Best apps to quit junk food and sugar in 2026

Last updated October 20, 2026

Quitting junk food rarely works as a single decision. It works as a count: three days without fast food, then ten, then thirty. A tracker makes that count visible.

We compared 6 iPhone apps that can track junk food or sugar, based on each App Store listing as of October 2026.

The 6 best picks at a glance

How we picked

• A counter for days without junk food or sugar.
• An option to cut down rather than stop.
• A way to track the replacement habit.
• Pattern tracking to see when cravings win.

1. HabitLuma: best for a junk-food-free streak plus a replacement habit

Create a quit habit called no junk food and a build habit for what replaces it, such as cooking dinner at home. Quitting and building habits sit in separate sections of the same home screen.

• Two habit types: quit habits count clean time since your last slip, and build habits use check-ins on the days you choose.
• A slip goes through a short logging flow and restarts the counter. Your earlier runs stay in your history.
• Milestones run up to a year and beyond, and the app marks them automatically.
• Shareable progress cards in portrait, square or story formats.

Pricing: Free download. Pro is $4.99 a month, $24.99 a year or $59.99 once (US prices, October 2026). View HabitLuma on the App Store

2. Quitzilla: best for money saved

Quitzilla lists junk food and sugar among its target habits and shows the money you save by skipping them.

• Tracks several habits at once, each with its own abstinence timer.
• Shows money and time saved, and turns savings into rewards.
• Per-habit statistics, including longest and average abstinence periods.
• A list of your personal reasons for quitting, plus a daily quote.

Pricing: Free with paid plans, listed at $29.99 a year or $89.99 lifetime in the US. View Quitzilla on the App Store

3. HabitKit: best for cutting down

HabitKit's daily maximum lets you cap sugary drinks at one a day before you stop completely.

• Supports quit habits that count clean days, with an optional daily maximum.
• Shows each habit as a grid of tiles, one square per completed day.
• Tracks yes or no, counts, or measured amounts with custom units.

Pricing: Free for up to 4 habits. Pro is sold monthly, yearly or as a lifetime purchase. View HabitKit on the App Store

4. Way of Life: best for spotting trigger days

Way of Life's day-of-week chart shows which days you slip most, such as weekends.

• Marks each day green for a good day or red for a bad day.
• Chains of good days, plus red chains for runs of bad days.
• Pie charts, bar graphs with trend lines and a day-of-week breakdown.

Pricing: Free with a habit limit. Premium unlocks unlimited habits. View Way of Life on the App Store

5. Streaks: best for Apple Health users

Streaks can read Health data to complete tasks automatically, which pairs well with a daily step goal while you quit junk food.

• Reads Apple Health data, with your permission, to complete tasks automatically.
• Negative tasks let you track habits you want to break.
• Tracks up to 24 tasks, each with its own repeat schedule.
• Apple Watch app with complications, plus Home Screen widgets and Siri Shortcuts.

Pricing: Paid app with a one-time price. Check the App Store for the price in your country. View Streaks on the App Store

6. Daylio: best for linking food and mood

Daylio logs mood next to activities, so you can see whether a junk food day follows a stressful one.

• Logs mood and activities with icons, so you never have to type.
• Charts, a calendar and a Year in Pixels view.
• Daily, weekly or monthly goals for habit building.

Pricing: Free with an optional Premium upgrade. View Daylio on the App Store

• If saving money motivates you, choose Quitzilla.
• If you want to cut down first, choose HabitKit.
• If stress drives your cravings, try Daylio alongside your tracker.

Whichever app you pick, start with one habit and log it the moment you do it. Read why tracking your habits matters for what the research says.

Frequently asked questions

What app helps you stop eating junk food?

HabitLuma is the best pick for most people: it counts junk-food-free days and tracks a replacement habit in the same app. Quitzilla adds money saved, and HabitKit helps you cut down with a daily limit.

Should I quit sugar completely or cut down?

Either can work. If quitting completely feels too hard, cut down first with a daily limit, then switch to a clean-day counter.

How do I track days without sugar?

Create a quit habit in an app like HabitLuma and set the start date to your last day with sugar. The app counts the days. If you slip, log it and the counter restarts.
