Start with the product you use.

Yes. Folio is now Zolio. Only the name changed: the same app, the same journal, and all your existing entries and backups carry over. If you installed it as Folio, it becomes Zolio on the next update, with nothing to reinstall or migrate.

Yes. Zolio stores your notebook locally by default. If you enable backup, Zolio copies it only to the personal Google Drive or iCloud account you choose, never to Zolio or PurposeLab servers or unrelated third parties. Export and sharing also happen only when you choose a destination. If other people use your phone, it is worth reading what actually happens when someone opens your journal and what to do about it.

Yes. Zolio includes an app lock feature using your device's biometric authentication (fingerprint or face unlock) or PIN. Enable it in Settings.

Yes. Export creates a file and lets you choose where it goes. Optional backup copies the complete notebook only to the personal Google Drive or iCloud account you choose. Neither path sends notebook content to Zolio or PurposeLab servers.

Uninstalling deletes the notebook stored on this phone. A backup you placed in your personal Google Drive or iCloud account remains there and can be restored after reinstalling. Without a backup, the local notebook cannot be recovered.

Yes. The core stays free forever: journal entries, mood, habits, and monthly reflections. Zolio Plus is optional and adds extra themes, fonts, and widgets. You can take it monthly or pay once for lifetime, and you are never blocked from writing.

No. WaterWise is completely ad-free. You'll never see ads on the logging screen, in notifications, or anywhere in the app.

You can set custom reminders throughout the day. WaterWise respects Do Not Disturb mode and works with battery optimization on all Android phones.

Yes. WaterWise works completely offline. All your data is stored locally on your device. No internet connection is required.

Yes. You can set your target water intake based on your body weight, activity level, and preferences. The app also supports custom cup sizes.

No. WaterWise is free and there is nothing to buy inside it. If we ever add extras, it will be a small one-time purchase rather than a subscription.

No. BP Log is a companion app for your home blood pressure monitor (cuff device). You take a reading with your monitor and enter the numbers into the app. BP Log does not use your phone's sensors to measure blood pressure.

No. Your BP Log readings stay on your phone. BP Log has no servers, no account and no cloud storage; readings are stored locally in a database on your device.

Yes. You can generate a PDF or CSV report from the app and share it via email, WhatsApp, or any other app. This is useful for sharing with your doctor. If you would rather keep a copy on paper as well, there is a free log sheet you can print.

BP Log uses the American Heart Association (AHA) 2017 categories: Normal (below 120/80), Elevated (120-129 with diastolic below 80), Stage 1 (130-139 or 80-89), Stage 2 (140 or higher, or 90 or higher), and Crisis (systolic higher than 180 and/or diastolic higher than 120).

Your data will be lost. Since everything is stored locally, uninstalling the app deletes your readings. We recommend exporting a PDF or CSV backup regularly.

Yes. All sounds are included in the app. No internet connection is needed to play them.

Hushly is optimized for overnight use. It handles battery restrictions on Samsung, Xiaomi, OnePlus, and other Android phones. Use the sleep timer to stop playback automatically.

Check the app for the latest mixing features. We're continuously improving Hushly based on parent feedback.

No subscription. Hushly is free to use, and the optional Premium unlock is a one-time purchase you buy once and keep.

Yes. Every app is free to use and none of them show ads. Zolio, Hushly and Crumbs have an optional paid tier for extras (Zolio Plus, Hushly Premium, Crumbs Pro and Max); WaterWise and BP Log have nothing to buy at all. Nothing you need day to day sits behind a paywall.

We collect minimal anonymous analytics (crash reports and basic usage patterns) to improve our apps, and we never sell your data. Zolio keeps notebook content on-device by default; if you enable backup, it goes only to the personal Google Drive or iCloud account you choose, never to Zolio or PurposeLab servers. WaterWise, BP Log and Hushly keep their core content on-device. Crumbs runs inside WhatsApp and stores messages and the user's number to answer them. See our privacy policies for details.
