Find your place in the sun. SunSeekr shows you where the sun is, right now. Find sunny pubs, cafés, rooftops and restaurants, or use Sun Paths to walk through the sunshine. Our real-time shadow simulation maps sunlight across your city, helping you decide where to sit, where to go and now, how to get there. SUN PATHS Walking navigation, built around sunlight. Pick a start and destination and SunSeekr finds a route that keeps you in the sun, or in the shade when that's what the day calls for.

See the actual shape of a terrace and how much of it is in the sun right now. No more guessing. SUN EXPOSURE BY HOUR Every venue shows when the sun hits, hour by hour. Planning a 4pm drink?

Verdict
The clearest difference is monetization model: SunSeekr at free against Joos's free with in-app purchases. SunSeekr also leads on device support (4 vs 2). Joos's advantage is review sentiment (50% vs 36%) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and iOS requirement there is nothing between them.
