Yes. Undo last count puts the row back, together with anything else that tap changed. If you need a bigger correction, Edit count lets you set the number you actually read off your work — Rowmori saves a checkpoint first so you can come back.
On the old phone: Settings → Export a backup file, then share it to yourself. On the new one: Settings → Import a backup file. The import shows you what it would replace before it changes anything.
Pattern images are not inside the backup file, so add those again on the new phone.
A save did not reach your device's storage, usually because it is full. Rowmori shows the number that is genuinely saved rather than the one you just tapped, so nothing is silently lost. Free up some space and press Try again.
Entirely. Every feature works with no connection at all, there is no account, and nothing you count, write or import is ever uploaded. The only network calls it makes are a once-a-day check for its own settings, and — if you turn on Help improve Rowmori — anonymous crash and usage reports. See the privacy policy.
Not yet. Rowmori supports pattern rows you type or paste, and photos or charts as images. A PDF reader is deliberately not shipped until it can be relied on, rather than added as an import that half works.
What helps most: your phone model and OS version, what you were doing, and what you expected instead. If you can, export a backup before sending anything, so your work is safe while we look.
