Public flavor
A faithful rewrite of the 2012 Java original: static prayer text, legacy UTF-8 file layout, and extras parked at the end where the original expected them.
Flutter Hebrew prayer app
A siddur that opens to the right day.
AndDaaven is a Flutter davening app with two compile-time flavors: a faithful public rewrite of the old Java app, and a personal version that adjusts prayer text by date, location, sunset, and explicit section rules.

The runtime engine deletes sections that do not apply; it does not reorder the personal prayer files.
Designed around liturgical rules, not toggles.
Personal flavor
Date and location aware, with sunset detection, dynamic prayer text, Sefiras HaOmer screen, and a test date bar for validation.
Maximum-order files
Personal prayer files are arranged in maximum liturgical order so the app can delete irrelevant sections without inserting or reordering text.
Source-backed behavior
Files that matter
- section_rules.dart
- tefilla_data.dart
- structured_tefilla_loader.dart
- dynamic_text_processor.dart
Calendar machinery
- Hebrew date arithmetic
- GPS and USNO sunset service
- Personal version assets
- Public UTF-8 assets
Text handling is intentionally conservative
Delete-only rendering
The personal flavor’s source files carry every conditional section in its correct place. Runtime logic removes sections that do not apply.
Inline markers
The dynamic text processor handles conditional inline text such as positive and negative conditions without moving whole sections around.
Testing calendar states
The personal flavor includes a test date bar because Rosh Chodesh, Chol HaMoed, and Sefira behavior need deliberate inspection.
Public build
- Static prayer text
- Legacy file layout
- Faithful rewrite goal
Personal build
- Sunset-adjusted date
- GPS-backed location
- Dynamic section filtering
Why the implementation is careful
Liturgical order
- Sections stay in source order
- Runtime deletes only
- Rules stay centralized
Calendar validation
- Sunset changes date
- Rosh Chodesh and Chol HaMoed matter
- Sefira has its own screen
