Simply Fast is a beautifully simple, no-frills companion for time-restricted eating. Rebuilt from the ground up for the latest iPhone and Apple Watch, it keeps the same clean, one-glance design while feeling right at home on today's devices. Set your window, glance at your progress, and get on with your day. [Features] • Clean, distraction-free design for iPhone and Apple Watch. • Set your fasting start time to any half hour of the day. • Choose a fasting duration from 12 to 23 hours. • A live progress bar shows your current fasting or eating window, with the time remaining at a glance. • Apple Watch complications for modern watch faces, so your window is always one look away. • A notification at the start of each fasting and eating window. • Your schedule stays in sync across iPhone and Apple Watch. • No sign-in, no account, no ads, and no pop-ups. • Private by design: the app collects nothing and sends us no information. [Important] You should consult your doctor before starting or changing a fasting schedule. Simply Fast supports time-restricted eating only, not full-day fasting such as 5:2, and it does not track or store a history of your fasts. [Feedback] We would love to hear from you. Please reach us through the app support page (https://www.mpathy.tech/contact-us). If you find Simply Fast useful, please tell a friend and leave a rating on the App Store. Your support keeps the app going.

Verdict
The clearest difference is price: Walk Buddy at Free against Simply Fast's $0.99. Walk Buddy also leads on update cadence (every 4 days vs every 2 months) and rating (4.8 vs 4.5). Simply Fast's advantage is review sentiment (100% vs 80%). On ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Walk Buddy is free to download; Simply Fast costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Walk Buddy holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Walk Buddy has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Simply Fast's written reviews are positive against 80% of Walk Buddy's, so the app with the better star average is not the one people write more warmly about.
Simply Fast ships an update every 2 months, Walk Buddy every 4 days. Both last shipped on November 3, 2026.
