Her 75 vs 75 Soft: Which Challenge Is Right for You?

Her 75 and the 75 Soft Challenge build the same core habits over 75 days — a daily workout, water, reading, and mindful eating. The difference is packaging: Her 75 is a paid app that adapts the challenge specifically for women, while 75 Soft is the original open challenge anyone can follow for free with any tracker. Here's an honest side-by-side so you can pick the right fit.

What is Her 75?

Her 75 is a wellness app that markets the 75-day challenge to women. It packages the familiar daily habits — movement, hydration, reading, mindful eating, and a progress photo — with women-specific guidance like cycle-aware hydration and workout adjustments, and it offers three intensity tiers (a soft, medium, and hard mode). It's free to download, but full access requires a paid subscription (around $15/month at the time of writing).

What is the 75 Soft Challenge?

The 75 Soft Challenge is the original "gentler" 75-day challenge: one 45-minute workout a day (with a weekly active-recovery day), 3 liters of water, 10 pages of reading, healthy-but-flexible eating, and alcohol only on social occasions. Crucially, there is no restart penalty if you miss a day. It isn't tied to any one app or brand — you can follow it with a notebook, a spreadsheet, or a free tracker.

Her 75 vs 75 Soft: side by side

The biggest difference is cost

The daily habits are nearly identical — Her 75's "soft" tier is essentially the 75 Soft Challenge. The real difference is that Her 75 charges a subscription for its guided experience, while the 75 Soft Challenge itself is free to do. If the cycle-aware coaching and in-app structure are worth a monthly fee to you, Her 75 delivers that. If you mainly want to complete the challenge and track your streak, you can do the same thing at no cost.

Do you need the Her 75 app to do 75 Soft?

No. The 75 Soft Challenge belongs to no single app, so you can follow the exact same daily tasks for free. The free Soft75 app lets you check off your workout, water, reading, and healthy eating each day with milestone celebrations and a private, offline-first experience — the same habit-tracking loop, without a subscription.

Adapting 75 Soft to your cycle (for free)

One thing Her 75 gets right is adjusting the challenge to your menstrual cycle — and you can apply the same ideas to 75 Soft yourself:

• Luteal and menstrual phases: swap intense workouts for walks, yoga, or mobility work — all of which count toward your 45 minutes.
• Heavy-flow days: add electrolytes and an extra glass of water alongside your 3-liter goal.
• Follicular phase: lean into higher-intensity sessions when your energy naturally rises.

Because 75 Soft has no rigid workout-type rule, these swaps are fully within the challenge — no paid tier required.

Which should you choose?

Choose Her 75 if you want an app to hand-hold you through cycle-specific adjustments and don't mind paying a subscription for that structure.

Choose the 75 Soft Challenge if you want the same habits and results for free, prefer flexibility over prescribed tiers, and are happy to track your days with a free app.
