Star Stacker allows you to import a sequence of star photos taken throughout the night and turn them into star trail images or a time lapse video. After importing you can create the images and/or a time-lapse video with a few different effects. - Full trails - every star at full brightness - Faded trails - Stars get brighter as the process runs - Shooting star - Like faded trails but the last image is brighter than any previous giving a shooting star effect - Javelin - Both ends of the trail are faded - Warp mode - zooms into the image stack slowly creating a warped effect. This will also affect the foreground so post processing may be required if the images have the foreground included. You can also choose to save a video of the time-lapse based on the options used for the image stacking. Can import images from your photos app. RAW files that have been recently imported from an SD card reader, may take a few minutes before the full resolution files are available. There are resolution limits depending on the device being used and the memory it has: - 6gb - 62mp - 5gb - 62mp - 4gb - 62mp - 3gb - 42mp - 2gb - 30mp

TempPix is a simple utility that allows you to take quick snapshots and have them stored in a separate, time-limited gallery to avoid littering your main apple photo library with pictures of receipts, shopping items and so on. TempPix is designed to keep quick, lower resolution snapshots and selfies for up to 21 days before being automatically deleted. TempPix can also scan your phone for screenshots, photos from other apps that might be temporary and intelligently "sweep" them into the TempPix library. However, if you change your mind you can save the photos to your main library or even share them via iMessage, WhatsApp or other apps.

Verdict

The call

The clearest difference is price: TempPix at Free against Star Stacker's $3.99. TempPix also leads on review sentiment (100% vs 56%) and update cadence (every 10 days vs every 6 months). Star Stacker's advantage is ads (none vs shown) and device support (3 vs 1). On in-app purchases and iOS requirement there is nothing between them.
