Latest updates
2.3.1
• Save where you shot. Switch on Save Location on a frame to keep its GPS spot. It stays on for the following frames until you change it, shows as a pin on the roll, opens in your maps app, and goes into the CSV export.
• Open on Launch. Use Rollio mostly to meter? In Settings, set Open on Launch to Light Meter and the app starts there. Films stays the default.
• iPhone Duo support. Rollio now fits the Duo's wider screen and side toolbar rail, with every form and sheet laid out to stay clear of the edges.
• Also includes bug fixes and stability improvements.
2.1.6
Added Korean and Japanese localization.
