Why the number 80? Ever wonder what all those hard-to-track, pesky serving sizes do for you? A day's allotment roughly ends up being 80 Bites. But that's NOT where we are starting. When you use the 80Bites app, you will get a sound and a question at bite 26. WHY? If your stomach were OK, you would FEEL something. Most of you won't feel anything so keep eating; remember, even if you get to 50 Bites, it is just your current marker. Tap the "Bite" button each time you put food in your mouth. For now, forget about beverages. Eat solid food - not soup - for the diagnostics part of the stomach training program. Created by Registered Dietician Meredith Luce RD MS LN and Pilates Expert Joan Breibart, the 80Bites App precedes the 80Bites Program — 12 STEPS developed to downsize hunger — just like Ozempic! Shedding pounds happens automatically when your hunger is tamed. Visit 80Bites.com to subscribe to the 12 STEP Stomach Training program and ditch dieting for good! A message from Sam the Stomach: Hello, Hungry People! It seems that you eat too often, too much, and food is always on your mind. The 80Bites app is designed to help you manage your eating habits. Here's how it works: Grab a plate of food and a beverage (please note, sips don't count). Open the app, take a bite, and hit the BITE button. When you reach your 26th bite, a loud noise will sound. This is your cue to stop. Push your plate away and focus on your stomach. We're not referring to the larger area under your belly button but rather the small sausage-shaped container under your left breast. Can you feel any sensation of fullness? If not, feel free to continue eating. However, make sure to track when you start to feel full. The app's counter goes as high as 99 bites. If you don't reach a sensation of fullness within this limit, perhaps try again at another meal. Remember, a bag of chips doesn't count as a meal. You might be wondering, why 26 and 80? The answer lies in your hormones. The drug Ozempic works by rebalancing your gut hormones that may be out of sync. With 80Bites and Ozempic, which is soon coming in a handy pill form, you can address this issue in a comprehensive manner. Ready to get started? Let's embark on this journey towards better eating habits together.

Verdict

The call

The clearest difference is review sentiment: 80 Bites at 64% against Fasty's 8%. 80 Bites also leads on update cadence (every 2 months vs every 9 months) and iOS requirement (13.0 vs 16.5). Fasty's advantage is price (Free vs $0.99) and rating (4.7 vs 4.1). On ads, in-app purchases, monetization model and device support there is nothing between them.

Fasty is free to download; 80 Bites costs $0.99 up front. 80 Bites sells 1 one-off in-app purchase and Fasty sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Fasty holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Fasty has 1.5K ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 64% of 80 Bites's written reviews are positive against 8% of Fasty's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

80 Bites ships an update every 2 months, Fasty every 9 months. The most recent releases landed on September 19, 2026 and September 24, 2026 respectively.
