About Cryo
Cryo is a simple yet complete personal finance app. It tracks income, expenses, credit cards, debts, investments and savings goals, and shows everything in one clear overview.
Log money the way you talk
Type or say a phrase like "almoço 32,50 no débito" (lunch 32.50 on debit) or "tv 1200 em 10x no cartão" (TV 1200 in 10 installments on the card). Cryo understands the amount, category, account, date and even installments. You just check and save. It also learns from your corrections.
Features

End-of-month forecast: how much should be left at the current pace, and a daily spending allowance

File backup and spreadsheet (CSV) export

Colors follow your wallpaper (Android 12+), with light and dark themes.

What's new in 1.2
Automatic backup: Cryo saves your data by itself to a folder on your phone, to your cloud (Google Drive, OneDrive, Nextcloud...) or both. Choose how often (daily, weekly or monthly) and, for the folder, whether to always replace the same file or keep several copies. The app still has no internet access. If the place you pick already has a backup, you can restore it right there.
