New in 2.6.4: • On a large iPhone, the Dashboard shows your Best Day and Best Month under the cards, when they fit. • Best Hour and, for consumption, Busiest Hour show the hour with the most energy and its kWh, where Peak Minute repeated the peak. Bug fixes: • After an iPhone restart, the widget shows your figures again instead of asking you to add a system. • Opening HelioPeak now also refreshes the widget. • Fixed a crash on devices set to the Hebrew, Coptic or Ethiopic calendar. • Best Month now counts complete months only, everywhere in the app. • Daily Self-Sufficiency uses your meter readings, and on iPad the live panel no longer reports strong production at dawn. • Clearer Help texts and smaller fixes.

Bug fixes and improvements: • Best Month in the iPad Highlights and on shared cards now counts only completed months. • A negative feed-in tariff now shows as a negative export revenue. • On iPad, a record shared from Highlights now shows the system name. • The status dots of a system in another time zone follow that system's clock. • Polished French texts and smaller fixes.

Bug fixes and improvements, plus: • Easier to read in light mode and at large text sizes. • Charts stay on screen while they refresh. • The Longest Streak now counts only days of strong production, so it may become shorter.

New in 2.6.1: • Compare with another year: in Charts › Week, Month and Year, lay the same period of last year, or of any year you pick, behind your bars as faint bars, with its total and the difference in percent. • Compare your systems day by day: with two or more systems, Charts › Day can show another system's curve on the same day, per kWp so different sizes compare fairly. Improved: • When PVOutput does not answer, HelioPeak now tries once more on a fresh connection after 10 seconds, instead of showing an error after 30 seconds. • The large widget's day curve uses the full height when consumption is not shown. • Missing days in your history keep filling in, even when one stretch of days cannot be loaded for a while.

New in 2.6: • Compare days: in Charts › Day, lay yesterday, the same day last year, your record day or any date over the day you are looking at, with that day's total and the difference in percent. • Compare your systems: with two or more systems, the Week, Month, Year and Total charts put up to four of them side by side, per kWp so different sizes compare fairly. • Monthly report: after each month, the Dashboard offers a one-page PDF per system. Mail, share or save it in one tap; a reminder on the 1st can point you to it. • Output per kWp: the Dashboard, Charts and Detailed Data show your production per kWp, for every day and period. • One day as CSV: export a day's readings from Charts › Day. Improved: • Before iOS asks, HelioPeak explains what it will notify you about. • HelioPeak now reads an answer from PVOutput correctly even when it starts with stray characters. • New Help & FAQ sections, with ⓘ buttons for the new features.

New in 2.5.1: • Ready for iPhone Duo, folded and unfolded. Folded in landscape, the chart now fills the screen, and the Dashboard shows your system, the day and today's production on the title line. • Faster day arrows in Charts: the previous day's curve stays on screen, dimmed, until the next day has loaded. Improved: • The "avg" label on the average line is easier to read. • The unit on the Average cards now appears in your language. • The Specific Yield title in System Details is no longer cut off. Its explanation is in Help & FAQ.

New in 2.5 • Siri and Shortcuts: ask how much your system produced today, yesterday or this month, without opening the app. • Arrows in Charts: step one day, week, month or year at a time, or tap the date to jump to any period. • Your own target: the monthly estimates you entered on pvoutput.org appear as a dashed line in the Week, Month and Year charts, and System Details shows how this year compares. • Solar Moments statistics: all your moments at a glance, the records to beat and the next milestone. • Take your Solar Moments with you: export them to a file and import them on another device. • System Details now shows how much of your PVOutput history is loaded. Improved • A more complete history on free PVOutput accounts. • A system in another time zone follows its own day, in the app and in the widgets. • Fewer requests to PVOutput, and a clear notice when the hourly limit is reached. • Clearer widgets: yesterday's total and out-of-date figures are marked. • Privacy: turning off anonymous usage data stops analytics and crash reports at once, and the support e-mail no longer includes your system's location. • More accurate self-use and net export figures, keyboard shortcuts on iPad, better VoiceOver labels and many smaller fixes.

Fixes a first-launch problem where no system was active and the appearance setting did not apply until you restarted the app. Times now follow your device's 12/24-hour format again, and the comparison view no longer shows a percentage for today while the day is still running. Monthly and year-to-date figures keep theirs, marked "so far".

New: HelioPeak widgets for your Lock Screen, in round and rectangular shapes. Also: the yearly chart now shows both production and consumption when you tap a bar, the iPad weather display recovers on its own after a network problem, and the "PVOutput is temporarily unavailable" message no longer appears when it shouldn't. Privacy: crash reports no longer contain any system identifier, and eleven unused measurements have been removed from the app. Plus translation fixes and improvements to stability and speed.
