Written by the makers of Glassy. PSTR facts were checked on its US App Store listing on October 30, 2026. This comparison does not claim hands-on performance measurements.
Where PSTR fits
PSTR describes collage templates, adaptive layouts, a background remover and editing tools for posts and wallpapers. If those formats match your routine, its starting layouts may already suit the job. Try a representative project rather than choosing by a feature count.
| Decision | PSTR | Glassy |
|---|---|---|
| Starting point | Templates and adaptive layouts | Themed templates or a continuous canvas |
| Personal details | Not assessed from the listing | Music, lyrics, workouts, routes, weather and places |
| Outputs to evaluate | Collages, carousel posts and wallpapers | Separate slides and scrolling photo video |
| Price | Free with in-app purchases; several subscription offers are listed | Free download; Plus US $4.99/month or $19.99/year |
Where Glassy fits
Glassy is useful when a photo, a line of type and a cutout should continue across the edge of a slide. Start with a template or build the composition yourself, then export the slides in order. If you also want a moving version, export a scrolling video of the canvas. Some materials and formats require Glassy Plus; the app marks the applicable requirement.
For a photo dump about a particular day, use a song or place card to give the pictures context. For a run, use supported Apple Health widgets after granting permission. These are visual layers in your composition. A song card does not add a soundtrack to the export.
Compare the result, not only the editor
- Check whether your opening photo works with the chosen crop.
- Read small type at the size people will see on their phones.
- Review the seam and the order of exported slides.
- Check current regional prices, trial terms and included export options inside the app before subscribing.
