"I want to add a note to the photo and save it as it is" - an app that can be used in such a case. Instead of writing text like a notepad, you can leave a photo + note as a single image. What can be done Put a note on the photo You can put text by attaching a memo belt under the photo you selected from the camera roll or the photo you took on the spot. Since it is saved as a single image, you can immediately recognize the "memo of that time" just by looking back at the album. It's OK without a photo You can also create "title card-style" images with only background color + notes without using photos. It can also be used as a slide cover or a piece for SNS. I can give you an image from anywhere If you send an image you are viewing in your browser, email, or other app to this app from "Share", you can add a note to that image and save it. It is convenient to use it, such as attaching a one-word note to a screenshot of the document. You can leave it with a date If you want to leave a "when is a memo", output it with a time stamp. It is also easy to use as a record and trace.

Give text a voice—entirely on your iPhone. FrankenTTS is a private, on-device text-to-speech and voice-cloning playground powered by a pure-Rust speech engine. After a one-time 1.86 GB model download, synthesis runs locally with no cloud inference. • Choose from built-in voices • Clone a voice from a short microphone recording, with a live level meter and automatic background-noise removal • Keep cloned voices in a private on-device voice library; rename, re-record, or delete them whenever you like • Share and import FrankenTTS voice cards—each carries a compact 4 KB voice fingerprint, never the original recording • Generate speech with an editable random seed • See the measured real-time factor for every run • View the waveform, play audio, and share compact M4A files • Turn generated speech into a branded MP4 video • Resume interrupted model downloads with SHA-256 verification Privacy is the default: entered text, microphone audio, voice fingerprints, imported pictures, and synthesized speech are not uploaded. Enrollment recordings are discarded after their on-device voice fingerprint is computed. Voice-card sharing and media export happen only when you explicitly choose them. Only clone or share voices you have the right and consent to use. A recent high-memory iPhone is strongly recommended.
