Most IF apps are pure timers. Most calorie counters either don’t ship fasting at all, or gate it behind their highest paid tier. So serious fasters end up juggling two apps — a fasting tracker AND a food logger — that don’t talk to each other.
Swoodie added intermittent fasting in v1.4 with the same six protocols Zero and Fastic use. The tracker is free. Coach quips from Ollie inside your fasting window and Fast Together (pair up with a friend or partner and follow each other’s fast live) are Premium. All of it lives in the same app as your recipe library, calorie tracking, meal planner and couples mode.
Pain points Swoodie addresses
- Juggling a fasting timer app + a calorie counter app that don’t talk to each other
- The fasting timer itself gated behind a Plus / Pro tier
- No social accountability — fasting solo is hard to stick with for more than a week
- Window-open and window-close reminders scattered across phone apps that don’t sync
- OMAD and longer protocols offered with no safety nudges or “talk to a professional” reminder

Fasting tracker + meal tracking in one app
Log meals as you eat them and see the live fasting timer in the same dashboard. No second app to open. Free tier.
Step Counter
Connect Apple Health or Health Connect so your daily steps add calories to your goal — useful for filling your eating window with the right amount of food.
Ready-made diet plans
Load a curated 7-day plan into your planner and tweak it to taste, so your eating window always has a meal lined up.
Six protocols, all free
12:12, 14:10, 16:8 (the most popular), 18:6, OMAD or set your own. The tracker is free; only Coach quips and Fast Together hosting are Premium.
Fast Together — follow a partner’s fast live
Pair up with a friend or partner and see their fast as it runs — their protocol, when they started, how long they’ve been in, refreshed as you watch. Send a 👏 when they need it. You each keep your own protocol. Lite or Premium to host, free to join — same model as Nest.
Window-open and window-close reminders
Opt-in push notifications scheduled around your protocol. No more checking a separate app to know if you can eat.
Fasting Coach (Ollie quips)
Gentle nudges and milestone celebrations as you progress through a window. Premium. The OMAD preset ships with a “talk to a professional” caution.
Wellness Circles
Fast alongside a small group of 3–5 with a shared streak, so nobody breaks their window alone.
Swoodie Moments
Share your breaking-fast meal with friends who fast too — a private feed for accountability and ideas.
Text-to-Nutrition
When your window opens, type what you ate and get calories and macros instantly — no scanning each item.

Start your first fasting window today
Download Swoodie, pick a protocol that fits your day (16:8 is the most common starting point), and the live timer is on. If your partner is fasting too, send them a Fast Together invite and you’ll each be able to see how the other is doing — on your own protocols. The tracker is free; you only need Premium if you want Coach quips inside the window or if you want to host the pairing.
