21-Day Fast
Ananke Apps
21-Day Fast
An offline companion for Christian prayer and fasting. Keep a Daniel Fast, a Lent fast, or a custom fast, with one King James reading a day, a private journal, and a searchable food checker. The app follows your phone’s language: English, Spanish (Reina-Valera 1909 readings) or Brazilian Portuguese.
The app is free to use (US$0 / KSh 0). Fast Pass is optional, from about US$19.99 a year (about KSh 2,596 a year). Prices in full below.
What’s in the free app
- Daniel Fast (21 days), Lent (40 days; Ash Wednesday defaults to 10 February 2027), or a custom fast of 1 to 40 days.
- Start-date shortcuts for today, tomorrow, a 4 January church fast, and Ash Wednesday.
- A progress ring, countdown, streak and day grid on the Home screen.
- A daily check-in, a public-domain KJV passage with a prayer prompt, and a private journal entry that stays on the phone.
- A searchable checker of 240 foods, each marked Allowed, Avoid, or Check label, with a one-line reason.
- One optional daily reminder, scheduled on the device. Large, Larger or Largest text.
- No ads, no analytics, and no account. After install, the app works offline except when you buy or restore Fast Pass through Google Play.
The food checker follows Daniel 1:12 and 10:2–3 and common Daniel Fast guidelines: plants, whole grains, legumes, nuts and seeds, and water; no meat, dairy, eggs, sweeteners, leavened or refined grains, deep-fried foods, solid fats, caffeine or alcohol. Churches differ, so follow your pastor’s guidance.
En español — Ayuno Cristiano 21 Días
Si el teléfono está en español, la aplicación se muestra en español: el nombre en el menú es «Ayuno Cristiano 21 Días», las lecturas diarias son de la Biblia Reina-Valera 1909 (dominio público) y la consulta de 240 alimentos usa nombres y notas en español de América Latina. El diario, las marcas y los ajustes se quedan en el teléfono, igual que en la edición en inglés.
El Pase de ayuno es opcional, con los mismos identificadores de producto (fastpass_yearly, alrededor de US$19.99 / KSh 2,596 al año; fastpass_lifetime, alrededor de US$29.99 / KSh 3,896). Google Play fijará el precio cobrado, que puede aparecer en la moneda de su país. La ficha en Google Play está próxima (prueba cerrada).
La misma consulta de alimentos en la web está disponible en español, gratis (US$0 / KSh 0).
Em português — Jejum de Daniel 21 Dias
Se o telefone estiver em português, o aplicativo aparece em português do Brasil: o nome no menu é «Jejum de Daniel 21 Dias», cada dia tem um título, a referência da passagem e uma oração, e a consulta de 240 alimentos usa nomes e notas em português brasileiro.
Esta edição não inclui o texto bíblico. Abra a passagem do dia na sua Bíblia — por exemplo a Almeida de 1911, que é de domínio público, ou a tradução que a sua igreja usa. O diário, as marcações e os ajustes ficam no telefone, como na edição em inglês.
O Passe de Jejum é opcional, com os mesmos identificadores de produto (fastpass_yearly, cerca de US$19.99 / KSh 2,596 por ano; fastpass_lifetime, cerca de US$29.99 / KSh 3,896). O Google Play vai definir o preço cobrado, que pode aparecer em reais. A ficha no Google Play está em breve (teste fechado).

Questions
Is the app free?
Yes. The Daniel Fast, Lent and custom fasts, daily readings, the food checker and the journal are free (US$0 / KSh 0). Fast Pass is optional, at the prices above.
When can I get it on Google Play?
The Play listing is coming soon (closed testing). It is not in the public store yet, so there is no Play link to open.
Does it collect my data?
No. Your fast, check-ins, intention, journal and settings stay on the phone and are left out of Android cloud backup. Uninstalling the app deletes them. The privacy policy is on this site.
Is this medical advice?
No. It is a guide for spiritual practice, not medical advice. Talk with your doctor before changing how you eat, especially if you are pregnant or nursing, diabetic, have a health condition, or take medication. The app does not make health or weight-loss claims, and it does not track calories or weight.
Is it available in other languages?
Yes. The app follows the phone. In Spanish you get “Ayuno Cristiano 21 Días” and daily readings from the Reina-Valera 1909 (public domain). In Brazilian Portuguese you get “Jejum de Daniel 21 Dias”: titles, references and prayers, but not the verse text itself — open each passage in your own Bible. The web food checker is also in English, Spanish and Portuguese (US$0 / KSh 0).
