Frequently asked questions
Does solunar fishing actually work?
The evidence is thin and mixed. One recent peer-reviewed study of 361 trout trips found no relationship between popular solunar tables and catch rates. Moonlog does not ask you to believe either side: it compares your catch per hour inside and outside solunar windows on your own trips, with a confidence interval.
How many trips do I need before the Moon Test says something?
Around 30 finished trips is a reasonable first read. With fewer than 10 the app says it is too early; between 10 and 30 it shows the interval and warns that it is wide.
Is my spot data private?
Yes. Spots and trips are stored only on your device. There is no account, no public map and no feed. When you export spots you can blur the coordinates to about 1 km.
Can I import spots from another app?
Yes. Import GPX, KML or CSV files and export the same formats. Duplicates are skipped and invalid coordinates are rejected with a count.
Is there a hunting mode?
Yes. Log hunts and sightings with the wind direction and stand, and see sightings per hour by wind direction on a wind rose. Moonlog is a log, not a legal reference. Follow local regulations.
Is it free?
The web app is free, without ads or an account. A native app is planned; its price is not decided.
How are solunar windows calculated?
From the moon's position computed on your device (SunCalc). Major windows are 1 hour either side of the moon crossing overhead or underfoot. Minor windows are 30 minutes either side of moonrise and moonset. Tests against an independent ephemeris agree to within a few minutes.
