Save your full deal book to iCloud in one tap from Settings → Data, and load it on any device signed into the same Apple ID. Files appear in Files app → iCloud Drive → FlatPrice for sharing. Export & Import. Share your market history and entries as a .json file via AirDrop, email, or any app — perfect for handing a snapshot to a colleague or backing up before a clean install. "As of date" per market entry. Stamp Platts and other overnight prints with their real value date, not just today's, so charts and history reflect when the price was actually set. IMPROVED Cost breakdown now affects landed price. Shipping, agents, surveying, legal, commission, and others fold into the per-MT comparison when quantity is set — not just the discount field. Chart export uses the visible range. The exported PNG now matches whichever range you have selected (7D / 30D / 90D / 1Y/ All) instead of always defaulting to 30D. FIXED Removed phantom drops to zero on the live Market chart for ports whose history doesn't go back as far as others. The line now starts cleanly at each port's first real data point. Tapping a date before a port has any data shows "—" in the tooltip instead of a fabricated zero. ### 1.0.1 — 2026-04-11 - Brand new interactive price chart — drag anywhere to scrub through dates and see every port's value at once, with area fills - Import price history from Excel, Numbers, or Google Sheets - Cost breakdown with landed-price analysis ### 1.0 — 2026-04-10 No release notes. ## More apps by Bruno Maestrini - [Dawn, P.I.](https://appshunter.io/ios/app/dawn-pi/id1567634308) - [Dawn, P.I. - Pocket](https://appshunter.io/ios/app/dawn-pi-pocket/id1567751861) All apps by Bruno Maestrini: https://appshunter.io/developer/1567634310 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
