Top 15 Free Intermittent Fasting Apps (No Subscription Required) for 2026

Intermittent fasting is currently all the rage and has a huge following for extraordinary reasons. Numerous individuals claim that intermittent fasting has helped them get rid of stubborn pounds and lead healthy lives.

The funny thing about the intermittent fasting diet is that it has nothing to do with dieting; rather, it just modifies the timing of your meals rather than what you eat. There are various free intermittent fasting apps that you can use together with an intermittent fasting diet.

• The 16:8 method requires a person to fast every day for 16 hours straight; the remaining 8 hours, or the eating window, are then reserved for eating.

• The 5:2 method requires limiting your calorie intake to 500–600 for the final two days after five days of eating normally.

• The most extreme form of intermittent fasting is one meal per day, during which you fast for 23 hours straight before eating whatever you want.

You can choose from any of these IF variations, but you should also make sure that your diet includes foods that meet the body’s nutritional needs. However, it can be a little challenging to keep track of the calories you consume and when you should eat.
