Spirit Fast

What Spirit Fast is

Spirit Fast is a mobile-first Christian fasting tracker. The core loop is: pick a fast (a window like 16:8, a structured program like the Daniel Fast, or a one-off full-day fast), pick or accept the paired Scripture passage and prayer focus, optionally invite a buddy, start the timer, and journal at the end. The app keeps a history of your fasts, your reflections, and the prayer requests you exchanged during them.

It is available on iOS and Android, with no current web or smartwatch version. The free tier is a real product — you can run a 16:8 fast every day for the rest of your life without paying — but the structured programs, the prayer-buddy social layer beyond a couple of contacts, and the full Scripture library sit behind the Premium subscription at roughly $29.99/year.

Why prayer-fasting Christians prefer Spirit Fast

The reason Spirit Fast exists is that the secular fasting apps are excellent at what they do — and what they do is help you lose weight. Open Zero and you see calories saved, fat-burning windows, and weight charts. Open Fastic and you see body measurements and "challenges" that look like Peloton gamification. None of that is bad, but it is the wrong frame for someone fasting because they read Matthew 6:16 or Joel 2:12 and decided to add fasting to their prayer life.

Spirit Fast inverts the defaults. The home screen leads with a verse, not a calorie number. The timer screen shows the prayer focus for this fast, not your ketosis status. The end-of-fast prompt asks what God spoke to you, not how much weight you lost. This sounds like a small thing. In practice it is transformative — because the app is no longer working against the reason you opened it.

Scripture-paired fasts: the differentiator

Every fast in Spirit Fast — whether you pick a 16:8 window or a 21-day breakthrough program — gets paired with a Scripture passage and a short prayer focus. The free tier rotates through a starter set; Premium opens a full library organized by theme (breakthrough, repentance, intercession for a loved one, fasting for direction, fasting before a hard decision, gratitude). You can also choose your own passage if the app’s pick does not fit your week.

The mechanic matters more than it sounds. When the timer pings at hour six and you are tempted to break, the screen you see is not "you have burned X calories" — it is the verse and the prayer focus you set when you started. Users consistently report that the verse anchoring is the feature that actually changes whether they finish a fast, especially the longer ones. It moves fasting from a willpower exercise to a prayer practice, which is the entire point.

Prayer buddies: fasting with other people, on purpose

You can invite friends to fast with you — by phone number, email, or a shareable link — and during the fast you can exchange short prayer requests inside the app. You see when your buddy starts the fast, when they break it, and any prayer notes they choose to share. There is no public feed, no likes, no follower count. It is closer to a private group text than to social media, and that is deliberate.

Why it matters: fasting in isolation is hard, and most Christian writing on fasting from Augustine forward assumes you are doing it with other people. The prayer-buddy layer is what makes Spirit Fast usable for small groups, ministry teams, and married couples who want to fast and pray together without having to coordinate via a separate group chat. For a corporate church fast — the kind a lead pastor calls for the first 21 days of January — the buddy feature is the killer use case.

Structured Christian fasting programs: Daniel Fast, 21-day, and friends

Premium unlocks a growing library of structured programs that codify well-known Christian fasting traditions. The Daniel Fast is the headline one — the 21-day plant-and-water fast drawn from Daniel 1 and 10, with the food rules, the daily Scripture, and a journal prompt pre-loaded for each day. A 21-day breakthrough fast, an Esther Fast (3-day no food and no water, with appropriate cautions), partial-day fasts, sundown-to-sundown fasts, and corporate fast templates round out the set.

For someone who has heard their pastor announce a January Daniel Fast and immediately googled "what can I eat on a Daniel Fast," the value is that the answer is now sitting inside the timer instead of in a half-remembered blog post. The programs are not the deepest in the world — a serious Daniel Fast cookbook will go further on recipes — but as a runway to actually doing the thing, they remove most of the friction.

Pricing

Where Spirit Fast falls behind

No Apple Watch or Wear OS app. For a timer-driven product this is the most felt gap — you check fast progress on your phone, not your wrist, which is a small but real friction during longer fasts. It is on the roadmap based on user replies, but not shipped (yet).

Thin liturgical and Catholic/Orthodox coverage. The Scripture pairings and the structured programs lean broadly evangelical Protestant, with a comfortable home for Pentecostal and Charismatic framings of fasting (breakthrough, intercession, spiritual warfare). Users from liturgical traditions who want Ember Day fasts, Lenten weekday abstinence rules, or Orthodox dietary fasts will need a dedicated Catholic or Orthodox app for that layer.

Smaller social layer than the secular apps. Spirit Fast has a real community, but if your prayer-buddy list is empty and none of your contacts use the app, you may go a week before finding a partner. The product is best when you bring your own people — a small group, a spouse, two friends from church.

Limited health-app integration. Spirit Fast deliberately does not push you toward weight tracking, which is correct for the product’s spirit, but it also means people who do want to monitor blood-sugar trends during a long fast will need a second app. Apple Health and Google Fit support is minimal.

Audio teaching is shallow. There is some introductory audio explaining each program, but nothing like Hallow’s guided audio library or Lectio 365’s daily 10-minute liturgy. Spirit Fast is a fasting tool first; if you want a deep daily audio devotional, you will run it alongside another app.

Spirit Fast vs. Exodus 90 vs. Lent Companion

These three apps all sit in the broader "Christian discipline tracker" neighborhood, but they are aimed at very different users. Spirit Fast is a year-round, broadly evangelical fasting tracker — pick any week, run a 16:8 or a 21-day, pair it with Scripture, fast with a buddy. Exodus 90 is a 90-day Catholic spiritual exercise built around cold showers, no alcohol, no sweets, no recreational screens, and a strict daily prayer and fraternity rhythm, designed to be done once a year (typically leading into Easter). Lent Companion is a season-specific Catholic Lenten devotional and tracker built around the 40 days from Ash Wednesday to Easter.

Different strengths. Spirit Fast is better at flexible, year-round, prayer-anchored intermittent and short-term fasts that fit normal life. Exodus 90 is better at a single high-intensity annual reset done in a brotherhood. Lent Companion is better at walking with the Catholic liturgical calendar through Lent specifically.

A Pentecostal small group running a January 21-day fast will be much happier in Spirit Fast. A Catholic men’s group preparing for Easter will be much happier in Exodus 90. A Catholic family wanting daily Lenten prayer and almsgiving prompts will be much happier in Lent Companion. None of these apps is trying to do the others’ job, and Spirit Fast is the only one of the three a Baptist, non-denominational, or charismatic Christian is likely to find a comfortable home in for ongoing weekly use.
