SliceReel

Turn one video into a scroll-stopping Instagram carousel — right on your iPhone. If you post carousels, you know the drill: take a 60–90 second video, manually trim it into pieces, drop the first clip into Canva to add a cover, export everything, then try to upload it all in the right order — and still not know how your cover will look on your grid until after you've posted. SliceReel does all of that for you in a few taps. WHAT IT DOES • Auto-split — Drop in a video and it splits into clean, equal clips. Choose the number of clips or the seconds per clip; SliceReel keeps you inside Instagram's limits (up to 20 items, 3–60 seconds each) automatically. • Cover on the first frame — Add a text band or import your own cover photo. It's placed on clip 01's first frame — the exact frame Instagram uses as your carousel thumbnail. • Live 3:4 grid preview — Instagram crops your profile grid to 3:4. SliceReel shows the precise crop and a safe-zone overlay, so your cover text never gets cut off. No more surprises after posting. • Smart cover fit — Using a vertical cover on a landscape video? SliceReel keeps your cover's shape and fills the leftover space with black — no stretching, no ugly crops. • Your native aspect ratio — Every clip keeps your video's real dimensions, so all slides match and what you shot is what posts. • Export in order — Clips save to a dated album named 01…NN so they upload in the correct sequence. Mute the audio on export with a single toggle. • Six app icons — Make it yours with a family of icon looks, from Aqua to Sunset to clean mono. PRIVATE BY DESIGN Everything happens on your device. No account, no sign-in, no analytics, no ads, and nothing is ever uploaded. Your videos never leave your iPhone. Made for creators who'd rather spend their time making things than wrangling files.
