake of both. Simple could not do this. A nutrition app that cannot track vitamins and minerals is like a GPS that shows you the highway but not the exits.

The Barcode Scanner Was Inconsistent

Simple had a barcode scanner, but it missed frequently. I tested it on 15 pantry items over a weekend. It recognized 8, partially recognized 3 (correct product but wrong variety or size), and completely missed 4. A hit rate below 55 percent is not useful enough to be a primary logging method.

The Fasting Timer Was Not Enough to Keep Me

I stayed on Simple longer than I should have because the fasting timer was so good. The visual countdown, the fasting zone indicators, the streak tracking — all excellent. But I eventually realized I was paying eight-plus dollars per month primarily for a timer that my phone's built-in clock app could replace.

The nutritional value I was getting from Simple did not justify the subscription. The food logging was basic, the nutrient data was shallow, and the AI features that modern nutrition apps offered were completely absent.

Why Nutrola Made Sense

I spent a week evaluating alternatives. My requirements were specific:

  1. Detailed micronutrient tracking (at least 30-plus nutrients)
  2. AI-powered logging (photo or voice) to reduce logging time
  3. A large, verified food database
  4. Affordable pricing
  5. No ads or aggressive upsells

Nutrola checked every box. Over 100 nutrients tracked. AI photo recognition, voice logging, and barcode scanning. A database of 1.8 million-plus verified foods. Two euros fifty per month. Zero ads.

I cancelled Simple and signed up for Nutrola on the same day.

The First 40 Days on Nutrola

Week One: Speed and Relief

The first meal I logged on Nutrola was a Buddha bowl I had made for lunch — quinoa, roasted chickpeas, sweet potato, kale, tahini dressing, and pickled onions. On Simple, this would have been a six-item manual search taking about five minutes. On Nutrola, I took a photo, the AI identified the components, I adjusted the chickpea and tahini portions, and confirmed. Total time: about 80 seconds.

I almost did not believe it. I logged the next three meals using different methods — barcode scanning for a packaged snack, voice logging for a quick breakfast, and photo recognition for dinner. Every method was dramatically faster than what I had been doing on Simple.

By the end of week one, my daily logging time had dropped from about 18 minutes to roughly 6 minutes. More importantly, I was logging everything — including the snacks and drinks I had been skipping on Simple because the friction was too high.

Week Two: The Nutrient Awakening

This is when the 100-plus nutrient tracking started to change my perspective.

On Simple, I knew my daily calories and macros. That was the entire picture. On Nutrola, I could suddenly see that my Monday diet was rich in iron but poor in vitamin C (which impairs iron absorption). My Wednesday meals were high in calcium but low in vitamin D (which is needed for calcium absorption). My overall potassium intake was consistently below recommendations.

These nutrient interactions were invisible on Simple. Not because Simple was hiding them, but because it simply did not track them. You cannot see patterns in data that does not exist.

I started making small, informed adjustments. I added a kiwi or orange to meals with iron-rich foods. I made sure my calcium-rich meals included some vitamin D sources. I added a banana or sweet potato to days that were running low on potassium.

These were not dramatic diet overhauls. They were micro-adjustments based on real data. And they would have been impossible without detailed micronutrient tracking.

Weeks Three and Four: Recipe Import and Routine

I meal-prep most Sundays, which means I eat the same lunches and dinners for three to four days in a row. On Simple, I had to log each ingredient every time, or create a rough custom entry that was never quite accurate. On Nutrola, I imported my meal-prep recipes from their original URLs, and the app calculated the per-serving nutrition data for each recipe.

My Sunday meal prep now takes about 10 minutes to log for the entire week. I prep the food, import or select the saved recipes, and set the servings. Done. For the rest of the week, I tap the saved recipe each day. This alone saved me over an hour of logging time per week compared to my Simple workflow.

Smartwatch Logging

I wear an Apple Watch, and Nutrola's watchOS app let me do quick logs from my wrist. This was useful during work meetings when I could not pull out my phone but wanted to log a snack or coffee before I forgot. Simple had no comparable smartwatch feature when I used it.

What I Lost by Leaving Simple

I want to be transparent about what I gave up.

The fasting timer. Simple's fasting timer was beautiful and well-integrated. I replaced it with a free fasting timer app and a recurring alarm on my phone. It works fine, but the experience is not as polished.

The educational content. Simple had well-written articles about fasting science, tips for breaking fasts, and explanations of different fasting protocols. I learned a lot from these early on. Nutrola does not focus on fasting education because it is not a fasting app.

The visual design continuity. Simple is a gorgeous app. The animations, color palette, and overall aesthetic are premium. Nutrola has a clean, functional design that I find pleasant to use, but it does not have the same visual polish as Simple's interface.

None of these were enough to keep me on Simple when the core function I needed — accurate, detailed nutrition tracking — was so much better on Nutrola.

The 40-Day Numbers

Logging time. Simple: approximately 18 minutes per day. Nutrola: approximately 6 minutes per day. That is a 67 percent reduction.

Tracking consistency. Simple: I logged about 70 percent of meals. Nutrola: I log over 95 percent. The difference is almost entirely attributable to faster logging methods.

Nutrients visible. Simple: 4 (calories, protein, carbs, fat). Nutrola: over 100. This is not an incremental improvement — it is an entirely different category of information.

Monthly cost. Simple: 8-12 dollars. Nutrola: 2.50 euros. I save 6-10 dollars per month.

Micronutrient gaps identified. Simple: zero, because micronutrients were not tracked. Nutrola: three significant gaps (vitamin D, magnesium, potassium) identified within the first two weeks.

Who This Switch Is For

If you use Simple exclusively as a fasting timer and have no interest in detailed food logging, Simple is a perfectly good tool. A bit expensive for just a timer, but the design and content are premium.

If you have been trying to use Simple for serious nutrition tracking and feeling frustrated by the limited database, the slow manual logging, and the absence of micronutrient data, you are experiencing a real limitation of the app — not a personal failure.

Simple is a fasting app that happens to have food logging. Nutrola is a nutrition tracking app that does food logging exceptionally well. The difference sounds semantic, but it is the difference between four nutrients and over a hundred, between manual-only logging and AI-powered speed, between an eight-dollar monthly subscription and a two-fifty one.

I still fast. I just no longer pay a premium for a timer to tell me when. And I finally know what is actually in the food I eat during my eating windows. That knowledge, it turned out, was worth far more than any fasting streak.
