GeoCrown is a rewards-based social media that uses locations to drive exposure, engagement and influence towards our users.

Users vote for photos at each of these locations to determine who has the best picture at that location. The person with the most votes becomes the cover photo of that location, shown off to everyone in and around that location, up to 250km away! GeoCrown was created by social media users who struggled to build their audience. It didn’t matter how great our posts were, these social media platforms were never created with exposing our posts in mind.

SharpStacker turns a series of night-sky exposures into a single clean, detailed image. By aligning and stacking your shots, it reduces noise and reveals faint detail — stars, the Milky Way and deep-sky objects — that a single frame can't capture. It's built to make astrophotography stacking accessible to everyone: a deliberately simple interface gives you an immediate, intuitive workflow — without the cost or complexity of traditional desktop software. Full RAW support preserves maximum quality from capture to export. The blending mask is generated automatically by a machine-learning model — or drawn by hand — and can be fine-tuned manually for full control. • Full RAW import • Automatic star alignment and stacking • Noise reduction through stacking • ML-generated mask, editable by hand • Simple, immediate workflow • iPhone, iPad and Mac • On-device processing — your photos never leave your device Import your exposures, start the stack, and export a cleaner, more detailed night sky.

Verdict

SharpStacker's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
