Rivela.

Rivela helps anime and ACG hobbyists keep model-building work organized without turning the hobby into a messy pile of notes. Create a build table for each kit, break it into sanding, priming, painting, decal, sealing, and assembly steps, then link those steps to paint materials and scheduled work sessions. Track paint codes, thinner ratios, swatch photos, low-stock items, and clear-coat risk notes in a focused local checklist. Use the camera for build progress photos and kit reference shots, import images from Photos for steps and paint swatches, and record short microphone technique reminders on individual step cards. Generate Workshop Proof Sheets that summarize kit progress, material readiness, and upcoming sessions, then save sheets to your photo library when you want a portable build record. Schedule spray booth blocks, drying windows, and hobby desk sessions with prep-gate reminders tied to your build steps. Export session prep cards as shareable images. Manage your workshop coin balance, purchase optional coin packs, and review Terms of Service and Privacy Policy from the Profile tab. Rivela is offline-first. Your build records, appointment notes, photos, and audio reminders stay on your device. The app does not provide a content feed, account system, or remote sync. Optional consumable coin packs support Workshop Proof Sheet creation, saving proof sheets to Photos, material readiness summaries, and session prep card exports.
