Tiddle.
Simple, private fluid balance tracking for Android. Log what you drink and measure what you pass, with no account, no cloud, no fuss.
Your personal fluid balance journal.
Tiddle is a focused Android app for anyone who needs to keep an accurate record of their fluid intake and output, without the complexity, clutter, or privacy compromises of most health apps.
Whether you're managing a heart or kidney condition with fluid restrictions, recovering from surgery, caring for a family member at home, or simply monitoring your hydration, Tiddle gives you a clear, straightforward way to log and review your fluid balance.
Everything stays on your device. There are no accounts to create, no cloud services to trust, and no subscriptions to maintain. Your health data belongs to you.
Built for real people.
Managing fluid restrictions
For people with heart failure, kidney disease, or other conditions requiring a daily fluid limit, Tiddle makes it easy to see at a glance whether you're staying within your target.
Post-surgical monitoring
After surgery, accurate fluid balance records are essential. Tiddle gives patients and carers a simple way to keep the log that clinical teams need, without paper charts or complicated spreadsheets.
Home carers and families
Caring for an elderly parent or a family member with a long-term condition often means keeping careful track of fluids. Tiddle gives you a clear record to share with community nurses or GPs.
Hydration and performance
Athletes and those in physically demanding work can use Tiddle to build a clear picture of their intake versus output, helping them optimise hydration and recovery.
Everything you need. Nothing you don't.
Log input instantly
Record fluid intake in millilitres or fluid ounces with a single tap. Choose the unit that suits you and switch at any time in settings.
Log output with type
Record urine and bowel output separately. Volume is optional, so you can log without measuring if needed. Every entry is date and time stamped automatically.
Dated history
All entries are grouped by date. Browse your complete input and output history, expand individual entries, and see your fluid balance over time.
Notes on entries
Add a note to any entry, such as "before medication", "after exercise", or "unusually dark", to give context when reviewing your records or sharing them with a clinician.
Flexible data export
Export your full fluid record in CSV, PDF, Excel, or JSON. Filter by date range to share exactly the period your GP, consultant, or community nurse needs.
Dark mode
Tiddle follows your system's light or dark theme preference automatically. Easy to use at any time of day, including during a night-time visit to the bathroom.

Your health data is sensitive. We treat it that way.
Tiddle stores all data locally on your device using Android's secure storage. We have no servers, no analytics, no advertising SDKs. We can't see your data, and neither can anyone else, unless you choose to export it.
When you do export, you choose exactly what to share, in what format, and with whom. You remain in complete control.
