Best 75-Day Challenge Apps in 2026: Track 75 Hard, 75 Soft, and Custom Resets

The best 75-day challenge app does one thing very well: it helps you follow through when the novelty wears off.

That sounds simple, but most trackers are built for either casual streaks or strict 75 Hard rules. If you want to run 75 Hard, 75 Soft, TONA 75, or a custom reset, the details matter. You need habits that are clear enough to complete today, reminders that reduce forgetfulness, and a progress view that makes the whole 75-day run feel visible.

This guide compares the strongest options for different types of 75-day challenges.

TL;DR: Best 75-Day Challenge Apps

1. TONA: best for customizable 75-day resets, including Soft 75, TONA 75, Hard 75, and custom habits.
2. 75 Hard App: best for people following the official 75 Hard program exactly.
3. Streaks: best for a clean iPhone habit tracker that can support a simple 75-day routine.
4. Habitify: best for people who want a polished general habit tracker across multiple areas of life.
5. Productive: best for coaching-style reminders and habit prompts.
6. Way of Life: best for people who like charts, trend lines, and quick daily logging.
7. Notion or Google Sheets: best free DIY option for people who want total control.

How We Evaluated the Apps

A 75-day challenge has different requirements from a normal habit tracker. A good app should help with the specific pressure points of a long reset:

• Challenge structure: Can you run a clear 75-day challenge rather than a vague streak?
• Habit customization: Can you choose the habits that fit your life?
• Strictness control: Can you decide what happens when a day is missed?
• Daily check-in speed: Can you complete the app interaction quickly?
• Progress visibility: Can you see where you are in the full 75 days?
• Reminder quality: Does the app help you avoid accidental misses?
• Fit for real life: Does it support both beginners and stricter users?

The right pick depends on your challenge style. Someone doing official 75 Hard needs a different tool from someone building a beginner-friendly Soft 75.

Quick Comparison Table

1. TONA

Best for: People who want a 75-day reset that can be strict, soft, or fully customized.

TONA is built around the 75-day reset format. You choose a preset, customize your habits, then check in each day. The app supports Soft 75, TONA 75, Hard 75, and custom resets, so it fits people who want the challenge container without forcing one fixed rule set.

The preset options are useful because they solve the most common starting problem: choosing rules that are ambitious enough to matter and realistic enough to repeat.

TONA presets include:

• Soft 75: 7,000 steps, 2,000 ml of water, clean eating, and 20 minutes of movement.
• TONA 75: 10,000 steps, 2,500 ml of water, clean eating, and a 30-minute workout.
• Hard 75: 12,000 steps, 3,000 ml of water, clean eating, a 45-minute workout, a progress photo, and weight logging.
• Custom Reset: 3 to 15 habits from categories like Move, Fuel, Grow, Reflect, and Connect.

The missed-day policy is the key difference. Soft 75, TONA 75, and Custom Reset let you keep going after an imperfect day. Hard 75 ends the run when a past day is incomplete. That makes TONA useful whether you want momentum or a strict contract.

What works

• Built for 75-day challenges from the start.
• Supports beginner, balanced, strict, and custom resets.
• Lets you customize habits and targets.
• Covers fitness, hydration, nutrition, reading, reflection, and connection habits.
• Clear missed-day policy, so you know whether your reset continues or restarts.

Limitations

• Best fit for people who want a 75-day reset, rather than a broad productivity suite.
• People following the official 75 Hard rules exactly may prefer the official 75 Hard App.

2. 75 Hard App

Best for: People who want to follow the official 75 Hard program as written.

The 75 Hard App is the official app for Andy Frisella's 75 Hard program. It is designed around the strict version of the challenge: complete every task every day, or start again.

That makes it a strong pick if you already know you want the original 75 Hard rules. It supports the exact spirit of the program, including progress photos, reminders, and daily task completion.

What works

• Official fit for 75 Hard.
• Built for strict daily accountability.
• Progress photos and reminders match the challenge.
• Simple for people who want one clear protocol.

Limitations

• Less flexible if you want a Soft 75, custom reset, or beginner version.
• The strict reset rule can be motivating for some users and discouraging for others.

3. Streaks

Best for: iPhone users who want a clean, minimal habit tracker.

Streaks is a polished habit tracker with a simple interface and strong iOS fit. If your 75-day challenge has only a few habits, you can set them up manually and use Streaks to keep the chain visible.

