Intermittent fasting has settled into the mainstream, and two apps consistently come up when people search for a digital fasting companion: Fastic and Simple. Both promise to make time-restricted eating easier to stick with, but they take noticeably different approaches. Fastic leans on a friendly fasting timer, meal inspiration, and habit-building features, while Simple positions itself as a fasting-first coach built around an AI assistant named Avo and a food quality scoring system. If you are typing fastic vs simple into Google, you probably want a straight answer: which one fits the way you actually live? The honest response is that it depends on whether you want a lightweight timer with extras or a more guided, coach-style experience. In this post we walk through what each app offers based on their App Store listings and official websites, compare them feature by feature, and finish with a verdict organized by use case rather than a single winner. This comparison is based on publicly available information as of July 27, 2026. Features and pricing may change. We encourage readers to try the apps to find what works best for them.

What Fastic and Simple Each Offer Out of the Box
Fastic, according to its website and App Store listing, is built around a central fasting timer that tracks your eating and fasting windows across popular protocols like 16:8, 18:6, and longer fasts. Around that core, Fastic layers in water tracking, step counting integration, meal inspiration with recipe ideas, and gamified streaks designed to keep you engaged day after day. There is a free tier that covers the essential timer and tracking, plus a paid Plus subscription that unlocks the fuller coaching content, recipes, and advanced features. For someone who mainly wants to know when their window opens and closes, the free version of Fastic covers a lot of ground, which is genuinely one of its strengths compared to subscription-only rivals. Simple takes a different angle. Based on publicly available information, Simple is a subscription-based fasting app that pairs its timer with an AI assistant called Avo, which answers questions, nudges you through your fast, and reacts to what you log. Instead of counting every calorie, Simple uses a food quality scoring approach: you log what you ate, and the app scores how well it supports your fasting and health goals. That makes logging faster than traditional gram-by-gram tracking, and it appeals to people who find full calorie counting tedious. Simple also generates personalized plans from an onboarding quiz, adjusting fasting protocols to your schedule, activity, and goals. The philosophical difference matters more than any single feature. Fastic feels like a toolkit you drive yourself, with optional paid coaching on top. Simple feels like a coach that happens to include a timer, and as of this writing it expects a subscription to get the real experience. Neither approach is wrong; they simply suit different personalities.
Fastic vs Simple Head to Head: Timers, Coaching, Food Logging, and Price
On the fasting timer itself, the two apps are close to interchangeable. Both support the common protocols, both send notifications when your window opens and closes, and both visualize what your body is theoretically doing during a fast. If all you need is a reliable timer, either app handles it, and Fastic arguably wins on value because its timer sits in the free tier. Coaching is where they diverge. Simple's Avo assistant is the headline feature, offering conversational answers about hunger, cravings, what breaks a fast, and how to adjust your plan. According to Simple's website, Avo draws on your logged data to make its guidance feel personal. Fastic offers educational content, challenges, and structured programs in its Plus tier, but it is more of a content library plus habit system than a conversational coach. If you know you respond well to interactive back-and-forth guidance, Simple has the edge here based on publicly available descriptions. Food logging is another meaningful split. Fastic includes meal inspiration and lets you snap or note meals, but it is not primarily a nutrition tracker. Simple's food scoring gives you fast, low-friction feedback on food quality without demanding exact portions, which many reviewers describe as a relief compared to traditional calorie counting, though people who want precise macros may find it too loose. On pricing, Fastic offers a functional free tier with a Plus upgrade, while Simple is effectively subscription-first with a trial, so budget-conscious users will notice the difference immediately. Exact prices vary by region and promotion, so check each app's current listing before deciding.
Which Fasting App Should You Choose in 2026? A Verdict by Use Case
Choose Fastic if you want a free or low-cost fasting timer with pleasant extras. It is a strong pick for self-directed people who already understand intermittent fasting and mainly need structure, reminders, and a bit of motivation. The gamified streaks and water tracking make it easy to build the habit, and you can stay on the free tier indefinitely if the essentials are enough. Choose Simple if you want to be guided. First-time fasters, people who have quit fasting before because they felt lost, and anyone who likes asking questions in the moment will get more from Avo and the personalized plans. The food quality scoring is also a good middle ground for people who want some nutritional awareness without weighing chicken breasts. The trade-off is cost: you are paying for coaching, and if you never open the chat, you are not getting your money's worth. If your goals extend beyond fasting windows into what you actually eat, it may be worth looking at a dedicated nutrition tracker as well; Intake Nutrition, an AI-powered iOS tracker with photo, voice, and barcode logging plus an AI coach, is a modern option you can try free alongside either fasting app. Whichever direction you go, the best fasting app in 2026 is the one you will still be opening in November. Both Fastic and Simple offer trials or free tiers, so spend a week with each before committing to an annual plan.
