The Top 5 Intermittent Fasting Apps for Women — And the One I Told My Best Friend to Download
Intermittent fasting apps have transformed how we approach weight loss and metabolic health, but not all of them deliver real results. We tested the most popular options for fasting guidance, ease of use, and actual outcomes so you don't waste time on the wrong one.

Over the last few years, intermittent fasting has become the go-to approach for women who want to lose weight, boost energy, and improve their health — without obsessing over every calorie or giving up entire food groups.
It's the science-backed eating pattern that focuses on when you eat rather than what you eat — giving your body extended windows to burn stored fat, regulate blood sugar, and reset your metabolism.
When done correctly, the hunger pangs fade, the afternoon energy crashes disappear, and you stop feeling like you're constantly fighting your own body. Your focus sharpens.
And to make matters even better, your metabolism starts working on your schedule instead of against it. This creates a "double benefit" where you're burning fat while actually feeling lighter, clearer, and more in control throughout the day.
tl;dr — Intermittent fasting makes weight loss feel natural.
That's probably why, in recent years, doctors and wellness researchers have been recommending intermittent fasting for everything from insulin resistance to hormonal weight gain in women over 35.
Thousands of women have transformed their bodies and energy levels through consistent fasting. But sticking with it used to mean guessing at fasting windows, white-knuckling through hunger, and hoping you were doing it right with zero guidance.
Thankfully, a new wave of intermittent fasting apps has made it easier, more structured, and more supportive to follow a personalized fasting plan — without the confusion, the willpower battles, or the feeling of doing it all alone.
But with all the apps flooding the market, which ones actually work? That's exactly what we investigated.
Our team reviewed dozens of intermittent fasting apps and narrowed them down to the five most popular options. Then we compared them for fasting guidance, user experience, personalization, and most importantly… real-world weight loss results.
Here's what we found...
How We Ranked These Apps
We scored each app on four critical factors:
Fasting Guidance Quality: Does the app offer structured fasting protocols with clear explanations, smart timers, and expert-backed scheduling — not just a countdown clock?
User Experience & Design: Is the app intuitive, with easy navigation, helpful reminders, and useful progress tracking?
Personalization: Does the app adapt to your age, lifestyle, metabolism, and wellness goals, or is it one-size-fits-all?
Real Results: Are actual users experiencing meaningful improvements in weight loss, energy, cravings, and overall well-being?

THE COMPLETE BREAKDOWN
Out of every intermittent fasting app we reviewed, Reverse Health was clearly different. From the very first week, it left the other apps in the dust.
Our testers consistently reported fewer cravings, more stable energy throughout the day, and noticeable fat loss — especially around the midsection where hormonal weight tends to settle. As the weeks went on, many experienced less bloating, better sleep, and a clearer head.
And it all happened without extreme restriction. Just follow the personalized fasting and nutrition plan and let the program guide you. Multiple testers described this experience as “the first time fasting actually clicked.”
Most telling of all… most of our testers continued using the app after the test period was over. This wasn’t true for any other app on the list. Only Reverse Health.
The difference came down to more than just a fasting timer — Reverse Health’s program is a complete metabolic support system, specifically designed for women over 35, and built around science that accounts for hormonal shifts, perimenopause, age-related metabolism changes, and real-life schedules.
In short: If you want the app that checks every box for structured fasting, personalization, and real results, Reverse Health is the clear winner.
Why it’s #1
Hormone-Aware Fasting Plans — Unlike generic fasting timers, Reverse Health understands how perimenopause, cortisol, and insulin resistance affect fat storage and metabolism in women over 35
Personalized Fasting & Nutrition Program — After a quick quiz, you receive a customized plan based on your age, lifestyle, metabolic profile, and health goals — including both fasting schedules and balanced eating guidance
Expert-Led Guidance — Certified nutritionists and wellness coaches designed every element of the program to work with your body’s natural rhythm, not against it
Holistic Wellness Support — Beyond fasting windows, the app includes movement routines, mindfulness practices, habit tracking, and a supportive community of 70,000+ women
Beginner-Friendly Progression — The program eases you into fasting gradually, making it perfect for complete beginners while still effective enough for women who’ve tried fasting before without lasting results

PROS
- Most comprehensive fasting and nutrition program in the category
- Designed specifically for women's hormonal and metabolic needs after 35
- Includes coaching, movement routines, mindfulness, and community support
- Sustainable approach — no extreme restriction or burnout
- Thousands of women report outstanding fat loss and energy results
- Educational content explains the science behind every recommendation
CONS
- Requires internet connection for HD video content
Our experience: Testers reported reduced cravings and more stable energy within the first week, with visible fat loss becoming noticeable by week two. Over the full program, bloating decreased dramatically, clothes fit better, sleep improved, and the daily fasting rhythm became second nature rather than a struggle.
Bottom line: Reverse Health offers the strongest combination of expert-backed fasting guidance, personalization, and holistic support. The results speak for themselves. Reverse Health Intermittent Fasting Program is the clear winner, hands down.
#2 — Zero Intermittent Fasting Tracker
Overall Grade B+
Overall Grade
B+
Rating
8.8/10
THE COMPLETE BREAKDOWN
Zero is one of the most widely used intermittent fasting apps on the market, with over 12 million users globally. The app is built around flexibility — users can choose from a variety of fasting protocols including 16:8, 18:6, 5:2, OMAD, and custom fasts tailored to their lifestyle.
Where Zero shines is its commitment to science-backed education. The app includes expert-led content from medical advisors and researchers covering topics like autophagy, insulin sensitivity, and metabolic function. As users log weight, mood, and activity, the app provides personalized insights and trend reports.
However, Zero is primarily a tracking and education tool, not a guided program. There’s no integrated meal planning, no coaching, and no hormone-aware personalization. It’s an excellent companion for self-directed fasters who already understand what they’re doing — but not the best choice for women who want structured, done-for-you guidance.

