## What is Fasten?

Fasten App -  Gives you much more than just an Intermittent Fasting Tracker. 

Weight Tracking
We have enabled this feature so you can track your weight along your IF journey. See any fluctuations, make adjustments, and continue to push yourself to your goal.

Hydration
A convenient way to keep track of your liquid intake. Staying hydrated is key to a successful fast as it keeps you satisfied longer, and also, it helps your body get rid of toxins and water weight.

Keto Mode
See what your body is experiencing during your Fasting window; which will keep you motivated to achieve more. During your fasting state, your body goes through several stages which have different benefits. Maintaining a record on how long, and how often you have entered each state, allows for measurement of full benefits to your health, including a reset of the immune system, cells, and liver detox.

Mood Tracking
Everything you do affects you in one way or another.
Mood tracking and journaling are two of the most powerful practices you can cultivate. When you pause and ask yourself how are you feeling, you can learn how new habits and external situations are affecting you daily, and discover any trends over time.

Healthy Choices & Recipes
These recipes are easy to make, good for your health, and will help you get into a keto stage faster, so you can experience all IF benefits more efficiently.

Apple Health
Yes! You can now connect to Apple Health and keep track of all your apps data in one place.

About Intermittent Fasting.
When you eat, you store energy in the liver as glycogen. But after 10 to 12 of fasting, your glycogen reserves will be deficient, which means you'll start to convert fat into energy for your body and brain. The longer you fast, the more fat you'll burn. It is recommended to start with a 12-hour fasting window, then work your way up to a 14 or 16-hour window.

Intermittent fasting has several benefits for your body:
* Improves mental clarity and concentration
* Helps with weight loss
* Lowers blood insulin and sugar levels
* Reversal of type 2 diabetes
* Increased growth hormone
* Lowers blood cholesterol
* Increases muscle gain
* Slows down aging
* Decreases inflammation
* Reduces the risk of cancer

Ways to do intermittent fasting
- Fast for 12 hours a day - Eating window  12 hours
- Fast for 14 hours day - Eating window 10 hours
- Fast for 16 hours - Eating window - 8 hours
- Fast for 2 days a week: 5:2 methods which you eat less than 500 calories two days a week and eat regularly for the other 5 days.
- Alternate day fasting: Eat regularly for one day and restrict your calorie intake to 500 calories the next day.
- A weekly 24-hour fast: Fast for 24 hours one-day fo the week

Fasting helps you to practice mindfulness meditation and enhances your meditation and yoga practice. For centuries, fasting has been used to improve alertness, concentration, and self-discipline.

### 1/5 — Used to be cool, now can't even access

*2023-02-13, version 3.1*

I have attempted to contact the company, and Apple, I paid for a subscription, and I have not been able to access the app for months and months. I canceled it and will not renew obviously. Disappointed that I wasted money and time. I really did enjoy this app before I don’t know what happened.

### 3/5 — Idea 💡

*2021-05-09, version 2.9*

You send us a reminder to end the fast but you don’t send a reminder to start a fast 💨 that would be an excellent idea to be able to set a timer for every day to start a fast at the same time please

### 2/5 — 👎

*2021-04-14, version 2.9*

This is unreliable.  I will end a fast and ask to save but when I return hours later it acts like I am still fasting.  And constantly encourages me to pay for upgrade.  Why would when I can't trust the free version to track my fasts.  Looking for another alternative

### 5/5 — Great app

*2021-03-03, version 2.8*

Let’s me see the countdown to my fast which is encouraging to me. Works for what I need it for.

### 3/5 — Options

*2021-01-11, version 2.7*

I like the timer but it would be nice if more of the app were usable without fees.

### 2/5 — No data export!

*2020-12-02, version 2.6*

I have been using the app for over a year. It does a good job. Today I tried to figure out how to export my data, but there is no feature for this. Moreover, the user support site is completely blocked off so I can’t even contact the developer to inquire about this. I’m disappointed.

### 5/5 — Great app

*2020-05-06, version 2.4*

Love this app great for IF beginners.

### 3/5 — History comparisons

*2019-11-16, version 2.4*

Nice app. But I’d like to see my history comparison not just the pass 5 days and with just strolling down.

### 3/5 — Disappointed

*2019-11-11, version 2.4*

I enjoy the functions provided however it’s missing two major components.  First, fasts can only be set in hours and cannot be edited mid-fast.  Start time can be changed, but not end time without ending the fast and having to plug in the new timeframe or just waiting it out to go “over” your time (which means no end fast notification).  Do-able, but not convenient.  More importantly, you cannot set recurring fasts.  I generally follow a 23 hour fast protocol daily and therefore would need to set a new custom fast each day.  23hrs doesn’t always happen hence the need for easy editing. It’s a beautiful app but I feel like an app that only manages fasting should have these basic features for ease of use.

### 4/5 — Apple watch please

*2019-10-17, version 2.4*