It is strongest when your challenge is simple: steps, water, workout, reading, or a binary yes-or-no habit. It is less specialized for 75-day resets, so you will need to create the structure yourself.

What works

• Clean, fast daily check-ins.
• Strong fit for Apple users.
• Good for simple habits and visible streaks.
• Flexible enough for a lightweight Soft 75 setup.

Limitations

• The 75-day challenge structure is manual.
• Missed-day rules and challenge intensity are up to you to manage.

Streaks

4. Habitify

Best for: People who want a general habit tracker with more organization.

Habitify is a broader habit tracker that can handle multiple routines, categories, reminders, and progress views. It can work well if your 75-day reset is part of a larger habit system.

The tradeoff is setup. A general-purpose tracker gives you flexibility, but you need to define the challenge yourself. That means choosing the rules, deciding what counts, and tracking the day count with enough discipline.

What works

• Good for organizing many habits.
• Useful if you track routines beyond the 75-day challenge.
• Strong general habit-tracking structure.
• Flexible enough for custom challenges.

Limitations

• Requires manual setup for a 75-day reset.
• Can feel broader than necessary if your only goal is finishing one challenge.

Habitify

5. Productive

Best for: People who like coaching-style reminders and habit suggestions.

Productive is a habit tracker with a more guided feel. It can help if you want prompts, reminders, and a polished habit-building experience rather than a blank checklist.

For a 75-day challenge, it works best when your routine is flexible and behavior-focused. If you need exact 75 Hard rules, progress photos, or a strict reset policy, you may need a more specialized app.

What works

• Friendly habit-building experience.
• Useful reminders and prompts.
• Good fit for people who want help getting started.
• Works for everyday routines that support a challenge.

Limitations

• The 75-day structure is manual.
• May feel too general for strict challenge tracking.

Productive

6. Way of Life

Best for: People who want to spot patterns in their consistency.

Way of Life is built around quick logging and trend visibility. That makes it useful for people who want to understand which habits slip, which days are hardest, and whether the routine is improving over time.

It is less about the drama of a 75-day challenge and more about pattern recognition. That can be exactly what you need if your goal is learning why your habits break.

What works

• Fast daily logging.
• Good charts and trend feedback.
• Helpful for noticing patterns over time.
• Flexible enough for custom habits.

Limitations

• You create the 75-day structure yourself.
• Less built around challenge identity, share cards, or preset routines.

7. Notion or Google Sheets

Best for: People who want a free, fully custom tracker.

A spreadsheet can work surprisingly well for a 75-day challenge. Create 75 rows, list your daily habits as columns, and check each box at the end of the day.

This option gives you total control. You can add formulas, notes, colors, weekly reviews, and custom scoring. It also creates more friction. You need to build the tracker, remember to use it, and manage reminders separately.

What works

• Free or low-cost.
• Completely customizable.
• Easy to adapt for unusual rules.
• Great for people who already live in Notion or spreadsheets.

Limitations

• No built-in challenge experience.
• No native habit reminders unless you add them elsewhere.
• Easier to abandon if the setup becomes messy.

Which 75-Day Challenge App Should You Choose?

Choose based on the challenge you are actually trying to complete.

• Choose TONA if you want a 75-day reset with presets, custom habits, and a missed-day policy that can be soft or strict.
• Choose 75 Hard App if you want the official 75 Hard experience and plan to follow the original rules exactly.
• Choose Streaks if you want a clean iPhone habit tracker for a simple routine.
• Choose Habitify if you want a broader habit system across multiple life areas.
• Choose Productive if you want guided prompts and reminders.
• Choose Way of Life if charts and pattern tracking keep you honest.
• Choose Notion or Google Sheets if you want the most flexible free option.

If you are still choosing between challenge styles, start with 75 Hard vs 75 Soft. If you want the rules behind the original challenge, read what is the 75 Hard challenge. If your bigger problem is consistency, our guide to building a daily routine that sticks will help you design the habits before you pick the tracker.

The Bottom Line

The best 75-day challenge app is the one that matches your tolerance for strictness.

If you want the official 75 Hard contract, use the official 75 Hard App. If you want a 75-day challenge that can start soft, grow harder, or adapt to your real life, TONA is built for that reset. The goal is the same either way: 75 days of visible evidence that you can follow through.
