About

Rondo

Features
Read full description

Round video messages are fun to record and painful to share anywhere else. Saved from the chat, they turn into square files with the circle stuck on a white background. Rondo fixes that in seconds, records new circles, and now captions them too: • Record circles right in the app: hold to record, slide up onto the lock to go hands-free, zoom, flip cameras mid-recording, flash • Or import a saved video from Photos • The circle is detected automatically and the white corners are gone • Auto-captions turn speech into editable subtitles: fix any line, pick a style, and they are rendered right into the video • Pick a background: a soft blur of the video itself, or any color • Export as a square, as 9:16 for Stories, Reels, and TikTok, or full-frame without the circle • Sound stays untouched, and a mute button can drop it entirely The preview is exactly what you export. No account, and nothing ever reaches us: the app collects no data at all. Rondo Pro (one-time purchase) removes the watermark and unlocks 9:16 export, custom colors, and captions. The free version is fully usable forever. Works with round video messages saved from Telegram and similar apps. Rondo is an independent app, not affiliated with Telegram.
