Sastro reads your birth chart against today's sky and turns it into a working plan: the hours you are most likely to be at your best, what suits the day, and the one thing to leave alone.
It does not predict what any social platform will do with your posts. Nobody can see inside those systems, and an app claiming otherwise is guessing. Sastro describes your rhythm — when you are most willing to be on camera, most likely to write well, most inclined to go back through your archive — which is something you can check against your own experience.
It also has no connection to your accounts. It cannot see your posts, your followers or your analytics, and it never asks you to log in anywhere.
Yes, and plenty of people are in the same position. Choose "I don't know my birth time" during setup. You still get the planetary hours, the Moon's sign, the phase, retrogrades and four of the eight Blueprint readings.
What you lose is the houses, which is where a lot of the day-to-day detail comes from. Those readings are left out rather than guessed at. If you find your birth time later — it is usually on your birth certificate — add it from Settings and the app gets noticeably sharper.
The bundled city list covers places above roughly 15,000 people, so smaller towns are missing. Pick the nearest city that is listed. The time zone and coordinates will be near-identical and your chart will not meaningfully change.
Tap any hour on the Today timeline and you get a straight verdict for that hour — Peak, Good, Fine or Skip. The app is designed never to leave you with nothing useful to do.
Some hours genuinely suit other work better. A Saturn hour is for editing, culling and planning rather than publishing. An app where every hour is fine would not be worth opening.
Sastro does not treat it as dead time. The traditional reading of a retrograde is the "re-" prefix — revisit, revise, revive — so the app points you at your archive: repurpose, re-cut something that worked, fix your bio. It will advise against launching or signing anything during that window.
Check Settings → What you make. Every instruction is phrased for your medium, so a photographer and a podcaster get different wording from the same planetary hour. Change it there and the whole app re-reads immediately.
Yes. Settings → Show the astrology hides the small reason lines. The advice itself does not change — the app still works out every recommendation the same way, it just stops showing the reasoning.
Settings → Theme. Auto follows your device. Sastro is designed for dark, but both work.
The Wardrobe section, in the same subscription, turns the same chart into what to wear: the day’s colour, metal and fabric, outfits built from the clothes you add to your closet, and the best days to buy.
