Shared Projects use a private cloud identity so invited members can collaborate in real time.

Verdict
The clearest difference is in-app purchases: Cosmic Powertech at none against Weeklane's 2. Cosmic Powertech also leads on iOS requirement (13.0 vs 17.6). Weeklane's advantage is update cadence (weekly vs every 8 months). On price, ads and device support there is nothing between them.
