Free download, complete casts
Version 1.0.0 is available in HUAWEI AppGallery. The app automatically uses the current system HUAWEI ID and gives new users 3 complete casts. No separate registration or app password is needed.
Only a successfully completed result uses 1 credit. Failure, cancellation and timeout do not. Repeating a cast within the same Chinese hour prompts for confirmation first; viewing, expanding, collapsing and saving history do not use credits.
Ads are always your choice
Choose the home-screen ad button and finish watching: confirmed completion adds 1 credit. Credits can accumulate, with no daily ad-reward limit.
Ads never load or play automatically. There are no splash, banner, interstitial or forced ads. Use your available credits to view a calculation result and its complete process.
Credits sync; history stays on your device
The same HUAWEI ID can sync confirmed credits. History and notes are encrypted on the current device, up to 100 records, and do not sync to a new device.
Calculating requires a connection to verify available credits. The calculation itself runs on the device; existing local history can be viewed offline.
Optional True Solar Time
Enabling True Solar Time requests location once and uses longitude locally to correct time. Raw coordinates are not saved or uploaded; there is no continuous location tracking. Saving history keeps the corrected time and correction minutes locally. Declining location leaves standard-time casting available.
