Ring Sizer vs Dropwise

Ring Sizer is an easy-to-use app for measuring the size of jewelry rings. To determine the size of the ring, place it on the white circle on the phone screen and match the edge of the circle with the inner edge of your ring using the slider. The app will show the size of the ring in different measurement systems. Key features: • ring size determination by measuring its diameter or circumference; • support of metric/imperial measurement units; • support of popular measurement systems (US/CA, AU/GB, EU/ISO, JP/CN, RU); • save measurement results; • a ruler for measuring jewelry and other items.

Dropwise runs your liquid test kit session with you. Getting the number is the easy part. The fiddly part is everything before it: the tube, the drops, the shaking, the five minutes of waiting, and the sinking feeling that you have lost count at drop six. Dropwise puts one instruction on screen at a time — fill to the 5 ml line, add eight drops from bottle one, cap and shake for five seconds — and holds the timers for you. When a test needs five minutes to develop, it starts that timer in the background and moves you straight to the next test, so a full round that would take twenty minutes one after another takes about seven. Each test tells you the moment it is ready, even with the device face-down on the worktop. WHAT IT DOES • Guided sessions for the kits people own — a five-test freshwater liquid kit, a six-test freshwater kit, and a GH & KH drop-count pair • A kit builder for anything else — saltwater, pond, or a brand we have never seen: your tests, your drop counts, your waiting times, your scale values • A drop counter with undo, for the tests where the count is the reading • Overlapping timers with a tray, so the waiting collapses instead of stacking • Numbers, not colour swatches — the printed scale that came with your kit is the only honest reference for colour, and the app says so on every reading • A log of every reading, and hand-drawn trend charts that show the shape of a cycle across ammonia, nitrite and nitrate • Target ranges you set yourself, per tank, from sensible starting points • Cycle-stage reading, free-ammonia chemistry from pH and temperature, and dilution and volume calculators that show their working • Reminders you set yourself • Twelve plain-English articles: what each parameter actually is, the nitrogen cycle, and taking a reading you can trust • Your maintenance log: water changes, filter cleans, livestock, anything WHAT IT WILL NOT DO Dropwise tells you what your numbers are — not what to do about them. It does not prescribe treatments, identify disease, or name products. It cannot see your tank, and decisions about your livestock should be yours. FREE, AND PAID Free forever: one tank, three complete guided sessions, manual logging, your full history, the trends, the insights and calculators, the articles — and the complete JSON backup and restore. Your readings are yours whether you pay or not. One payment unlocks: unlimited guided sessions, unlimited tanks, the kit builder, reminders, custom parameters, CSV export of your readings, and export of your journal for any period. No subscription. Nothing further to pay. PRIVATE BY DESIGN No account. No analytics. No network connection of any kind — the app has no online mode to fall back on, because it has no server. Everything you enter is one file on your own device, and you can export it whenever you like. Dropwise is independent.