- Personalized trend analysis and insights
CONS
- No integrated meal planning or food logging
- Advanced metrics locked behind paid version
- No personalized coaching or guided programming
Verdict: A powerful tracking tool for experienced fasters, but not the best option if you want a structured, guided program designed for your body and goals.
#3 — Simple Intermittent Fasting App
Overall Grade B
Overall Grade
B
Rating
8.3/10
THE COMPLETE BREAKDOWN
Simple takes a habit-first approach to intermittent fasting, using behavioral science and micro-coaching to help users ease into fasting with small, achievable steps. After a quick onboarding quiz, users are matched with a fasting protocol suited to their lifestyle — typically a variation of 16:8 or 14:10.
The app includes a real-time fasting tracker, hydration reminders, and mood and energy logging. Daily articles, recipe ideas, and wellness tips are written in plain, relatable language. The premium plan unlocks deeper insights and access to a health coach.
However, Simple lacks the depth of personalization found in top-tier programs. There’s no hormone-aware guidance, no integration with wearables, and the coaching feels more like general wellness tips than a structured metabolic support system. It’s a solid starting point for beginners, but limited for women who need a program that adapts to their specific biology.

CONS
- Some advanced features require a subscription
- No integration with wearables
- Less suitable for advanced fasters or women with hormonal weight challenges
Verdict: A friendly, approachable entry point for fasting newcomers, but lacks the depth and metabolic intelligence that women over 35 need for lasting results.
#4 — Lasta Intermittent Fasting & Mindful Eating App
Overall Grade C+
Overall Grade
C+
Rating
7.8/10
THE COMPLETE BREAKDOWN
Lasta combines intermittent fasting with a psychology-first approach to wellness, making it a unique choice for women who struggle with emotional eating alongside weight management. In addition to personalized fasting schedules, the app provides daily CBT-based lessons, journaling prompts, and breathing exercises designed to build a healthier relationship with food.
The onboarding process assesses eating patterns, stress levels, and goals, then generates a tailored program combining fasting, nutrition tips, and mindfulness techniques. The interface is minimal and calming — ideal for users overwhelmed by overly technical apps.
However, the fasting guidance itself feels secondary to the mindfulness features. Women looking for structured metabolic support, hormone-aware scheduling, or deep fasting analytics will find it lacking. It’s a meaningful tool for emotional eaters, but not comprehensive enough as a standalone fasting program.

Verdict: A thoughtful option for emotional eaters who want mindfulness support, but not deep enough for women seeking a complete, results-driven fasting program.
#5 — BodyFast Personalized Intermittent Fasting Coach
Overall Grade C
Overall Grade
C
Rating
7.5/10
THE COMPLETE BREAKDOWN
BodyFast is a well-established fasting app with over 30 million downloads, built around an AI-powered “Coach” that dynamically adjusts your fasting schedule each week based on your goals and progress. The app supports all major fasting methods — from 16:8 and 5:2 to OMAD and alternate-day fasting.
The interface is clean and offers water tracking, weight logging, and weekly challenges to maintain motivation. For users who upgrade to the paid Coach, the app delivers more personalized scheduling, reminders, and health tips.
However, the personalization feels surface-level once you get past the initial setup. The AI Coach adjusts timing but doesn’t account for hormones, age-related metabolism, or the unique challenges women face after 35. Educational content is thin, and there’s no nutritional guidance or mindfulness support built into the program.

CONS
- Requires subscription for full personalized features
- No hormone-aware guidance or nutritional support
- Less emphasis on holistic wellness or emotional eating
Verdict: A decent scheduling tool for general fasters, but too shallow for women who need a program that understands their metabolism, hormones, and real-life challenges.
Why Reverse Health Took the #1 Spot
While other apps offer pieces of the fasting puzzle, Reverse Health brings them all together in one expertly designed program:
The Right Guidance — A complete fasting and nutrition framework designed by certified experts who understand female metabolism

Why You Should Choose Fasting Apps Over Traditional Dieting
Traditional diets require constant calorie counting, rigid meal rules, and expensive programs — leaving you stressed and obsessing over food before you even see results.
On top of that, restrictive eating plans and confusing macro calculations can make healthy living feel impossible, triggering frustration instead of fat loss.
Fasting apps work with your body’s natural rhythm, allowing you to follow a personalized schedule at home, at your own pace, with expert guidance — no deprivation, no confusion, just smarter timing.
